NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Dollar and share amounts in thousands, except per-share data)

(Unaudited)

1.   The Company

Based in Sunnyvale, California, Network Appliance was incorporated in California in April 1992 and reincorporated in Delaware in November 2001. Network Appliance, Inc. is a leading supplier of enterprise storage and data management software and hardware products and services. Our solutions help global enterprises meet major information technology challenges such as managing storage growth, assuring secure and timely information access, protecting data, and controlling costs by providing innovative solutions that simplify the complexity associated with managing corporate data. Network Appliance^tm solutions are the data management and storage foundation for many of the world’s leading corporations and government agencies. In the following notes to our interim condensed consolidated financial statements, Network Appliance is also referred to as “we,” “our,” and “us.”

2.   Condensed Consolidated Financial Statements

The accompanying interim unaudited condensed consolidated financial statements have been prepared by Network Appliance, Inc. without audit and reflect all adjustments, consisting only of normal recurring adjustments which are, in the opinion of management, necessary for a fair presentation of our financial position, results of operations, and cash flows for the interim periods presented. The statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“generally accepted accounting principles”) for interim financial information and in accordance with the instructions toForm 10-Q andArticle 10-01 ofRegulation S-X. Accordingly, they do not include all information and footnotes required by generally accepted accounting principles for annual consolidated financial statements. Certain prior period balances have been reclassified to conform with the current period presentation.

We operate on a52-week or53-week year ending on the last Friday in April. For presentation purposes we have indicated in the accompanying interim unaudited condensed consolidated financial statements that our fiscal year end is April 30. The first six months of fiscal 2007 and 2006 were both26-week fiscal periods.

These financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes included in our Annual Report onForm 10-K for the year ended April 30, 2006. The results of operations for the quarter ended October 27, 2006 are not necessarily indicative of the operating results to be expected for the full fiscal year or future operating periods.

In fiscal 2006, we began to separately disclose software subscriptions revenue and cost of software subscriptions revenue in our income statements. All prior periods have been revised to reflect this presentation. Such balances were previously included as a part of product revenue and cost of product revenue and disclosed separately in our footnotes.

3.   Significant Accounting Policies and Use of Estimates

Revenue Recognition:  We apply the provisions of Statement of Position (“SOP”)No. 97-2,Software Revenue Recognition, and related interpretations to our product sales, both hardware and software, because our software is essential to the performance of our hardware. We recognize revenue when:

•  Persuasive evidence of an arrangement exists:  It is our customary practice to have a purchase orderand/or contract prior to recognizing revenue on an arrangement from our end users, customers, value-added resellers, or distributors.

•  Delivery has occurred:  Our product is physically delivered to our customers, generally with standard transfer terms such as FOB origin. We typically do not allow for restocking rights with any of our value-added resellers or distributors. Products shipped with acceptance criteria or return rights are not recognized

NETWORK APPLIANCE, INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

as revenue until all criteria are achieved. If undelivered products or services exist that are essential to the functionality of the delivered product in an arrangement, delivery is not considered to have occurred.

•  The fee is fixed or determinable:  Arrangements with payment terms extending beyond our standard terms, conditions and practices are not considered to be fixed or determinable. Revenue from such arrangements is recognized as the fees become due and payable. We typically do not allow for price-protection rights with any of our value-added resellers or distributors.

•  Collection is probable:  Probability of collection is assessed on acustomer-by-customer basis. Customers are subjected to a credit review process that evaluates the customers’ financial position and ultimately their ability to pay. If it is determined at the outset of an arrangement that collection is not probable based upon our review process, revenue is recognized upon cash receipt.

Our multiple element arrangements include our systems and generally may also include one or more of the following undelivered elements: installation services, software subscriptions, premium hardware maintenance and storage review services. If the arrangement contains both software-related and non-software-related elements, we allocate revenue to the non-software elements based on objective and reliable evidence of fair value in accordance with Emerging Issues Task Force (“EITF”)00-21,Revenue Arrangements with Multiple Deliverables.Non-software elements are items for which the functionality of the software is not essential to its performance; the non-software-related elements in our arrangements may consist of storage optimization reviews (which are sold only within a bundled service offering that also contains software-related services), technical consulting,and/or installation services. For undelivered software-related elements, we apply the provisions ofSOP 97-2 and determine fair value of these undelivered software-related elements based on vendor-specific objective evidence which for us consists of the prices charged when these services are sold separately.

For arrangements with multiple elements, we recognize as revenue the difference between the total arrangement price and the greater of fair value or stated price for any undelivered elements (“the residual method”).

Our software subscriptions entitle our customers to receive unspecified product upgrades and enhancements on awhen-and-if-available basis, bug fixes, and patch releases. Premium hardware maintenance services include contracts for technical support and minimum response times. Revenue from software subscriptions and premium hardware maintenance services is recognized ratably over the contractual term, generally one to three years; standard hardware warranty costs are considered an obligation under Statement of Financial Accounting Standards (“SFAS”) No. 5,Accounting for Contingencies, and are expensed to cost of revenues when revenue is recognized. We also offer extended service contracts (which may include standard warranty as well as premium hardware maintenance) at the end of the warranty term; revenues from these contracts are recognized ratably over the contract term. When storage optimization reviews are sold as a bundled element with our software subscriptions and premium hardware maintenance services, the revenue is recognized ratably over the contract term. We typically sell technical consulting services separately from any of our other revenue elements, either on a time and materials basis or for fixed-price standard projects; we recognize revenue for these services as they are performed. Revenue from hardware installation services is recognized at the time of delivery and any remaining costs are accrued, as the remaining undelivered services are considered to be inconsequential and perfunctory.

We record reductions to revenue for estimated sales returns at the time of shipment. Sales returns are estimated based on historical sales returns, current trends, and our expectations regarding future experience. Reductions to revenue associated with sales returns include consideration of historical sales levels, the timing and magnitude of historical sales returns, and a projection of this experience into the future. We monitor and analyze the accuracy of sales returns estimates by reviewing actual returns and adjust them for future expectations to determine the adequacy of our current and future reserve needs. If actual future returns and allowances differ from past experience, additional allowances may be required.

Stock-Based Compensation:  We estimate the fair value of stock options using the Black-Scholes valuation model, consistent with the provisions of the Financial Accounting Standards Board’s (FASB) SFAS No. 123

7

NETWORK APPLIANCE, INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

(revised 2004),Share-Based Payment(SFAS No. 123R) as interpreted by Staff Accounting Bulletin (SAB) No. 107. Option-pricing models require the input of highly subjective assumptions, including the expected term of options, the determination of risk-free interest rates, and the expected price volatility of the stock underlying such options. In addition, we estimate the number of share-based awards that will be forfeited due to employee turnover based on historical trends. Finally, we capitalize into inventory a portion of the periodic stock-based compensation expense that relates to employees working in manufacturing activities.

In November 2005, FASB issued Financial Statement Position, or FSP, onSFAS No. 123R-3 (FSPNo. 123R-3),Transition Election Related to Accounting for Tax Effects of Share-Based Payment Awards.  Effective upon issuance, FSPNo. 123R-3 provides for an alternative transition method for calculating the tax effects of stock-based compensation expense pursuant to SFAS No. 123R. The alternative transition method provides simplified approaches to establish the beginning balance of a tax benefit pool comprised of the additional paid-in capital, or APIC, related to the tax effects of employee stock-based compensation expense, and to determine the subsequent impact on the APIC tax benefit pool and the statement of cash flows of stock-based awards that were outstanding upon the adoption of SFAS No. 123R. Because we have not made the election to use the simplified approach to establish the beginning balance of the tax benefit pool, the tax effects of stock-based compensation expense were calculated as if SFAS 123 had always been applied for recognition purposes. For awards that are both fully vested and partially vested as of the date of adoption, the financing cash inflow is the excess tax benefit computed as if Statement 123 had always been applied for recognition purposes.

Use of Estimates:  The preparation of the condensed consolidated financial statements is in conformity with generally accepted accounting principles and requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Such estimates include, but are not limited to, revenue recognition and allowances; valuation of goodwill and intangibles; accounting for income taxes; inventory reserves and write-down; restructuring accruals; impairment losses on investments; accounting for stock-based compensation; and loss contingencies. Actual results could differ from those estimates.

4.   Stock-based Compensation

Effective May 1, 2006, we adopted SFAS No. 123R,Share-Based Payments (SFAS No. 123R), which provides guidance on accounting for stock-based awards for employee services. We elected to adopt the modified prospective method, and accordingly we were not required to restate our prior period financial statements.

Prior to the adoption of SFAS No. 123R

Prior to the adoption of SFAS No. 123R, stock-based compensation expense had not been recognized in our consolidated statement of operations, other than those related to acquisitions. As a result of adopting SFAS No. 123R, pre-tax stock-based compensation expense recorded for the three- and six-month periods ended October 27, 2006 of $42,423 and $85,445, respectively, was related to employee stock options, restricted stock units (RSUs), restricted stock awards (RSAs), and employee stock purchases under our Employee Stock Purchase Plan. Pre-tax stock-based compensation expense of $3,344 and $5,372 for the three- and six-month periods ended October 28, 2005, respectively, which we recorded under APB No. 25, was related to RSUs, RSAs, and options assumed from acquisitions.

As a result of adoption of SFAS No. 123R, our income from operations and net income for the three-month period ended October 27, 2006 were $37,364 and $29,782 lower, respectively, and $75,268 and $62,128 lower, respectively, for the six-month period ended October 27, 2006, than they would have been if we had continued to account for share-based compensation under APB No. 25. Basic and diluted earnings per share for the three-month period ended October 27, 2006, were each $0.08 lower, and basic diluted earnings per share for the six months ended October 28, 2006 were $0.17 and $0.16 lower, respectively, than they would have been if we had continued to

8

NETWORK APPLIANCE, INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

account for share-based compensation under APB No. 25. We currently estimate that the impact of adopting SFAS No. 123R on our fiscal year ending April 30, 2007 will be between $0.33 and $0.40 per share.

As required by SFAS No. 123R, we eliminated the unamortized deferred stock compensation of $49,266 on May 1, 2006. Our common stock and additional paid-in capital were also reduced by the same amount and had been included in the Stockholders Equity of our Consolidated Balance Sheets as of April 30, 2006.

Had compensation expense been determined based on the fair value at the grant date for awards, consistent with the provisions of SFAS No. 123, our pro forma net income and pro forma net income per share for the three- and six-month periods ended October 28, 2005, would be as follows:

	Three Months Ended			Six Months Ended
	October 28,			October 28,
	2005			2005
Net income as reported	$	70,718		$	130,838
Add: stock-based employee compensation expense included in reported net income under APB No. 25, net of related tax effects		2,006			3,223
Deduct: total stock-based compensation determined under fair value based method for all awards, net of related tax effects		(24,716	)		(49,364	)
Pro forma net income	$	48,008		$	84,697
Basic net income per share, as reported	$	0.19		$	0.35
Diluted net income per share, as reported	$	0.18		$	0.34
Basic net income per share, pro forma	$	0.13		$	0.23
Diluted net income per share, pro forma	$	0.12		$	0.22

SFAS No. 123R requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. In our pro forma information required under SFAS No. 123 for the periods prior to fiscal 2007, we reflect cancellations and forfeitures due to employee terminations as they occurred.

The stock-based compensation expenses included in the Condensed Consolidated Statement of Income for the three- and six-month periods ended October 27, 2006 are as follows:

	Three Months Ended			Six Months Ended
	October 27,			October 27,
	2006			2006
Cost of product revenue	$	1,069		$	1,739
Cost of service revenue		2,489			5,123
Sales and marketing		18,715			37,432

Income taxes		(7,447	)		(15,281	)
Total stock-based compensation expense after income taxes		34,976			70,164

The following table summarizes stock-based compensation associated with each type of award:

	Three Months Ended			Six Months Ended
	October 27,			October 27,
	2006			2006
Employee stock options and awards	$	39,174		$	79,297

Income taxes		(7,447	)		(15,281	)
Total stock-based compensation expense after income taxes		34,976			70,164

In conjunction with the adoption of SFAS No. 123R, we changed our accounting policy of attributing the fair value of stock-based compensation to expense from the accelerated multiple-option approach provided by APB No. 25, as allowed under SFAS No. 123, to the straight-line single-option approach. Compensation expense for all stock-based payment awards expected to vest that were granted on or prior to April 30, 2006 will continue to be recognized using the accelerated multiple-option method. Compensation expense for all stock-based payment awards expected to vest that were granted subsequent to April 30, 2006 is recognized on a straight-line basis under the single-option approach.

Income Tax Benefits Recorded in Stockholders Equity

For the three- and six-month periods ended October 27, 2006, the total income tax benefit associated with employee stock transactions was $49,033 and $79,020, respectively. For both the three- and six-month periods ended October 28, 2005, the total income tax benefit associated with employee stock transactions was $16,289.

Income Tax Effects on Statements of Cash Flows

In accordance with SFAS No. 123R, we have presented tax benefits resulting from tax deductions in excess of the compensation cost recognized for those options as financing cash flows for the six-month period ended October 27, 2006. Prior to the adoption of SFAS No. 123R, tax benefits of stock option exercises were presented as operating cash flows. Tax benefits, related to tax deductions in excess of the compensation cost recognized, of $23,845 presented as financing cash flows for the six-month period ended October 27, 2006, would have been classified as operating cash flows if we had not adopted SFAS No. 123R.

Valuation Assumptions

In compliance with SFAS No. 123R, we estimated the fair value of stock options using the Black-Scholes model on the date of the grant. Assumptions used in the Black-Scholes valuation model were as follows:

	Stock Options			ESPP			Stock Options			ESPP
	Three Months Ended			Three Months Ended			Six Months Ended			Six Months Ended
	October 27,			October 27,			October 27,			October 27,
	2006			2006			2006			2006
Expected life in years(1)		4.0			0.5			4.0			0.5
Risk-free interest rate(2)		4.73	%		5.06	%		4.90	%		5.02	%
Volatility(3)		37	%		37	%		36	%		37	%
Expected dividend(4)		0	%		0	%		0	%		0	%

(1)	The expected life of 4.0 years represented the period that our stock-based award was expected to be outstanding and was determined based on historical experience on similar awards. The expected life of 0.5 years for the purchase was based on the term of the purchase period of the purchase plan.
(2)	The risk-free interest rate for the options was based upon U.S. Treasury bills with equivalent expected terms of our employee stock-based award. The risk-free interest rate for purchases was based upon U.S. Treasury bills yield curve in effect at the time of grant for the expected term of the purchase period.
(3)	We used the implied volatility of traded options to estimate our stock price volatility. Prior to adoption of SFAS No. 123R, we estimated volatility based upon historical volatility rates as required by SFAS No. 123.
(4)	The expected dividend was determined based on our history and expected dividend payouts.

As required by SFAS No. 123R, we estimate our forfeiture rates based on historical voluntary termination behavior.

The intrinsic value represents the difference between the exercise price of stock options and the market price of our stock on that day for allin-the-money options. The weighted-average fair value as of the grant date was $12.67. The total intrinsic value of options exercised was $90,948 and $117,331 for the three- and six-month periods ended October 27, 2006, respectively, and $31,977 and $93,359 for the three- and six-month periods ended October 28, 2005, respectively. We received $55,627 and $74,947 from the exercise of stock options for the three- and six-month periods ended October 27, 2006, respectively, and received $21,749 and $58,199 from the exercise of stock options for the three- and six-month periods ended October 28, 2005, respectively.

Although non-vested shares are legally issued, they are considered contingently returnable shares subject to repurchase by the Company when employees terminate their employment. The total fair value of shares vested during the three- and six-month periods ended October 27, 2006 was $209 and $2,028, respectively. There was $24,179 of total unrecognized compensation as of October 27, 2006 related to restricted stock awards. The unrecognized compensation will be amortized over a weighted-average period of 1.6 years.

5.   Debt

On March 31, 2006, Network Appliance Global LTD. (“Global”), a subsidiary of the Company, entered into a loan agreement (the “Loan Agreement”), with the lenders and JPMorgan Chase Bank, National Association, as administrative agent. The Loan Agreement provides for a term loan available in two tranches, a tranche of $220,000 (“Tranche A”) and a tranche of $80,000 (“Tranche B”), for an aggregate borrowing of $300,000. The proceeds of

the term loan have been used to finance a dividend from Global to the Company under the American Jobs Creation Act. The Tranche A term loan and Tranche B term loan, together with accrued and unpaid interest, are due in full on the maturity date of March 31, 2008. Loan repayments of $105,061 and $88,367 are due in the remainder of fiscal 2007 and in fiscal 2008, respectively.

Interest for both the Tranche A and Tranche B term loan accrues at a floating rate based on the base rate in effect from time to time, plus a margin, which totaled 5.45% at October 27, 2006.

During the three- and six-month periods ended October 27, 2006, we made a repayment of $78,706 and $106,572, respectively, on the term loan. The Tranche A term loan is secured by certain investments totaling $189,728 as of October 27, 2006 held by Global and the Tranche B term loan is secured by a pledge of accounts receivable by Global’s subsidiary, Network Appliance B.V.

As of October 27, 2006, Global is in compliance with all debt covenants as required by the Loan Agreement.

Management evaluates investments on a regular basis to determine if another-than-temporary impairment has occurred, and there were no such impairment as of October 27, 2006. The unrealized losses on these investments at October 27, 2006 were primarily due to interest rate fluctuations. We have the ability and intent to hold these

investments until recovery of their carrying values. We also believe that we will be able to collect all principal and interest amounts due to us at maturity given the high credit quality of these investments. Accordingly, we do not consider these investments to beother-than-temporarily impaired at October 27, 2006.

8.   Goodwill and Intangible Assets

Goodwill is reviewed annually for impairment (or more frequently if indicators of impairment arise). We completed our annual impairment assessment in fiscal 2006 and concluded that goodwill was not impaired. In the three- and six month periods ended October 27, 2006, there were no indicators that would suggest the impairment of goodwill and intangible assets. During the second quarter of fiscal year 2007, we recorded a reduction of goodwill for $1,180 in connection with the divestiture of certain NetCache assets.

Intangible assets are summarized as follows:

9.   Derivative Instruments

As a result of our significant international operations, we are subject to risks associated with fluctuating exchange rates. We use derivative financial instruments, principally currency forward contracts and currency options, to attempt to minimize the impact of exchange rate movements on our balance sheet and operating results. Factors that could have an impact on the effectiveness of our hedging program include the accuracy of forecasts and the volatility of foreign currency markets. These programs reduce, but do not always entirely eliminate, the impact of currency exchange movements. The maturities of these instruments are generally less than one year.

Currently, we do not enter into any foreign exchange forward contracts to hedge exposures related to firm commitments or equity investments. Our major foreign currency exchange exposures and related hedging programs are described below:

Balance Sheet Exposures:  We utilize foreign currency forward and options contracts to hedge exchange rate fluctuations related to certain foreign assets and liabilities. Gains and losses on these derivatives offset gains and losses on the assets and liabilities being hedged and the net amount is included in earnings. For the three-month period ended October 27, 2006, net gains generated by hedged assets and liabilities totaled $565 and were offset by losses on the related derivative instruments of $388. For the six-month period ended October 27, 2006, net gains generated by hedged assets and liabilities and related derivative instruments totaled $544 and $275, respectively. For the three-month period ended October 28, 2005, net gains generated by hedged assets and liabilities totaled $137 and were offset by losses on the related derivative instruments of $302. For the six-month period ended October 28, 2005, net losses generated by hedged assets and liabilities totaled $3,576 and were offset by gains on the related derivative instruments of $3,148.

The premiums paid on the foreign currency option contracts are recognized as a reduction to other income when the contract is entered into. Other than the risk associated with the financial condition of the counterparties, our maximum exposure related to foreign currency options is limited to the premiums paid.

Forecasted Transactions:  We use currency forward contracts to hedge exposures related to forecasted sales and operating expenses denominated in certain foreign currencies. These contracts are designated as cash flow hedges and in general closely match the underlying forecasted transactions in duration. The contracts are carried on the balance sheet at fair value and the effective portion of the contracts’ gains and losses is recorded as other comprehensive income until the forecasted transaction occurs.

If the underlying forecasted transactions do not occur, or if it becomes probable that they will not occur, the gain or loss on the related cash flow hedge is recognized immediately in earnings. For the three- and six-month periods ended October 27, 2006 and October 28, 2005, we did not record any gains or losses related to forecasted transactions that did not occur or that became improbable.

17

NETWORK APPLIANCE, INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

We measure the effectiveness of hedges of forecasted transactions on at least a quarterly basis by comparing the fair values of the designated currency forward contracts with the fair values of the forecasted transactions.

As of October 27, 2006, the notional fair values of foreign exchange forward and foreign currency option contracts totaled $325,750.

10.   Earnings Per Share

Basic net income per share is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding excluding unvested restricted stock for that period. Diluted net income per share is computed giving effect to all dilutive potential shares that were outstanding during the period. Dilutive potential common shares consist of incremental common shares subject to repurchase, common shares issuable upon exercise of stock options, and restricted stock awards.

During all periods presented, we had certain options outstanding, which could potentially dilute basic earnings per share in the future, but were excluded in the computation of diluted earnings per share in such periods, as their effect would have been antidilutive. These certain options were antidilutive in the three- and six-month periods ended October 27, 2006 and October 28, 2005 as these options’ exercise prices were above the average market prices in such periods. For the three-month periods ended October 27, 2006 and October 28, 2005, 23,493 and 21,853 shares of common stock options with a weighted average exercise price of $44.34 and $44.85, respectively, were excluded from the diluted net income per share computation. For the six-month periods ended October 27, 2006 and October 28, 2005, 24,234 and 18,718 shares of common stock options with a weighted average exercise price of $43.51 and $48.52, respectively, were excluded from the diluted net income per share computation.

The following is a reconciliation of the numerators and denominators of the basic and diluted net income per share computations for the periods presented:

12.   Divestiture

On September 11, 2006, we completed the sale of certain assets of our NetCache product line to Blue Coat Systems Inc. (“Blue Coat”), as previously discussed in our annual report onForm 10-K. We received $23,914 in cash and 360 shares of Blue Coat’s common stock with a fair value of $4,637. In addition, we accrued $2,032 for costs expected to be incurred to fulfill our engineering and service contractual obligations. Because of these continuing obligations, the NetCache sale does not qualify for presentation as a discontinued operation. We recorded revenues of $37,852 and $31,639 from NetCache products for the six months ended October 27, 2006 and

19

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

October 28, 2005 respectively; the contribution to operating income from these products was not significant. As a result of this divestiture, we recorded a pre-tax gain of $25,339 in our income from operations and a reduction of goodwill of $1,180.

13.   Restructuring Charges

In fiscal 2002, as a result of continuing unfavorable economic conditions and a reduction in IT spending rates, we implemented two restructuring plans, which included reductions in our workforce and consolidations of our facilities. As of October 27, 2006, we have no outstanding balance in our restructuring liability for the first restructuring. The second restructuring related to the closure of an engineering facility and consolidation of resources to the Sunnyvale headquarters. In fiscal 2006, we implemented a third restructuring plan related to the move of our global services center operations from Sunnyvale to our new flagship support center at our Research Triangle Park facility in North Carolina. Of the reserve balance at October 27, 2006, $542 was included in other accrued liabilities and the remaining $1,832 was classified as long-term obligations.

Our restructuring estimates are reviewed and revised periodically and may result in a substantial charge or reduction to restructuring expense should different conditions prevail than were anticipated in previous management estimates. Such estimates included various assumptions such as the time period over which the facilities will be vacant, expected sublease terms, and expected sublease rates. During the quarter ended October 27, 2006, we did not record any reduction or charges in the restructuring reserve.

14.   New Accounting Pronouncements

In September, 2006, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards (“SFAS”) No. 157,Fair Value Measurements. SFAS No. 157 provides a framework for measuring fair value, clarifies the definition of fair value, and expands disclosures regarding fair value measurements. SFAS No. 157 does not require any new fair value measurements and eliminates inconsistencies in guidance found in various prior accounting pronouncements. We are required to adopt SFAS No. 157 for our fiscal year beginning May 1, 2008. We are currently evaluating the effect that the adoption of SFAS No. 157 will have on our consolidated results of operations and financial condition, but do not expect it to have a material impact.

In September 2006, the SEC issued Staff Accounting Bulletin (“SAB”) No. 108,Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements. SAB No. 108 provides guidance on how prior year misstatements should be taken into consideration when quantifying misstatements in current year financial statements for purposes of determining whether the current year’s financial statements are materially misstated. SAB No. 108 is effective for fiscal years ending on or after November 15, 2006.

We are required to adopt SAB No. 108 for our fiscal year beginning on May 1, 2007. We are currently evaluating the effect that the adoption of SAB No. 108 will have on our consolidated results of operations and financial condition.

In July 2006, the Financial Accounting Standards Board (“FASB”) issued FASB Interpretation No. 48,Accounting for Uncertainty in Income Taxes — an Interpretation of FASB Statement No. 109(FIN No. 48). FIN No. 48 prescribes a comprehensive model for how a company should recognize, measure, present, and disclose in its financial statements uncertain tax positions that the Company has taken or expects to take on a tax return (including a decision whether to file or not to file a return in a particular jurisdiction). FIN No. 48 is applicable to all uncertain tax positions for taxes accounted for under FASB Statement No. 109,Accounting for Income Taxes(SFAS No. 109), and substantially changes the applicable accounting model. FIN No. 48 is likely to cause greater volatility in income statements as more items are recognized discretely within income tax expense. We are required to adopt FIN No. 48 for fiscal years beginning after May 1, 2007. We are currently evaluating the effect that the adoption of FIN No. 48 will have on our consolidated results of operations and financial condition but do not expect it to have a material impact.

15.   Commitments and Contingencies

The following summarizes our commitments and contingencies at October 27, 2006, and the effect such obligations may have on our future periods:

(1) We lease sales offices and research and development facilities throughout the U.S. and internationally. These sales offices are leased under operating leases which expire through fiscal 2016. We are responsible for certain maintenance costs, taxes, and insurance under these leases. Substantially all lease agreements have fixed payment terms based on the passage of time. Some lease agreements provide us with the option to renew or terminate the lease. Our future operating lease obligations would change if we were to exercise these options and if we were to enter into additional operating lease agreements. Rent operating lease payments in the table exclude lease payments which are accrued as part of our fiscal 2002 restructurings and include only rent lease commitments that are over one year.

(2)	On December 16, 2005, we entered into financing, construction, and leasing arrangements with BNP Paribas LLC (“BNP”) for office space to be located on land currently owned by us in Sunnyvale, California. This arrangements requires us to lease our land to BNP for a period of 50 years to construct approximately 190,000 square feet of office space costing up to $38,500. After completion of construction, we will pay minimum lease payments, which vary based on London Interbank Offered Rate (“LIBOR”) plus a spread (6.07% at October 27, 2006) on the cost of the facilities. We expect to begin paying lease payments on the completed buildings on September 2007 for a term of five years. We have the option to renew the lease for two consecutive five-year periods upon approval by BNP.
	Upon expiration (or upon any earlier termination) of the lease term, we must elect one of the following options: We may (i) purchase the building from BNP for $38,500, (ii) if certain conditions are met, arrange for the sale of the building by BNP to a third party for an amount equal to at least $32,725, and be liable for any deficiency between the net proceeds received from the third party and $32,725, or (iii) pay BNP a supplemental payment of $32,725, in which event we may recoup some or all of such payment by arranging for a sale of the building by BNP during the ensuing two-year period.
	Included in the above contractual cash obligations are (a) lease commitments of $1,363 in fiscal 2008; $2,337 in each of the fiscal years 2009, 2010, 2011, and 2012; and $974 in fiscal 2013, which are based on the LIBOR rate at October 27, 2006 for a term of five years, and (b) at the expiration or termination of the lease, a supplemental payment obligation equal to our minimum guarantee of $32,725 in the event that we elect not to purchase or arrange for a sale of the building.
	The lease also requires us to maintain specified financial covenants with which we were in compliance as of October 27, 2006. Such specified financial covenants include a maximum ratio of Total Debt to Earnings Before Interest, Taxes, Depreciation and Amortization (“EBITDA”) and a Minimum Unencumbered Cash and Short Term Investments.
(3)	Equipment operating leases include servers and IT equipment used in our engineering labs and data centers.
(4)	Venture capital funding commitments include a quarterly committed management fee based on a percentage of our committed funding to be payable through June 2011.
(5)	Capital expenditures include worldwide contractual commitments to purchase equipment and to construct building and leasehold improvements, which will be recorded as Property and Equipment.
(6)	We are required to pay based on a minimum volume under certain communication contracts with major telecommunication companies as well as maintenance contracts with multiple vendors. Such obligations expire in April 2010.
(7)	The amounts outstanding under these letters of credit relate to workers’ compensation, a customs guarantee, a corporate credit card program, and a foreign rent guarantee.

As of October 27, 2006, our notional fair values of foreign exchange forward and foreign currency option contracts totaled $325,750. We do not believe that these derivatives present significant credit risks, because the counterparties to the derivatives consist of major financial institutions, and we manage the notional amount of contracts entered into with any one counterparty. We do not enter into derivative financial instruments for speculative or trading purposes. Other than the risk associated with the financial condition of the counterparties, our maximum exposure related to foreign currency forward and option contracts is limited to the premiums paid on purchased options only.

We have both recourse and nonrecourse lease financing arrangements with third-party leasing companies through preexisting relationships with the customers. We sell our products directly to the leasing company, and the lease arrangement is made between our customer and the leasing company. Under the terms of recourse leases, which are generally three years or less, we remain liable for the aggregate unpaid remaining lease payments to the third-party leasing company in the event that any customers default. For these recourse arrangements, revenues on the sale of our product to the leasing company are deferred and recognized into income as payments to the leasing

company come due. As of October 27, 2006 and October 28, 2005, the maximum recourse exposure under such leases totaled approximately $8,543 and $10,402, respectively. Under the terms of the nonrecourse leases, we do not have any continuing obligations or liabilities. To date, we have not experienced significant losses under this lease financing program.

From time to time, we have committed to purchase various key components used in the manufacture of our products. We establish accruals for estimated losses on purchased components for which we believe it is probable that they will not be utilized in future operations. To the extent that such forecasts are not achieved, our commitments and associated accruals may change.

During the quarter, two shareholder derivative lawsuits were filed against various of our officers and directors and naming us as a nominal defendant. The suits allege improper practices relating to the timing of stock option granting. Management believes that the claims are without merit and intends to defend the actions vigorously.

In addition, we are subject to various legal proceedings and claims which may arise in the normal course of business. While the outcome of these legal matters is currently not determinable, we do not believe that any current litigation or claims will have a material adverse effect on our business, cash flow, operating results, or financial condition.

We are currently undergoing federal income tax audits in the U.S. and several foreign tax jurisdictions. The rights to some of our intellectual property (“IP”) are owned by certain of our foreign subsidiaries, and payments are made between foreign and U.S. tax jurisdictions relating to the use of this IP. Recently, some other companies have had their foreign IP arrangements challenged as part of an examination. Our management does not believe, based upon information currently known to us, that the final resolution of any of our audits will have a material adverse effect upon our consolidated financial position and the results of operations and cash flows. However, if upon the conclusion of these audits the ultimate determination of our taxes owed in any of these tax jurisdictions is for an amount in excess of the tax provision we have recorded or reserved for, our overall effective tax rate may be adversely impacted.

16.   Subsequent Event

On November 8, 2006, we entered into a definitive agreement to acquire Topio, Inc. (“Topio”), a privately held Santa Clara, California-based company for approximately $160,000 in cash. The acquisition is expected to close in December 2006, subject to customary closing conditions.

Second Quarter Fiscal 2007 Overview

During the second quarter and first six months of fiscal 2007, our revenue grew year over year and our products have gained market acceptance. We continued to gain momentum through new product introductions in our high-end, midrange, NearStore Virtual Tape Library (“VTL”), and Decru^®products and broadened distribution capabilities. We maintained our leadership position in the iSCSI and network-attached storage markets and showed growth in the Fibre Channel SAN market. Revenue growth occurred across all major geographies. The net increase in revenues year over year was attributable to increased software licenses and software subscriptions, increased service revenue, and an expanded portfolio with new products and solutions for the enterprise customers, and was partially offset by lowercost-per-megabyte disks, and a decline in shipments and lower average selling prices of our older generation products.

Revenue growth in the first quarter and first six months of fiscal 2007 has occurred, while the market for our storage products and solutions remains competitive, with downward pricing pressures that could negatively impact our future revenue growth rate and our future gross margins. We anticipate and continue to experience further price declines per petabyte for our products, which may have an adverse impact on our future gross margins if not offset by favorable software mix and higher average selling prices associated with new products. According to International Data Corporation’s (IDC’s) Worldwide Disk Storage Systems2006-2010 Forecast and Analysis, May 2006, IDC predicts that the average dollar per petabyte (PB) will drop from $8.53/PB in 2006 to $1.85/PB in 2010. At the same time, we also expect our future gross margins to be negatively affected by factors such as global service investment cost, competition, indirect sales including OEM, and high disk content, partially offset by new product introductions, and enhancements and product and add-on software mix.

We experienced a continued decline in revenue generated from the older FAS 900 series systems, which was more than offset by our new product lines. Units shipped of the FAS 3000 increased 77.1% and 174.1% for the second quarter and the first six months of fiscal 2007, respectively, compared to the same periods in the prior fiscal year. The average capacity on revenue units of the FAS 3000 series increased almost 100.3% and 97.2% for the second quarter and the first six months of fiscal 2007, respectively, compared to the same periods in the prior fiscal year. Units of the NearStore R200 also declined as customers moved to ATA-based FAS 3000 units for increased performance. We expect revenue from the FAS 3000 and FAS 6000 series to increase and revenue from the FAS 900 series and NearStore R200 series to decline in fiscal 2007. We recently announced the availability of our new Data ONTAP GX operating system, our next-generation operating system, which combines the global namespace functionality of SpinOS (acquired through the Spinnaker Networks^®acquisition) with the key data management, performance, and high-availability features of Data ONTAP 7G. Coupled with the new high-end FAS 6000and/or FAS 3000 systems, we believe that high-performance computing (HPC) customers can leverage the clustered file system technology inherent in Data ONTAP GX to achieve higher performance and scalability.

On September 11, 2006, we completed the sale of certain NetCache assets to Blue Coat Systems Inc. (“Blue Coat”). As we completed the NetCache transaction in the current quarter, NetCache customers made their final purchases and renewals of their service contracts with us. NetCache contributed 3.0% of total revenue for both the three-month and six-month periods ended October 27, 2006, compared to 3.5% and 3.4%, respectively, for the same periods in the prior year. Revenue contribution from NetCache will decline next quarter, and all future revenue will be in the form of deferred revenue from our balance sheet as we continue to support our existing customers for the life of their service contracts.

During the second quarter of fiscal 2007, our total storage shipped increased to 74.2 petabytes, a 101.5% increase from the 36.8 petabytes shipped in the same quarter a year ago. During the first six months of fiscal 2007, our total storage shipped increased to 146.9 petabytes, a 103.4% increase from the 72.3 petabytes shipped in the same period a year ago. Data protection, disaster recovery, archival, and compliance requirements all contributed to the increase in petabytes shipped, particularly in ATA drives. ATA drives accounted for 58.5% of the second quarter fiscal 2007 increase, increasing to 52.1% of total petabytes shipped from 45.6% in the same prior year period. ATA drives accounted for 59.6% of the increase for the first six months of fiscal 2007, increasing to 53.2% of total petabytes shipped from 46.5% in the same prior year period.

We believe that our strategic investments are targeted at some of the strongest growth areas of the storage market, such as modular storage, archive and compliance, data protection, data classification, data discovery, data

25

migration, data permanence, data security and privacy, iSCSI, and grid computing. However, if any storage market trends and emerging standards on which we are basing our assumptions do not materialize as anticipated, our business could be materially adversely affected.

Continued revenue growth depends on the introduction and market acceptance of our new products. We believe that our new emerging products such as Decru and Virtual Tape Library will further expand our market opportunity. The recently announced Topio acquisition will continue to expand our heterogeneous data protection portfolio. Topio will also enable us to expand our presence in the data center with Fibre Channel SAN by helping accelerate migration of customers using legacy storage systems onto NetApp^® SAN storage systems. We plan to broaden our total addressable market and extend our product lines into adjacent spaces. If we fail to introduce new products in a timely manner or to successfully integrate acquired technology into our existing architecture, or if there is no or reduced demand for these or our current products, we may experience a decline in revenue. We plan to invest in the people, processes, and systems necessary to best optimize our revenue growth and long-term profitability. However, we cannot assure you that such investments will achieve our financial objectives.

Second Quarter Fiscal 2007 Financial Performance

•  Our revenues for the three-month period ended October 27, 2006 were $652.5 million, a 35.1% increase over the same period a year ago. Our revenues for the six-month period ended October 27, 2006 were $1,273.8 million, a 36.8% increase over the same period a year ago. Our revenue growth was driven by the adoption of our enterprise storage products, the FAS 3000 and FAS 6000 series, NearStore VTL, and the Decru security and encryption solutions.

•  Our overall gross margins decreased to 61.5% and 60.8%, respectively, in the three-month and six-month periods ended October 27, 2006, from 61.9% and 61.5%, respectively, in the same periods a year ago. The decline in our gross margin was primarily attributable to the impact of the adoption of Statement of Financial Accounting Standards (“SFAS”) No. 123R and the related stock compensation expenses, partially offset by a higher add-on software mix, favorable production costs, and improved services margins.

•  Cash, cash equivalents, and short-term investments increased to $1,379.4 million as of October 27, 2006, compared to $1,322.9 million as of April 30, 2006, due primarily to cash generated from operations and $23.9 million cash received from the sale of certain NetCache assets, partially offset by cash used to repurchase our common stock of $363.9 million. Days sales outstanding decreased to 56 days as of October 27, 2006, compared to 63 days as of April 30, 2006, reflecting more linear shipments. Inventory turns were 17.3 times and 14.7 times as of October 27, 2006 and April 30, 2006, respectively, reflecting higher inventory at fiscal 2006 year end associated with the new FAS 6000 launch. Deferred revenue increased to $818.6 million as of October 27, 2006, from $681.5 million reported as of April 30, 2006, due to higher software subscription and service billings attributable to an increase in larger enterprise customers. Capital purchases of plant, property, and equipment for the six-month periods ended October 27, 2006 and October 28, 2005 were $76.0 million and $63.0 million, respectively, reflecting continued capital investment to meet our business growth.

Critical Accounting Estimates and Policies

Our discussion and analysis of financial condition and results of operations are based upon our Consolidated Financial Statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of such statements requires us to make estimates and assumptions that affect the reported amounts of revenues and expenses during the reporting period and the reported amounts of assets and liabilities as of the date of the financial statements. Our estimates are based on historical experience and other assumptions that we consider to be appropriate in the circumstances. However, actual future results may vary from our estimates.

We believe that the following accounting policies are “critical” as defined by the Securities and Exchange Commission, in that they are both highly important to the portrayal of our financial condition and results, and require difficult management judgments and assumptions about matters that are inherently uncertain. We also have other important policies, including those related to derivative instruments and concentration of credit risk. However,

26

these policies do not meet the definition of critical accounting policies because they do not generally require us to make estimates or judgments that are difficult or subjective. These policies are discussed in Note 3 to the Consolidated Financial Statements accompanying this Quarterly Report onForm 10-Q.

We believe the accounting policies described below are the ones that most frequently require us to make estimates and judgments, and therefore are critical to the understanding of our results of operations:

•  Revenue recognition and allowances

•  Valuation of goodwill and intangibles

•  Accounting for income taxes

•  Inventory write-downs

•  Restructuring accruals

•  Impairment losses on investments

•  Accounting for stock-based compensation

•  Loss contingencies

Revenue Recognition and Allowances

We apply the provisions of Statement of Position (“SOP”)No. 97-2,Software Revenue Recognition, and related interpretations to our product sales, both hardware and software, because our software is essential to the performance of our hardware. We recognize revenue when:

•  Persuasive evidence of an arrangement exists:  It is our customary practice to have a purchase orderand/or contract prior to recognizing revenue on an arrangement from our end users, customers, value-added resellers, or distributors.

•  Delivery has occurred:  Our product is physically delivered to our customers, generally with standard transfer terms such as FOB origin. We typically do not allow for restocking rights with any of ourvalue-added resellers or distributors. Products shipped with acceptance criteria or return rights are not recognized as revenue until all criteria are achieved. If undelivered products or services exist that are essential to the functionality of the delivered product in an arrangement, delivery is not considered to have occurred.

•  The fee is fixed or determinable:  Arrangements with payment terms extending beyond our standard terms, conditions and practices are not considered to be fixed or determinable. Revenue from such arrangements is recognized as the fees become due and payable. We typically do not allow for price-protection rights with any of our value-added resellers or distributors.

•  Collection is probable:  Probability of collection is assessed on acustomer-by-customer basis. Customers are subjected to a credit review process that evaluates the customers’ financial position and ultimately their ability to pay. If it is determined at the outset of an arrangement that collection is not probable based upon our review process, revenue is recognized upon cash receipt.

Our multiple element arrangements include our systems and generally may also include one or more of the following undelivered elements: installation services, software subscriptions, premium hardware maintenance and storage review services. If the arrangement contains both software-related and non-software-related elements, we allocate revenue to the non-software elements based on objective and reliable evidence of fair value in accordance with Emerging Issues Task Force (“EITF”)00-21,Revenue Arrangements with Multiple Deliverables. Non-software elements are items for which the functionality of the software is not essential to its performance; the non-software-related elements in our arrangements may consist of storage optimization reviews (which are sold only within a bundled service offering that also contains software-related services), technical consultingand/or installation services. For undelivered software-related elements, we apply the provisions ofSOP 97-2 and

27

determine fair value of these undelivered software-related elements based on vendor-specific objective evidence which for us consists of the prices charged when these services are sold separately.

For arrangements with multiple elements, we recognize as revenue the difference between the total arrangement price and the greater of fair value or stated price for any undelivered elements (“the residual method”).

Our software subscriptions entitle our customers to receive unspecified product upgrades and enhancements on awhen-and-if-available basis, bug fixes, and patch releases. Premium hardware maintenance services include contracts for technical support and minimum response times. Revenue from software subscriptions and premium hardware maintenance services is recognized ratably over the contractual term, generally one to three years; standard hardware warranty costs are considered an obligation under SFAS No. 5,Accounting for Contingencies, and are expensed to cost of revenues when revenue is recognized. We also offer extended service contracts (which may include standard warranty as well as premium hardware maintenance) at the end of the warranty term; revenues from these contracts are recognized ratably over the contract term. When storage optimization reviews are sold as a bundled element with our software subscriptions and premium hardware maintenance services, the revenue is recognized ratably over the contract term. We typically sell technical consulting services separately from any of our other revenue elements, either on a time and materials basis or for fixed price standard projects; we recognize revenue for these services as they are performed. Revenue from hardware installation services is recognized at the time of delivery and any remaining costs are accrued, as the remaining undelivered services are considered to be inconsequential and perfunctory.

If vendor-specific evidence cannot be obtained to determine fair value of the undelivered elements, revenue from the entire arrangement would be deferred and recognized as these elements are delivered. This would have a material effect on the timing of product revenues.

We record reductions to revenue for estimated sales returns at the time of shipment. Sales returns are estimated based on historical sales returns, current trends, and our expectations regarding future experience. Reductions to revenue associated with sales returns include consideration of historical sales levels, the timing and magnitude of historical sales returns, and a projection of this experience into the future. We monitor and analyze the accuracy of sales returns estimates by reviewing actual returns and adjust them for future expectations to determine the adequacy of our current and future reserve needs. Our reserve levels have been sufficient to cover actual returns and have not required material changes in subsequent periods. While we currently have no expectations for significant changes to these reserves, if actual future returns and allowances differ from past experience, additional allowances may be required.

We also maintain a separate allowance for doubtful accounts for estimated losses based on our assessment of the collectibility of specific customer accounts and the aging of the accounts receivable. We analyze accounts receivable and historical bad debts, customer concentrations, customer solvency, current economic and geographic trends, and changes in customer payment terms and practices when evaluating the adequacy of current and future allowance. In circumstances where we are aware of a specific customer’s inability to meet its financial obligations to us, a specific allowance for bad debt is estimated and recorded, which reduces the recognized receivable to the estimated amount we believe will ultimately be collected. We monitor and analyze the accuracy of allowance for doubtful accounts estimate by reviewing past collectibility and adjust it for future expectations to determine the adequacy of our current and future allowance. Our reserve levels have generally been sufficient to cover credit losses. Our allowance for doubtful accounts as of October 27, 2006 was $2.6 million, compared to $2.4 million as of April 30, 2006. During the year ended April 30, 2006, we reduced our reserve by $1.5 million due to overall improvement in our collections history. However, if the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required.

Valuation of Goodwill and Intangibles

Identifiable intangible assets are amortized over time, while in-process research and development is recorded as a charge on the date of acquisition and goodwill is capitalized, subject to periodic review for impairment. Accordingly, the allocation of the acquisition cost to identifiable intangible assets has a significant impact on our future operating results. The allocation process requires extensive use of estimates and assumptions, including estimates of future cash flows expected to be generated by the acquired assets. Should conditions be different than

28

management’s current assessment, material write-downs of the fair value of intangible assets may be required. We periodically review the estimated remaining useful lives of our other intangible assets. In addition, a reduction in the estimate of remaining useful life could result in accelerated amortization expense or a write-down in future periods. As such, any future write-downs of these assets would adversely affect our gross and operating margins. We currently do not foresee changes to useful lives or write-downs to these assets.

Under our accounting policy we perform an annual review in the fourth quarter of each fiscal year, or more often if indicators of impairment exist. Triggering events for impairment reviews may be indicators such as adverse industry or economic trends, restructuring actions, lower projections of profitability, or a sustained decline in our market capitalization. Evaluations of possible impairment and, if applicable, adjustments to carrying values require us to estimate, among other factors, future cash flows, useful lives, and fair market values of our reporting units and assets. When we conduct our evaluation of goodwill, the fair value of goodwill is assessed using valuation techniques that require significant management judgment. Should conditions be different from management’s last assessment, significant write-downs of goodwill may be required. In fiscal 2006, we performed such evaluation and found no impairment. However, any future write-downs of goodwill would adversely affect our operating margins. As of October 27, 2006, our assets included $486.4 million in goodwill. See Note 8, “Goodwill and Purchased Intangible Assets,” to our Condensed Consolidated Financial Statements.

During fiscal 2006, we adjusted goodwill by $3.5 million and $2.1 million relating to the tax benefits associated with the subsequent exercise of previously vested assumed Spinnaker and Decru options, respectively. Estimated future adjustments to goodwill related to the tax benefits associated with the subsequent exercise of previously vested assumed options by previous acquisitions are approximately $8.4 million, subject to future cancellations relating to employee terminations. During the second quarter of fiscal year 2007, we recorded a reduction of goodwill for $1.2 million in connection with the divestiture of certain NetCache assets.

Accounting for Income Taxes

The determination of our tax provision is subject to judgments and estimates due to operations in several tax jurisdictions outside the U.S. Earnings derived from our international business are generally taxed at rates that are lower than U.S. rates, resulting in a reduction of our effective tax rate. The ability to maintain our current effective tax rate is contingent upon existing tax laws in both the U.S. and the respective countries in which our international subsidiaries are located. Future changes in domestic or international tax laws could affect the continued realization of the tax benefits we are currently receiving and expect to receive from international business. In addition, a decrease in the percentage of our total earnings from our international business or in the mix of international business among particular tax jurisdictions could increase our overall effective tax rate. While most of our profits are earned in foreign jurisdictions with income tax rates generally lower than the combined U.S. federal and state income tax rates, judgment must be made with respect to other income tax provisions estimates, such as R&D tax credits and valuation allowances against deferred tax assets, primarily those set up for net operating losses and income tax credits.

We account for income taxes in accordance with SFAS No. 109,“Accounting for Income Taxes.”SFAS No. 109 requires that deferred tax assets and liabilities be recognized for the effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. SFAS No. 109 also requires that deferred tax assets be reduced by a valuation allowance if it is more likely than not that some or all of the deferred tax asset will not be realized. We have provided a valuation allowance of $386.8 million as of October 27, 2006, compared to $431.2 million as of April 30, 2006 on certain of our deferred tax assets related to net operating loss carryforwards, conditional royalty carryforwards, and tax credit carryforwards attributable to the exercise of employee stock options, because, under SFAS No. 123R, such amounts should not be realized until they result in a reduction of taxes payable; there was no impact from the adoption of SFAS No. 123R on deferred taxes, as we had used a similar methodology for recording our valuation allowance for these amounts in prior years. The reversal of $44.4 million in the valuation allowance during the first six months of fiscal year 2007 is due to the recognition of certain tax attributes against which a valuation allowance was previously applied. Of the $44.4 million valuation allowance reversal, approximately $3.5 million relates to the utilization of capital loss carryovers applied against the gain from the sale of NetCache, while the remainder relates to the utilization of net operating loss carryovers generated from stock option exercises.

29

We based our provision for income taxes on the expected tax treatment of transactions recorded in our financial statements. In determining our provision for income taxes, we interpret tax legislation in a number of jurisdictions. The provisions for income taxes have not changed significantly from our estimates. Further tax provision adjustments are not expected, but are possible in the event that our interpretation of tax legislation differs from that of the tax authorities.

We are currently undergoing federal income tax audits in the U.S. and several foreign tax jurisdictions. The rights to some of our intellectual property (“IP”) are owned by certain of our foreign subsidiaries, and payments are made between foreign and U.S. tax jurisdictions relating to the use of this IP. Recently, some other companies have had their foreign IP arrangements challenged as part of an examination. Our management does not believe, based upon information currently known to us, that the final resolution of any of our audits will have a material adverse effect upon our consolidated financial position and the results of operations and cash flows. However, if upon the conclusion of these audits the ultimate determination of our taxes owed in any of these tax jurisdictions is for an amount in excess of the tax provision we have recorded or reserved for, our overall effective tax rate may be adversely impacted.

Beginning with the fiscal year 2007 implementation of SFAS No. 123R, we may experience adverse impacts to future years’ effective tax rates in the event that our APIC pool as of the beginning of fiscal year 2007 is not sufficient to cover the impact of future stock compensation shortfalls.

Inventory Write-Downs

Our inventories net balance was $56.8 million as of October 27, 2006, compared to $64.5 million as of April 30, 2006. Inventories are stated at the lower of cost(first-in, first-out basis) or market. We perform an in-depth excess and obsolete analysis of our inventory based upon assumptions about future demand and market conditions. We adjust the inventory value based on estimated excess and obsolete inventories determined primarily by future demand forecasts. Although we strive for accuracy in our forecasts of future product demand, any significant unanticipated changes in demand or technological developments could have a significant impact on the value of our inventory and commitments, and on our reported results. If actual market conditions are less favorable than those projected, additional write-downs and other charges against earnings may be required. If actual market conditions are more favorable, we may realize higher gross margins in the period when the written-down inventory is sold. During the past few years, our inventory reserves have generally been sufficient to cover excess and obsolete exposure and have not required material changes in subsequent periods.

We record purchase commitment liabilities with our contract manufacturers and suppliers as a result of changes in demand forecasts or as we transition our products. As of October 27, 2006, we did not have purchase commitment liabilities under such arrangements.

We engage in extensive, ongoing product quality programs and processes, including actively monitoring and evaluating the quality of our component suppliers. We also provide for the estimated cost of known product failures based on known quality issues when they arise. Should actual cost of product failure differ from our estimates, revisions to the estimated liability would be required.

We are subject to a variety of federal, state, local, and foreign environmental regulations relating to the use, storage, discharge and disposal of hazardous chemicals used during our manufacturing process or requiring design changes or recycling of products we manufacture. We will continue to monitor our environmental compliance and could incur higher costs, including additional reserves for excess component inventory.

Restructuring Accruals

In fiscal 2002, as a result of continuing unfavorable economic conditions and a reduction in IT spending rates, we implemented two restructuring plans, which included reductions in our workforce and a consolidation of our facilities. In fiscal 2006, we implemented the third restructuring plan related to the move of our global service center operations. In determining restructuring charges, we analyze our future business requirements in order to properly align and manage our business commensurate with our future revenue levels.

30

Our restructuring costs, and any resulting accruals, involve significant estimates made by management using the best information available at the time the estimates are made, some of which may be provided by third parties. In recording severance reserves, we accrue a liability when the following conditions have been met: employees’ rights to receive compensation are attributable to employees’ services already rendered; the obligation relates to rights that vest or accumulate; payment of the compensation is probable; and the amount can be reasonably estimated. In recording the facilities lease restructuring reserve, we make various assumptions, including the time period over which the facilities are expected to be vacant, expected sublease terms, expected sublease rates, anticipated future operating expenses, and expected future use of the facilities.

Our estimates involve a number of risks and uncertainties, some of which are beyond our control, including future real estate market conditions and our ability to successfully enter into subleases or lease termination agreements with terms as favorable as those assumed when arriving at our estimates. We regularly evaluate a number of factors to determine the appropriateness and reasonableness of our restructuring and lease loss accruals, including the various assumptions noted above. If actual results differ significantly from our estimates, we may be required to adjust our restructuring and lease loss accruals in the future. We estimated our facility and severance restructuring reserve to be $2.4 million as of October 27, 2006. Our fiscal 2006 facility restructuring reserve included a $1.0 million reduction related to the execution of a new sublease agreement for our Tewksbury facility net of related cost.

Impairment Losses on Investments

As of October 27, 2006, our short-term investments have been classified as“available-for-sale” and are carried at fair value. There have been no significant declines in fair value of investments that are considered to beother-than-temporary, for any of the three years in the period ended October 27, 2006. The fair value of ouravailable-for-sale investment reflected in the Consolidated Balance Sheets was $1,045.8 million and $1,102.8 million as of October 27, 2006 and April 30, 2006, respectively. We have not identified any of these declines to be other than temporary, as market declines of our investments have been caused by interest rate changes and were not due to credit worthiness. Because we have the ability and intent to hold these investments until maturity, we would not expect any significant decline in value of our investments caused by market interest rate changes.

All of ouravailable-for-sale investments and non-marketable equity securities are subject to a periodic impairment review. Investments are considered to be impaired when a decline in fair value is judged to beother-than-temporary. This determination requires significant judgment. For publicly traded investments, impairment is determined based upon the specific facts and circumstances present at the time, including factors such as current economic and market conditions, the credit rating of the security’s issuer, the length of time an investment’s fair value has been below our carrying value, and our ability and intent to hold investments to maturity. If an investment’s decline in fair value, caused by factors other than changes in interest rates, is deemed to beother-than-temporary, we would reduce its carrying value to its estimated fair value, as determined based on quoted market prices or liquidation values. We have no impairment losses on ouravailable-for-sale investments for the three- and six-months periods ended October 27, 2006 and October 28, 2005.

For non-marketable equity securities, the impairment analysis requires the identification of events or circumstances that would likely have a significant adverse effect on the fair value of the investment, including, revenue and earnings trends, overall business prospects, limited capital resources, limited prospects of receiving additional financing, limited prospects for liquidity of the related securities and general market conditions in the investees’ industry. Our investments in privately held companies were $10.2 million and $11.0 million as of October 27, 2006 and April 30, 2006, respectively. For the second quarter of fiscal 2007, we recorded an impairment of $2.0 million for an investment in a privately held company. We have no impairment losses on our investments in privately held companies for the three- and six-months periods ended October 28, 2005.

Accounting for Stock-Based Compensation

We adopted SFAS No. 123R,Share-Based Payment, using the Black-Scholes option pricing model to value our employee stock options. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model, and is not remeasured as a result of subsequent stock price fluctuations. Option pricing

31

models require the input of highly subjective assumptions, including the expected stock price volatility, expected life, and forfeiture rate. We have chosen to base our estimate of future volatility using the implied volatility of traded options to purchase the Company’s common stock as permitted by Staff Accounting Bulletin (“SAB”) No. 107. As of May 1, 2006, the contractual life of our stock options has been shortened to seven years from ten years for options issued on or after this date, and to the extent that the shorter life changes employees’ exercise behavior, it may change the expected term of an option going forward. SFAS No. 123R requires us to use estimated forfeitures, and therefore the adoption of SFAS No. 123R could have a material impact on the timing of and, based on the accuracy of estimates of future actual forfeitures, the amount of stock compensation expense. Any changes in these highly subjective assumptions may significantly impact the stock compensation expense for the future. Likewise, the shortening of the contractual life of our options could change the estimated exercise behavior in a manner other than currently expected.

We currently estimate that the impact of adopting SFAS No. 123R on our fiscal year ending April 30, 2007 will be between $0.33 and $0.40 per share.

Loss Contingencies

We are subject to the possibility of various loss contingencies arising in the course of business. We consider the likelihood of the loss or impairment of an asset or the incurrence of a liability as well as our ability to reasonably estimate the amount of loss in determining loss contingencies. An estimated loss contingency is accrued when it is probable that a liability has been incurred or an asset has been impaired and the amount of loss can be reasonably estimated. In the three- and six-month periods ended October 27, 2006 and October 28, 2005, we did not identify or accrue for any loss contingencies. We regularly evaluate current information available to us to determine whether such accruals should be adjusted.

New Accounting Standards

See Note 14 of the Condensed Consolidated Financial Statements for a full description of recent accounting pronouncements, including the respective expected dates of adoption and effects on results of operations and financial condition.

Discussion and Analysis of Results of Operations

Total Revenues — Total revenues increased by 35.1% to $652.5 million for the three-month period ended October 27, 2006, from $483.1 million for the three-month period ended October 28, 2005. Total revenues increased by 36.8% to $1,273.8 million for the six-month period ended October 27, 2006, from $931.5 million for the six-month period ended October 28, 2005.

Product Revenues — Product revenues increased by 30.9% to $481.3 million for the three-month period ended October 27, 2006, from $367.7 million for the three-month period ended October 28, 2005. Product revenues increased by 33.6% to $946.9 million for the six-month period ended October 27, 2006, from $708.6 million for the six-month period ended October 28, 2005.

Product revenues were impacted by the following factors:

•  increased revenues from our current product portfolio. Product revenue grew $112.6 million for the second quarter of fiscal 2007 as compared to the same period in the prior year, with a $110.6 million increase due to unit volume and an increase of $2.0 million due to price and configuration on existing products. Product revenue grew $238.2 million for the first six months of fiscal 2007 as compared to the same period in the prior year, with a $248.3 million increase due to unit volume and partially offset by a decrease of $11.0 million due to price and configuration of existing products. Price changes, volumes, and product model mix can have an effect on changes in product revenues; the impact on these forces is significantly affected by the configuration of systems shipped

•  new products generated $66.1 million and $110.5 million in the second quarter and first six months of fiscal 2007, respectively, primarily driven by FAS 6000, Decru and the NearStore VTL products

•  increased enterprise penetration in primary and secondary storage, i.e., enterprise data centers, data protection, disaster recovery, archival, and compliance requirements contributed to the increase in petabytes shipped. Systems shipped with ATA drives increased to 52.1% of total petabytes shipped in the second

33

quarter of fiscal 2007, from 45.6% in the same quarter a year ago. For the first six months of fiscal 2007 and 2006, systems shipped with ATA drives accounted for 53.2% and 46.5% of total petabytes shipped, respectively. The new 500 gigabit ATA drives, introduced in the fourth quarter of fiscal 2006, contributed 39.0% and 35.1% of the total capacity shipped in the second quarter and the first six months of fiscal 2007, respectively

•  increased sales of add-on storage driven by incremental storage demand as some customers began to approach their maximum utilization point on their initial FAS 3000 configurations

•  increased sales through indirect channels, including sales through our resellers, distributors and OEM partners, represented 58.9% and 57.3% of total revenues for the three- and six-month periods ended October 27, 2006, respectively, and 60.3% and 55.5% of total revenues for the three- and six-month periods ended October 28, 2005, respectively

•  lower-cost-per-megabyte storage which is a significant component of our hardware costs. As performance has improved on these devices, the related sales price we can charge per megabyte of storage has decreased. Our average revenue per petabyte (PB) has decreased from $7.36/PB and $7.65/PB, in the second quarter and the first six months of calendar 2005, respectively, to $4.26/PB and $4.67/PB in the second quarter and the first six months of calendar 2006, respectively

•  revenues for our older products declined by $87.3 million and $194.1 million in the second quarter and first six months of fiscal 2007, respectively, compared to the same periods in the prior year. This decrease in revenue was primarily due to a decline in revenue generated by FAS 900 series systems by 70.9% and 63.5%, respectively, in the second quarter and first six months of fiscal 2007. Unit sales of FAS 900 series systems also declined by 73.8% and 66.2%, respectively, in the second quarter and first six months of fiscal 2007. NearStore R200 systems revenue decreased by 53.2% and 49.3%, respectively, in the second quarter and first six months of fiscal 2007. NearStore R200 systems units decreased by 62.6% and 59.0%, respectively, in the second quarter and first six months of fiscal 2007. In addition, revenue also declined by $4.7 million and $5.8 million, respectively, in the second quarter and first six months of fiscal 2007 due to products that we no longer ship in the second quarter and first six months of fiscal 2007.

Our systems are highly configurable because of customer requirements in the open systems storage markets that we serve. As a result, the wide variation in customized configuration can significantly impact revenue, cost of revenues, and gross margin performance. Price changes, volumes, and product model mix can have an effect on changes in product revenues; the impact on these forces is significantly affected by the configuration of systems shipped.

While revenues generated from IBM and Decru accounted for 3.0% and 2.0% of total revenue, respectively, for the three-month period ended October 27, 2006, and 2.9% and 2.2% of total revenue, respectively, for the six-month period ended October 27, 2006, we cannot assure you that IBM and Decru will continue to contribute meaningful revenue in future quarters. We also cannot assure you that we will be able to maintain or increase market demand for our products.

Software Subscriptions Revenues — Software subscriptions revenues increased by 44.2% to $82.3 million for the three-month period ended October 27, 2006, from $57.1 million for the three-month period ended October 28, 2005, due primarily to a larger installed base of renewals, upgrades, and an increased number of new enterprise customers. Software subscriptions revenues increased by 41.8% to $157.1 million for the six-month period ended October 27, 2006, from $110.8 million for the six-month period ended October 28, 2005, due primarily to a larger installed base of renewals, upgrades, and an increased number of new enterprise customers. Software subscriptions revenues represented 12.6% and 12.3% of total revenues for the three- and six-month periods ended October 27, 2006, and 11.8% and 11.9% of total revenues for the three- and six-month periods ended October 28, 2005.

Service Revenues — Service revenues, which include hardware support, professional services, and educational services, increased by 52.7% to $89.0 million for the three-month period ended October 27, 2006, from $58.3 million in the three-month period ended October 28, 2005. Service revenues increased by 51.6% to $169.8 million in the six-month period ended October 27, 2006, from $112.1 million in the six-month period ended October 28, 2005.

34

The increase in absolute dollars was due to the following factors:

•  professional service revenue increased by 55.2% in the three-month period ended October 27, 2006 compared to the same period ended a year ago, and increased by 52.6% in the six-month period ended October 27, 2006 compared to the same period a year ago

•  service maintenance contracts increased by 51.5% in both the first quarter and the first six months of fiscal 2007 compared to the same periods a year ago

•  an increasing number of enterprise customers, which typically purchase more complete and generally longer-term service packages than our non-enterprise customers

•  a growing installed base resulted in new customer support contracts in addition to support contract renewals by existing customers

While it is an element of our strategy to expand and offer a more comprehensive, global enterprise support and service solution, we cannot assure you that service revenue will grow at the current rate in the remainder of fiscal 2007.

A large portion of our service revenues is initially deferred and, in most cases, recognized ratably over the service obligation periods, which are typically one to three years. Service revenues represented 13.6% and 13.3% of total revenues for the three- and six-month periods ended October 27, 2006, respectively, and 12.1% and 12.0% of total revenues for the three- and six-month periods ended October 28, 2005, respectively.

International total revenues — International total revenues (including United States exports) increased by 36.0% and 41.6% for the three- and six-month periods ended October 27, 2006, respectively, as compared to the same periods in fiscal 2006. Total revenues from Europe were $191.4 million and $386.3 million, or 29.3% and 30.3% of total revenues, respectively, for the three- and six-month periods ended October 27, 2006, compared to $140.3 million and $267.2, or 29.0% and 28.7% of total revenues, for the three- and six-month periods ended October 28, 2005. Total revenues from Asia were $72.9 million and $146.1 million, or 11.2% and 11.5% of total revenues, respectively, for the three- and six-month periods ended October 27, 2006, compared to $54.1 million $108.8 million, or 11.2% and 11.7% of total revenues, respectively, for the three- and six-month periods ended October 28, 2005. The increase in international sales was primarily driven by the same factors outlined under the Total Revenue discussion, as compared to the same periods in the prior fiscal year. We cannot assure you that we will be able to maintain or increase international revenues in the remainder of fiscal 2007.

Product Gross Margin — Product gross margin decreased to 61.3% for the three-month period ended October 27, 2006, from 62.1% for the same period in fiscal 2006. Product gross margin decreased to 60.5% for the six-month period of fiscal 2007, from 61.8% for the same period in fiscal 2006.

Product gross margin was negatively impacted by:

•  SFAS 123R stock compensation expenses recorded in fiscal 2007

•  sales price reductions due to competitive pricing pressure

•  increased sales through certain indirect channels, which generate lower gross margins than our direct sales in certain geographic regions

•  higher disk content with an expanded storage capacity for the higher-end filers and NearStore systems, as resale of disk drives generates lower gross margin

•  Product gross margin was favorably impacted by:

•  favorable add-on software mix with software licenses increasing by 32.8% and 38.1% in three- and six-month periods ended October 27, 2006 compared to the same periods of fiscal 2006

•  a favorable mix shift to FAS 6000 and V-series products sold as diskless upgrades, which carries higher margin than configured systems

35

•  better disk utilization rates associated with sales of higher-margin management software products like FlexClone^tm and FlexVol^tm that run on the Data ONTAP 7G operating system allowing customers to buy less disk storage

We expect that higher disk content associated with high-end and mid-range storage systems will negatively affect our gross margin in the future if not offset by increases in software revenue and new higher-margin products.

Stock compensation included in cost of product revenues was $1.1 million and $1.7 million for the three- and six-month periods ended October 27, 2006. Amortization of existing technology included in cost of product revenues was $3.9 million and $7.7 million for the three- and six-month periods ended October 27, 2006, respectively, and $2.9 million and $4.1 million for the three- and six-month periods ended October 28, 2005, respectively. Estimated future amortization of existing technology to cost of product revenues will be $7.7 million for the remainder of fiscal 2007, $15.5 million for fiscal year 2008, $14.7 million for fiscal year 2009, $10.3 million for fiscal year 2010, $2.8 million for fiscal year 2011, and none thereafter.

Software Subscriptions Gross Margin — Software subscriptions gross margins increased slightly to 97.0% for the three-month period ended October 27, 2006, from 96.8% for the three-month period ended October 28, 2005. Software subscriptions gross margins increased slightly to 97.0% for the six-month period ended October 27, 2006, from 96.3% for the six-month period ended October 28, 2005.

Service Gross Margin — Service gross margin increased to 29.8% for the three-month period ended October 27, 2006 as compared to 26.5% in the same period in fiscal 2006. Service gross margin increased to 29.1% for the six-month period ended October 27, 2006 as compared to 25.0% in the same period in fiscal 2006. Cost of service revenue increased by 45.8% to $62.5 million for the three-month period ended October 27, 2006, from $42.9 million for the three-month period ended October 28, 2005. Cost of service revenue increased by 43.4% to $120.5 million for the six-month period ended October 27, 2006, from $84.0 million for the six-month period ended October 28, 2005. Stock compensation of $2.5 million and $5.1 million was included in the cost of service revenue for the three- and six-month periods ended October 27, 2006, respectively.

The improvement in service gross margin for the three-month period ended October 27, 2006 compared to the same quarter in fiscal 2006 was primarily due to an increase in services revenue and improved headcount utilization, partially offset by the continued spending in our service infrastructure to support our increasing enterprise customer base. This spending included additional professional support engineers, increased support center activities, and global service partnership programs. Service gross margin will typically be impacted by factors such as timing of technical support service initiations and renewals and additional investments in our customer support infrastructure. In fiscal 2007, we expect service margin to experience some variability over time as we continue to build out our service capability and capacity to support our growing enterprise customers and new products.

Sales and Marketing — Sales and marketing expenses consist primarily of salaries, commissions, advertising and promotional expenses, stock-based compensation, and certain customer service and support costs. Sales and marketing expenses increased 46.7% to $204.3 million for the three-month period ended October 27, 2006, from $139.2 million for the same period a year ago. These expenses were 31.4% and 28.9% of total revenues for the three-month periods ended October 27, 2006 and October 28, 2005, respectively. Sales and marketing expenses increased 44.3% to $399.8 million for the six-month period ended October 27, 2006, from $277.0 million for the same period a year ago. These expenses were 31.4% and 29.8% of total revenues for the six-month periods ended October 27, 2006 and October 28, 2005, respectively. The increase in absolute dollars was attributed to increased commission expenses resulting from increased revenues, higher performance-based payroll expenses due to higher profitability, higher partner program expenses, the continued worldwide investment in our sales and global service organizations associated with selling complete enterprise solutions, and stock compensation expenses recognized under adoption of SFAS No. 123R.

Stock compensation included in sales and marketing expenses for the three- and six-month periods ended October 27, 2006 was $18.7 million and $37.4 million. Deferred compensation expenses related to stock options and restricted stocks assumed in acquisitions was $1.0 million and $1.5 million for the three- and six-month periods ended October 28, 2005. Amortization of Spinnaker trademarks/tradenames and customer contracts/relationships included in sales and marketing expenses was $0.6 million and $0.5 million for the three-month periods ended

36

October 27, 2006 and October 28, 2005, respectively and was $1.2 million and $0.7 million for the six-month periods ended October 27, 2006 and October 28, 2005, respectively. Estimated future amortization of trademarks, tradenames, and customer contracts and relationships included in sales and marketing expenses will be $1.1 million for the remainder of fiscal 2007, $2.2 million for fiscal 2008, 2009, and 2010, $1.3 million for fiscal 2011, and $0.3 million thereafter.

We expect to continue to selectively add sales capacity in an effort to expand domestic and international markets, introduce new products, establish and expand new distribution channels, and increase product and company awareness. We expect to increase our sales and marketing expenses commensurate with future revenue growth.

Research and Development — Research and development expenses consist primarily of salaries and benefits, stock-based compensation, prototype expenses, nonrecurring engineering charges, fees paid to outside consultants, and amortization of capitalized patents.

Research and development expenses increased 55.4% to $90.4 million for the three-month period ended October 27, 2006, from $58.1 million for the same period ended October 28, 2005. These expenses represented 13.8% and 12.0% of total revenues for the second quarters of fiscal 2007 and 2006, respectively. Research and development expenses increased 62.3% to $179.0 million for the six-month period ended October 27, 2006, from $110.3 million for the same period ended October 28, 2005. These expenses represented 14.1% and 11.8% of total revenues for the first six months of fiscal 2007 and 2006, respectively. The increase in research and development expenses was primarily a result of increased headcount, ongoing operating impact of the acquisitions, ongoing support of current and future product development and enhancement efforts, higher performance-based payroll expenses due to higher profitability, and stock-based compensation recognized under adoption of SFAS No. 123R. For both the three- and six-month periods ended October 27, 2006 and October 28, 2005, no software development costs were capitalized.

Stock compensation included in research and development expenses for the three- and six-month periods ended October 27, 2006 was $13.0 million and $26.9 million. Deferred compensation expenses related to stock option and restricted stock assumed in acquisitions was $2.1 million and $3.5 million for the three- and six-month periods ended October 28, 2005. Included in research and development expenses is capitalized patents amortization of $0.5 million and $1.0 million for the three- and six-month periods ended October 27, 2006, respectively, as compared to $0.5 million and $1.0 million for the three- and six-month periods ended October 28, 2005. Based on capitalized patents recorded at October 27, 2006, estimated future capitalized patents amortization expenses for the remainder of fiscal 2007 will be $1.0 million, $2.0 million for fiscal year 2008, $0.5 million in fiscal 2009, $0.2 million in fiscal 2010, and none thereafter.

We believe that our future performance will depend in large part on our ability to maintain and enhance our current product line, develop new products that achieve market acceptance, maintain technological competitiveness, and meet an expanding range of customer requirements. We expect to continuously support current and future product development and enhancement efforts, and to incur prototyping expenses and nonrecurring engineering charges associated with the development of new products and technologies. We intend to continuously broaden our existing product offerings and to introduce new products that expand our solutions portfolio.

We believe that our research and development expenses will increase in absolute dollars for the remainder of fiscal 2007, primarily due to ongoing costs associated with the development of new products and technologies, projected headcount growth, and the operating impact of potential future acquisitions.

General and Administrative — General and administrative expenses increased 61.6% to $35.2 million for the three-month period ended October 27, 2006, from $21.8 million for the same period ended October 28, 2005. These expenses represented 5.4% and 4.5% of total revenues for the three-month periods ended October 27, 2006 and October 28, 2005, respectively. General and administrative expenses increased 57.3% to $67.6 million for the six-month period ended October 27, 2006, from $43.0 million for the same period ended October 28, 2005. These expenses represented 5.3% and 4.7% of total revenues for the six-month periods ended October 27, 2006 and October 28, 2005, respectively. This increase in absolute dollars was primarily due to higher performance-based

37

payroll expenses due to higher profitability and higher headcount growth, higher stock-based compensation recognized under SFAS No. 123R, and higher legal expenses and professional fees for general corporate matters.

We believe that our general and administrative expenses will increase in absolute dollars for the remainder of fiscal 2007 due to projected general and administrative headcount growth. Stock compensation included in general and administrative expenses for the three- and six-month periods ended October 27, 2006 was $7.1 million and $14.3 million, respectively. Deferred compensation expenses related to stock options and restricted stocks assumed in acquisitions was $0.2 million and $0.4 million, respectively, for the three- and six-month periods ended October 28, 2005. Amortization of covenants not to compete included in general and administrative expenses was $0.2 million and $0.5 million for the three- and six-month periods ended October 27, 2006, respectively, as compared to $0.4 million and $1.8 million for the three- and six-month periods ended October 28, 2005, respectively. Estimated future amortization of covenants not to compete relating to our acquisitions will be $0.5 million in the remainder of fiscal 2007, $0.2 million for fiscal year 2008, and none thereafter.

Restructuring Charges — In fiscal 2002, as a result of continuing unfavorable economic conditions and a reduction in IT spending rates, we implemented two restructuring plans, which included reductions in our workforce and consolidations of our facilities. As of October 27, 2006, we have no outstanding balance in our restructuring liability for the first restructuring. The second restructuring related to the closure of an engineering facility and consolidation of resources to the Sunnyvale headquarters. In fiscal 2006, we implemented a third restructuring plan related to the move of our global services center operations from Sunnyvale to our new flagship support center at our Research Triangle Park facility in North Carolina.

Our restructuring estimates are reviewed and revised periodically and may result in a substantial charge or reduction to restructuring expense should different conditions prevail than were anticipated in previous management estimates. Such estimates included various assumptions such as the time period over which the facilities will be vacant, expected sublease terms, and expected sublease rates. During the three-month period ended October 27, 2006, we did not record any reduction in restructuring reserve resulting from change in estimate of our third restructuring plan.

Of the reserve balance at October 27, 2006, $0.5 million was included in other accrued liabilities and the remaining $1.8 million was classified as long-term obligations. The balance of the reserve is expected to be paid by fiscal 2011.

The following analysis sets forth the changes in the restructuring reserve for the three months ended October 27, 2006 (in thousands):

	Facility Accrual			Severance-Related			Total
Reserve balance at April 30, 2005	$	4,503		$	—		$	4,503
Restructuring charges		281			859			1,140
Adjustments		(1,256	)		—			(1,256	)
Cash payments		(862	)		(521	)		(1,383	)
Reserve balance at April 30, 2006	$	2,666		$	338		$	3,004
Restructuring recoveries		—			(74	)		(74	)
Cash payments		(149	)		(82	)		(231	)
Reserve balance at July 28, 2006	$	2,517		$	182		$	2,699
Cash payments		(143	)		(182	)		(325	)
Reserve balance at October 27, 2006	$	2,374		$	—		$	2,374

Gain on sale of assets — We recorded a gain of $25.3 million for the three- and six-months periods ended October 27, 2006 as a result of the sale of certain assets to Blue Coat (see Note 12 of the Condensed Consolidated Financial Statements).

Interest Income — Interest income was $17.5 million and $34.1 million for the three- and six-month periods ended October 27, 2006, respectively, as compared to $9.7 million and $18.7 million for the three- and six-month

38

periods ended October 28, 2005. The increase in interest income was primarily driven by higher average interest rates on our investment portfolio. We expect interest income to increase for fiscal 2007 as a result of higher cash and invested balances in a higher interest-rate portfolio environment.

Interest Expense — Interest expense was $5.2 million and $9.0 million for the three- and six-month periods ended October 27, 2006, respectively, as compared to minimal interest expenses for the three- and six-month periods ended October 28, 2005. The increase in fiscal 2007 was primarily due to interest incurred in connection with our debt.

Other Income (Expense), Net — Other Income (Expense), Net, was $1.9 million and $2.7 million, respectively, for the three- and six-month periods ended October 27, 2006. Other Income (Expense), Net for the second quarter of fiscal 2007 included net exchange gains from foreign currency of $0.2 million and other income of $1.7 million. Other Income (Expense), Net for the first six months of fiscal 2007 included net exchange gains from foreign currency of $0.8 million and other income of $1.9 million. Other Income (Expense), Net, included net exchange losses from foreign currency of $0.2 million and $0.4 million for the three- and six-month periods ended October 28, 2005. We believe thatperiod-to-period changes in foreign exchange gains or losses will continue to be impacted by hedging costs associated with our forward and option activities and forecast variance.

Net Gain (Loss) on Investments — Net gain (loss) on investments included a temporary write-down of $2.0 million related to the impairment of our investment in a privately held company for the three- and six-month periods ended October 27, 2006.

Provision for Income Taxes — For the three- and six-month periods ended October 27, 2006, we applied an annual effective tax rate of 20.2% and 20.9%, respectively, to pretax income versus 15.5% and 16.2%, respectively, for the comparable periods in the prior year. The tax rates for the three- and six-month periods ending October 27, 2006 and October 28, 2005 included discrete income tax provision items. For the three- and six-month periods ending October 27, 2006, a net tax expense of $2.4 million related to the gain on the sale of NetCache was reported as a discrete income tax provision item. For the three- and six-month periods ending October 28, 2005, a tax benefit of $4.6 million related to a R&D tax credit study was reported as a discrete income tax provision item. The increase to the effective tax rate for fiscal year 2007 is also attributable to the impacts of SFAS No. 123R. These rates reflect a favorable foreign tax ruling for our principal European subsidiary. Our estimate of the effective tax rate is based on the application of existing tax laws to current projections of our annual consolidated income, including projections of the mix of income (loss) earned among our entities and tax jurisdictions in which they operate.

Liquidity and Capital Resources

The following sections discuss the effects of changes in our balance sheet and cash flow, contractual obligations and other commercial commitments, stock repurchase program, capital commitments, and other sources and uses of cash flow on our liquidity and capital resources.

Balance Sheet and Operating Cash Flows

As of October 27, 2006, as compared to April 30, 2006, our cash, cash equivalents, and short-term investments increased by $56.5 million to $1,379.4 million. We derive our liquidity and capital resources primarily from our cash flow from operations and from working capital. Working capital increased by $0.2 million to $1,116.2 million as of October 27, 2006, compared to $1,116.0 million as of April 30, 2006.

During the six-month period ended October 27, 2006, we generated cash flows from operating activities of $403.4 million, as compared with $241.4 million in the same period in fiscal 2006. We recorded net income of $141.6 million in the six-month period ended October 27, 2006, as compared to $130.8 million in the same period in fiscal 2006. A summary of the significant changes in noncash adjustments affecting net income is as follows:

•  Stock-based compensation expense was $85.4 million in the six-month period ended October 27, 2006, compared to $5.4 million in the same period a year ago. The increase was attributed to the adoption of SFAS No. 123R.

39

•  Depreciation expense was $39.4 million and $30.1 million in the six-month period ended October 27, 2006 and October 28, 2005, respectively. The increase was due to continued capital expansion to meet our business growth.

•  Amortization of intangibles was $9.4 million and $6.5 million in the six-month period ended October 27, 2006 and October 28, 2005, respectively. The increase was attributed to the Decru acquisition.

•  Gain on sale of certain assets to Blue Coat was $25.3 million in the six-month period ended October 27, 2006.

In addition to net income and noncash adjustments in the six-month period ended October 27, 2006, the primary factors that impacted theperiod-to-period change in cash flows relating to operating activities included the following:

•  An increase in deferred revenues of $137.7 million in the six-month period ended October 27, 2006, due to higher software subscription and service billings attributable to the increase in larger enterprise customers, as well as renewals of existing maintenance agreements in the first quarter of fiscal 2007. The increase in deferred revenue of $85.8 million in the six-month period ended October 28, 2005 was due to higher software subscription and service billings resulting from increased enterprise penetration.

•  Increase in income taxes payable of $12.3 million in the six-month period ended October 27, 2006 was attributed to tax payments of $27.1 million, which included an $18.7 million federal income tax payment made for the fiscal year 2006 tax year relating to the income tax on the foreign dividend repatriation, partially offset by the tax provision of $37.5 million and tax refund of $1.9 million. Income tax payable increased $24.1 million in the six-month period ended October 28, 2005, primarily due to tax provision of $25.3 million, partially offset by tax payments of $3.7 million.

•  Decrease in accounts receivable of $15.4 million in the six-month period ended October 27, 2006 was due to more linear shipments. Increase in accounts receivable of $28.3 million in the six-month period ended October 28, 2005 was due primarily to less linear shipments in the second quarter of fiscal 2006.

•  Net inventory decreased $8.2 million for the six-month period ended October 27, 2006, primarily due to higher inventory at fiscal 2006 year end associated with the new FAS 6000 launch and increased shipments of this product in the second quarter of fiscal 2007. The increase of $13.6 million in the six-month period ended October 28, 2005 was due primarily to ramping up of purchased components in anticipation of revenue growth.

The above factors were partially offset by the effects of:

•  Excess tax benefits of $23.8 million relating to stock-based compensation upon the exercise of stock options.

•  Accrued compensation and related benefits decreased by $6.3 million and $11.1 million in the six-month periods ended October 27, 2006 and October 28, 2005, respectively. The changes for both periods were due to payout of commission and performance-based payroll expenses during the first six months of fiscal 2007 and previously accrued for in fiscal 2006, partially offset by fiscal 2007 accrual for the first six month of fiscal 2007.

We expect that cash provided by operating activities may fluctuate in future periods as a result of a number of factors, including fluctuations in our operating results, shipment linearity, accounts receivable collections, inventory management, and the timing of tax and other payments.

Cash Flows from Investing Activities

Capital expenditures for the six-month period ended October 27, 2006 were $76.0 million as compared to $63.0 million in the same period a year ago. We received net proceeds of $17.0 million and $84.8 million in thesix-month periods ended October 27, 2006 and October 28, 2005, respectively, for net purchases/redemptions ofshort-term investments. We redeemed $52.6 million of restricted investment and its interest income pledged with JP Morgan Chase to repay the Tranche A term loan with JP Morgan Chase. (See Note 5.) Investing activities in thesix-month period ended October 27, 2006 also included new investments in privately held companies of $1.3 million.

In the second quarter of fiscal 2007, we received $23.9 million in cash in connection with the sale of certain assets to Blue Coat. In the first quarter of fiscal 2006, we acquired Alacritus for a purchase price of approximately $13.7 million, including assumed options, cash payments of $11.0 million, and related transaction costs. In the second quarter of fiscal 2006, we acquired Decru for a purchase price of approximately $283.2 million, including assumed options, net cash payments of $41.2 million, and related transaction costs.

Cash Flows from Financing Activities

We used $358.5 million and $172.7 million in the six-month periods ended October 27, 2006 and October 28, 2005, respectively, from net financing activities, which included repayment of debt and sales of common stock related to employee stock transactions net of common stock repurchases. We made a repayment of $106.6 million for our debt during the six-month period ended October 27, 2006. We repurchased 10.8 million and 9.6 million shares of common stock at a total of $363.9 million and $244.6 million during the six-month periods ended October 27, 2006 and October 28, 2005, respectively. Other financing activities provided $92.5 million and $72.5 million in the six-month periods ended October 27, 2006 and October 28, 2005, respectively, from sales of common stock related to employee stock option exercises and employee stock purchases. Tax benefits, related to tax deductions in excess of the compensation cost recognized, of $23.8 million were presented as financing cash flows for the six-month period ended October 27, 2006 in accordance with SFAS No. 123R. During the six-month periods ended October 27, 2006 and October 28, 2005, we withheld $4.3 million and $0.6 million in shares, respectively, from certain employees’ exercised shares of their restricted stock to reimburse for federal, state, and local withholding taxes obligations. The increase in the amounts withheld year over year was due to the release of Decru’s assumed restricted stock units.

The change in cash flow from financing was primarily due to the effects of higher common stock repurchases partially offset by proceeds from the issuance of common stock under employee programs compared to the same period in the prior year. Net proceeds from the issuance of common stock related to employee participation in employee stock programs have historically been a significant component of our liquidity. The extent to which our employees participate in these programs generally increases or decreases based upon changes in the market price of our common stock. As a result, our cash flow resulting from the issuance of common stock related to employee participation in employee stock programs will vary.

Other Factors Affecting Liquidity and Capital Resources

The American Jobs Creation Act of 2004 (“the Jobs Act”) created a one-time incentive for U.S. corporations to repatriate accumulated income earned abroad by providing an 85% dividend-received deduction for certain dividends from certainnon-U.S. subsidiaries. We remitted $18.7 million related to the federal portion of the tax liability during the first six-month period ended October 27, 2006.

For the six-month periods ended October 27, 2006 and October 28, 2005, the income tax benefit associated with dispositions of employee stock transactions was $79.0 million and $16.3 million, respectively. Of the $79.0 million, $37.1 million relates to tax benefits generated from stock option exercises during the six-month period ended October 27, 2006 while the remaining $41.9 million relates to a reduction of accrued income taxes payable due to the utilization of net operating loss carryovers generated from stock options in prior years. If stock option exercise patterns change, we may receive less cash from stock option exercises and may not receive the same level of tax benefits in the future, which could cause our cash payments for income taxes to increase.

On November 8, 2006, we entered into a definitive agreement to acquire Topio, a privately held Santa Clara, California-based company for approximately $160.0 million in cash. The acquisition is expected to close in December 2006, subject to customary closing conditions.

Stock Repurchase Program

At October 27, 2006, $41.7 million remained available for future repurchases. The stock repurchase program may be suspended or discontinued at any time.

41

On November 15, 2006, our Board approved a new stock repurchase program in which up to $800.0 million of additional shares may be purchased.

Debt

In March 2006, we received proceeds from a term loan totaling $300.0 million to finance a foreign dividend repatriation under the Jobs Act. (See Note 5 of the Condensed Consolidated Financial Statements.) The loan repayments of $105.1 million and $88.4 million are due in the remainder of fiscal 2007 and fiscal 2008. This debt was collateralized by restricted investments totaling $189.7 million, as well as certain foreign receivables as of October 27, 2006. In accordance with the payment terms of the loan agreement, interest payments will be approximately $4.2 million and $2.9 million in the remainder of fiscal 2007 and fiscal 2008, respectively. As of October 27, 2006, we are in compliance with the liquidity and leverage ratio as required by the Loan Agreement with the lenders.

Contractual Cash Obligations and Other Commercial Commitments

The following summarizes our contractual cash obligations and commercial commitments at October 27, 2006, and the effect such obligations are expected to have on our liquidity and cash flow in future periods, (in thousands):

For purposes of the above table, contractual obligations for the purchase of goods and services are defined as agreements that are enforceable, legally binding on us, and subject us to penalties if we cancel the agreement. Some of the figures we include in this table are based on management’s estimates and assumptions about these obligations, including their duration, the possibility of renewal or termination, anticipated actions by management and third parties, and other factors. Because these estimates and assumptions are necessarily subjective, the enforceable and legally binding obligations we will actually pay in future periods may vary from those reflected in the table.

Lines of Credit(9)	$	1,983	$	—	$	—	$	—	$	—	$	351	$	2,334

(1) We enter into operating leases in the normal course of business. We lease sales offices, research and development facilities, and other property and equipment under operating leases throughout the U.S. and internationally, which expire through fiscal year 2016. Substantially all lease agreements have fixed payment terms based on the passage of time and contain escalation clauses. Some lease agreements provide us with the

42

	option to renew the lease or to terminate the lease. Our future operating lease obligations would change if we were to exercise these options and if we were to enter into additional operating lease agreements. Facilities operating lease payments exclude the leases impacted by the restructurings. The amounts for the leases impacted by the restructurings are included in subparagraph (6) below. The net increase in the office operating lease payments was primarily due to a new domestic lease executed with a10-year term during the first quarter of fiscal 2007.
(2)	On December 16, 2005, we entered into financing, construction, and leasing arrangements with BNP Paribas LLC (“BNP”) for office space to be located on land currently owned by us in Sunnyvale, California. These arrangements require us to lease our land to BNP for a period of 50 years to construct approximately 190,000 square feet of office space costing up to $38.5 million. After completion of construction, we will pay minimum lease payments, which vary based on London Interbank Offered Rate (“LIBOR”) plus a spread (6.07% at October 27, 2006) on the cost of the facilities. We expect to begin paying lease payments on the completed buildings on September 2007 for a term of five years. We have the option to renew the lease for two consecutive five-year periods upon approval by BNP.
	Upon expiration (or upon any earlier termination) of the lease term, we must elect one of the following options: We may (i) purchase the building from BNP for $38.5 million, (ii) if certain conditions are met, arrange for the sale of the building by BNP to a third party for an amount equal to at least $32.7 million, and be liable for any deficiency between the net proceeds received from the third party and $32.7 million, or (iii) pay BNP a supplemental payment of $32.7 million, in which event we may recoup some or all of such payment by arranging for a sale of the building by BNP during the ensuing two-year period.
	Included in the above contractual cash obligations are (a) lease commitments of $1.4 million in fiscal 2008, $2.3 million in each of the fiscal years 2009, 2010, 2011, and 2012, and $1.0 million in fiscal year 2013, which are based on the LIBOR rate at April 30, 2006 for a term of five years, and (b) at the expiration or termination of the lease, a supplemental payment obligation equal to our minimum guarantee of $32.7 million in the event that we elect not to purchase or arrange for a sale of the building.
	The lease also requires us to maintain specified financial covenants with which we were in compliance as of October 27, 2006. Such specified financial covenants include a maximum ratio of Total Debt to Earnings Before Interest, Taxes, Depreciation and Amortization (“EBITDA”) and a Minimum Unencumbered Cash and Short Term Investments.
(3)	Equipment operating leases include servers and IT equipment used in our engineering labs and data centers.
(4)	Venture capital funding commitments include a quarterly committed management fee based on a percentage of our committed funding to be payable through June 2011.
(5)	Capital expenditures include worldwide contractual commitments to purchase equipment and to construct building and leasehold improvements, which will be recorded as Property and Equipment.
(6)	We are required to pay based on a minimum volume under certain communication contracts with major telecommunication companies as well as maintenance contracts with multiple vendors. Such obligations expire in April 2010.
(7)	These amounts are included on our Consolidated Balance Sheets under Long-term Obligations and Other Accrued Liabilities, which is comprised of committed lease payments and operating expenses net of committed and estimated sublease income.
(8)	Included in these amounts are the JP Morgan Chase loan (see Note 5) on our Consolidated Balance Sheets under Current Portion of Long-Term Debt and Long-Term Debt. This amount also includes estimated interest payments of $4.2 million for the remainder of fiscal 2007 and $2.9 million for fiscal 2008. The decrease from April 30, 2006 represented a loan repayment of $78.7 million, plus interest of $6.3 million for the first six months of fiscal 2007.
(9)	The amounts outstanding under these letters of credit relate to workers’ compensation, a customs guarantee, a corporate credit card program, and a foreign rent guarantee.

43

During the quarter, two shareholder derivative lawsuits were filed against various of our officers and directors and naming us as a nominal defendant. The suits allege improper practices relating to the timing of stock option granting. Management believes that the claims are without merit and intends to defend the actions vigorously.

In addition, we are subject to various legal proceedings and claims which may arise in the normal course of business. While the outcome of these legal matters is currently not determinable, we do not believe that any current litigation or claims will have a material adverse effect on our business, cash flow, operating results, or financial condition.

Capital Expenditure Requirements

We expect capital expenditures to increase in the future consistent with the growth in our business, as we continue to invest in people, land, buildings, capital equipment, and enhancements to our worldwide infrastructure. We expect that our existing facilities and those being developed in Sunnyvale, California, Research Triangle Park (“RTP”), North Carolina, and worldwide are adequate for our requirements over at least the next two years and that additional space will be available as needed. We expect to finance all our construction projects, including our contractual commitments, operating leases, and any required capital expenditures over the next few years through cash from operations and existing cash and investments.

Off-Balance Sheet Arrangements

As of October 27, 2006, our financial guarantees of $2.3 million that were not recorded on our balance sheet consisted of standby letters of credit related to workers’ compensation, a customs guarantee, a corporate credit card program, and a foreign rent guarantee.

As of October 27, 2006, our notional fair values of foreign exchange forward and foreign currency option contracts totaled $325.8 million. We do not believe that these derivatives present significant credit risks, because the counterparties to the derivatives consist of major financial institutions, and we manage the notional amount of contracts entered into with any one counterparty. We do not enter into derivative financial instruments for speculative or trading purposes. Other than the risk associated with the financial condition of the counterparties, our maximum exposure related to foreign currency forward and option contracts is limited to the premiums paid.

We have entered into indemnification agreements with third parties in the ordinary course of business. Generally, these indemnification agreements require us to reimburse losses suffered by the third party due to various events, such as lawsuits arising from patent or copyright infringement. These indemnification obligations are considered off-balance sheet arrangements in accordance with FASB Interpretation 45, of FIN No. 45,“Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others.”

We have commitments related to a lease arrangement with BNP for approximately 190,000 square feet of office space to be located on land currently owned by us in Sunnyvale, California (as further described above under “Contractual Cash Obligations and Other Commercial Commitments”). We have evaluated our accounting for this lease under the provisions of FIN No. 46R, and have determined the following:

•  BNP is a leasing company for BNP Paribas in the U.S. BNP is not a “special purpose entity” organized for the sole purpose of facilitating the lease to us. The obligation to absorb expected losses and receive expected residual returns rests with the parent BNP Paribas. Therefore, we are not the primary beneficiary of BNP as we do not absorb the majority of BNP’s expected losses or expected residual returns; and

•  BNP has represented in the Closing Agreement (filed as Exhibit 10.40) that the fair value of the property leased to us by BNP is less than half of the total of the fair values of all assets of BNP, excluding any assets of BNP held within a silo. Further, the property leased to Network Appliance is not held within a silo. The definition of “held within a silo” means that BNP has obtained funds equal to or in excess of 95% of the fair value of the leased asset to acquire or maintain its investment in such asset through non-recourse financing or other contractual arrangements, the effect of which is to leave such asset (or proceeds thereof) as the only significant asset of BNP at risk for the repayment of such funds.

44

Accordingly, under the current FIN No. 46R standard, we are not required to consolidate either the leasing entity or the specific assets that we lease under the BNP lease. Assuming that this transaction will continue to meet the provisions of FIN No. 46R as new standards evolve over time, our future minimum lease payments under this real estates lease will amount to a total of $44.4 million reported under our Note 14 “Commitments and Contingencies.”

Liquidity and Capital Resource Requirements

Key factors affecting our cash flows include our ability to effectively manage our working capital, in particular, accounts receivable and inventories and future demand for our products and related pricing. We expect to incur higher capital expenditures in the near future to expand our operations. We will from time to time acquire products and businesses complementary to our business. In the future, we may continue to repurchase our common stock, which would reduce cash, cash equivalents,and/or short-term investments available to fund future operations and meet other liquidity requirements. Based on past performance and current expectations, we believe that our cash and cash equivalents, short-term investments, and cash generated from operations will satisfy our working capital needs, capital expenditures, stock repurchases, contractual obligations, and other liquidity requirements associated with our operations for at least the next twelve months.

Item 3.   Quantitative and Qualitative Disclosures about Market Risk

We are exposed to market risk related to fluctuations in interest rates, market prices, and foreign currency exchange rates. We use certain derivative financial instruments to manage these risks. We do not use derivative financial instruments for speculative or trading purposes. All financial instruments are used in accordance with management-approved policies.

Market Interest and Interest Income Risk

Interest and Investment Income — As of October 27, 2006, we hadavailable-for-sale investments of $1,045.8 million. Our investment portfolio primarily consists of highly liquid investments with original maturities at the date of purchase of greater than three months, which are classified asavailable-for-sale. These highly liquid investments, consisting primarily of government, municipal, corporate debt securities, and auction-rate securities, are subject to interest rate and interest income risk and will decrease in value if market interest rates increase. A hypothetical 10 percent increase in market interest rates from levels at October 27, 2006 would cause the fair value of theseavailable-for-sale investments to decline by approximately $4.2 million. Because we have the ability to hold these investments until maturity, we would not expect any significant decline in value of our investments caused by market interest rate changes. Declines in interest rates over time will, however, reduce our interest income. We do not use derivative financial instruments in our investment portfolio.

Our investment portfolio also includes common stock holdings in Blue Coat (see Note 12 of the Condensed Consolidated Financial Statements). We are exposed to fluctuations in the market price of our investment in this company. At the same time, we are precluded from selling the value of any of our holdings until September 2007. As a result of these factors, the amount of income and cash flow that we ultimately realize from this investment in future periods may vary materially from the current unrealized amount. A hypothetical 10 percent decrease in the fair market value from fair market value at October 27, 2006 would cause the fair value of this investment to decrease by approximately $0.8 million.

Lease Commitments — As of October 27, 2006, we have arrangements with BNP to lease our land for a period of 50 years to construct approximately 190,000 square feet of office space costing up to $38.5 million. After completion of construction, we will pay minimum lease payments which vary based on London Interbank Offered Rate (“LIBOR”) plus a spread. We expect to pay lease payments on the completed buildings from BNP on September 2007 for a term of five years. We have the option to renew the lease for two consecutive five-year periods upon approval by BNP. A hypothetical 10 percent increase in market interest rates from levels at October 27, 2006 would increase our total lease payments under the initial five-year term by approximately $1.0 million. We do not currently hedge against market interest rate increases. As cash from operating cash flows is invested in a higher

45

interest rate environment, it will offer a natural hedge against interest rate risk from our lease commitments in the event of a significant increase in market interest rate.

Debt Obligation — We have an outstanding variable rate term loan totaling $193.4 million as of October 27, 2006. Under terms of these arrangements, we expect to pay interest payments at LIBOR plus a spread. A hypothetical 10 percent increase in market interest rates from levels at October 27, 2006 would increase our total interest payments by approximately $1.0 million. We do not currently use derivatives to manage interest rate risk.

Equity Securities — We have from time to time made cash investments in companies with distinctive technologies that are potentially strategically important to us. Our investments in non-marketable equity securities would be negatively affected by an adverse change in equity market prices, although the impact cannot be directly quantified. Such a change, or any negative change in the financial performance or prospects of the companies whose non-marketable securities we own, would harm the ability of these companies to raise additional capital and the likelihood of our being able to realize any gains or return of our investments through liquidity events such as initial public offerings, acquisitions, and private sales. These types of investments involve a high degree of risk, and there can be no assurance that any company we invest in will grow or be successful. We do not currently engage in any hedging activities to reduce or eliminate equity price risk with respect to such equity investment. Accordingly, we could lose all or part of this investment if there is an adverse change in the market price of the company we invest in. Our investments in non-marketable equity securities had a carrying amount of $10.2 million as of October 27, 2006 and $11.0 million as of April 30, 2006. If we determine that another-than-temporary decline in fair value exists for a non-marketable equity security, we write down the investment to its fair value and record the related write-down as an investment loss in our Consolidated Statements of Income. In the second quarter of fiscal 2007, we recorded a non-cash,other-than-temporary write-down of $2.0 million related to an impairment of our investment in a privately held company.

Foreign Currency Exchange Rate Risk

We hedge risks associated with foreign currency transactions to minimize the impact of changes in foreign currency exchange rates on earnings. We utilize forward and option contracts to hedge against the short-term impact of foreign currency fluctuations on certain assets and liabilities denominated in foreign currencies. All balance sheet hedges are marked to market through earnings every period. We also use foreign exchange forward contracts to hedge foreign currency forecasted transactions related to certain sales and operating expenses. These derivatives are designated as cash flow hedges under SFAS No. 133. For cash flow hedges outstanding at October 27, 2006, the gains or losses were included in other comprehensive income.

We do not enter into foreign exchange contracts for speculative or trading purposes. In entering into forward and option foreign exchange contracts, we have assumed the risk that might arise from the possible inability of counterparties to meet the terms of their contracts. We attempt to limit our exposure to credit risk by executing foreign exchange contracts with creditworthy multinational commercial banks. All contracts have a maturity of less than one year.

Item 4.   Controls and Procedures

Disclosure controls are controls and procedures designed to ensure that information required to be disclosed in our reports filed under the Exchange Act, such as this Quarterly Report, is recorded, processed, summarized, and reported within the time periods specified in the U.S. Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures are also designed to ensure that such information is accumulated and communicated to our management, including the CEO and CFO, as appropriate to allow timely decisions regarding required disclosure.

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as defined inRules 13a-15(e) and15d-15(e) under the Securities Exchange Act of 1934, as amended, as of October 27, 2006, the end of the fiscal period covered by this quarterly report (the “Evaluation Date”). Based on this evaluation, our principal executive officer and principal financial officer concluded as of the Evaluation Date that our disclosure controls and procedures were effective such that the information relating to Network Appliance, including our consolidated subsidiaries, required to be disclosed in our Securities and Exchange Commission (“SEC”) reports (i) is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms, and (ii) is accumulated and communicated to Network Appliance’s management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

There was no change in our internal control over financial reporting that occurred during the period covered by this Quarterly Report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1.   Legal Proceedings

None

Item 1A.   Risk Factors

The following risk factors and other information included in thisForm 10-Q should be carefully considered. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties not presently known to us or that we presently deem less significant may also impair our business operations. If any of the following risks actually occur, our business, operating results, and financial condition could be materially adversely affected.

Factors beyond our control could cause our quarterly results to fluctuate, which could adversely impact our common stock price.

We believe thatperiod-to-period comparisons of our results of operations are not necessarily meaningful and should not be relied upon as indicators of future performance. Many of the factors that could cause our quarterly operating results to fluctuate significantly in the future are beyond our control and include, but are not limited to, the following:

•  Changes in general economic conditions and specific economic conditions in the computer, storage, and networking industries

•  General decrease in global corporate spending on information technology leading to a decline in demand for our products

•  A shift in federal government spending patterns

•  The possible effects of terrorist activity and international conflicts, which could lead to business interruptions and difficulty in forecasting

•  The level of competition in our target product markets

•  Our reliance on a limited number of suppliers due to industry consolidation, which could subject us to periodicsupply-and-demand, price rigidity, and quality issues with our components

•  The size, timing, and cancellation of significant orders

•  Product configuration and mix

•  The extent to which our customers renew their service and maintenance contracts with us

•  Market acceptance of new products and product enhancements

•  Announcements, introductions, and transitions of new products by us or our competitors

•  Deferrals of customer orders in anticipation of new products or product enhancements introduced by us or our competitors

•  Changes in pricing by us in response to competitive pricing actions

•  Our ability to develop, introduce, and market new products and enhancements in a timely manner

•  Supply constraints

•  Technological changes in our target product markets

•  The levels of expenditure on research and development and sales and marketing programs

•  Our ability to achieve targeted cost reductions

•  Excess or inadequate facilities

48

•  Disruptions resulting from new systems and processes as we continue to enhance and adapt our system infrastructure to accommodate future growth

•  Future accounting pronouncements and changes in accounting policies

•  Seasonality

In addition, sales for any future quarter may vary and accordingly be different from what we forecast. We manufacture products based on a combination of specific order requirements and forecasts of our customer demands. Products are typically shipped within one to four weeks following receipt of an order. In certain circumstances, customers may cancel or reschedule orders without penalty. Product sales are also difficult to forecast because the storage and data management market is rapidly evolving and our sales cycle varies substantially from customer to customer.

We derive a majority of our revenue in any given quarter from orders booked in the same quarter. Bookings typically follow intra-quarter seasonality patterns weighted towards the back end of the quarter. If we do not achieve bookings in the latter part of a quarter consistent with our quarterly financial targets, our financial results will be adversely impacted.

Due to all of the foregoing factors, it is possible that in one or more future quarters our results may fall below our forecasts and the expectations of public market analysts and investors. In such event, the trading price of our common stock would likely decrease.

If we are unable to develop and introduce new products and respond to technological change, if our new products do not achieve market acceptance, or if we fail to manage the transition between our new and old products, our operating results could be materially and adversely affected.

Our future growth depends upon the successful development and introduction of new hardware and software products. Due to the complexity of storage subsystems and storage security appliances, and the difficulty in gauging the engineering effort required to produce new products, such products are subject to significant technical risks. However, our new products may not achieve market acceptance. Additional product introductions in future periods may also impact our sales of existing products. In addition, our new products must respond to technological changes and evolving industry standards. If we are unable, for technological or other reasons, to develop and introduce new products in a timely manner in response to changing market conditions or customer requirements, or if such products do not achieve market acceptance, our operating results could be materially and adversely affected.

As new or enhanced products are introduced, we must successfully manage the transition from older products in order to minimize disruption in customers’ ordering patterns, avoid excessive levels of older product inventories, and ensure that enough supplies of new products can be delivered to meet customers’ demands.

An increase in competition could materially and adversely affect our operating results.

The storage markets are intensely competitive and are characterized by rapidly changing technology.

In the storage market, our primary and nearline storage system products, and our associated storage software portfolio compete primarily with storage system products and data management software from EMC, HDS, HP, IBM, and Sun/StorageTek. We also see Dell, Inc. as a competitor in the storage marketplace, primarily through their business partnership with EMC, allowing Dell to resell EMC storage hardware and software products. We have also historically encountered less-frequent competition from companies including Engenio Information Technologies, Inc. (formerly the Storage Systems Group of LSI Logic Corp.), Dot Hill Systems Corporation, and Xiotech Corporation. In the secondary storage market, which includes thedisk-to-disk backup, compliance, and business continuity segments, our solutions compete primarily against products from EMC and Sun/StorageTek. Our NearStore VTL appliances also compete with traditional tape backup solutions in the broader data backup/recovery space.

We also develop and market network storage security products. With the acquisition of Decru, we have gained market share in the financial services, media, telecommunications, and pharmaceutical sectors as well several government agencies worldwide. Our future potential competitors could include developers of operating systems or

49

hardware suppliers not currently offering competitive enterprise-wide security products. If any of those potential competitors begins to offer enterprise-wide security systems as a component of its product solution, demand for our storage security could decrease.

Additionally, a number of new, privately held companies are currently attempting to enter the storage systems and data management software markets, the nearline and NearStore VTL storage markets, some of which may become significant competitors in the future.

We believe that the principal competitive factors affecting the storage markets include product benefits such as response time, reliability, data availability, scalability, ease of use, price, multiprotocol capabilities, and global service and support. We must continue to maintain and enhance this technological advantage over our competitors. If those competitors with greater financial, marketing, service, support, technical, and other resources were able to offer products that matched or surpassed the technological capabilities of our products, these competitors would, by virtue of their greater resources, gain a competitive advantage over us that could lead to greater sales for these competitors at the expense of our own market share, which would have a material adverse effect on our business, financial condition, and results of operations.

Increased competition could also result in price reductions, reduced gross margins, and loss of market share, any of which could materially and adversely affect our operating results. Our competitors may be able to respond more quickly than we can to new or emerging technologies and changes in customer requirements or devote greater resources to the development, promotion, sale, and support of their products. In addition, current and potential competitors have established or may establish cooperative relationships among themselves or with third parties. Accordingly, it is possible that new competitors or alliances among competitors may emerge and rapidly acquire significant market share. We cannot assure you that we will be able to compete successfully against current or future competitors. Competitive pressures we face could materially and adversely affect our operating results.

We rely on a limited number of suppliers, and any disruption or termination of these supply arrangements could delay shipment of our products and could materially and adversely affect our operating results.

We rely on a limited number of suppliers of several key components utilized in the assembly of our products. We purchase our disk drives through several suppliers. We purchase computer boards and microprocessors from a limited number of suppliers. Our reliance on a limited number of suppliers involves several risks, including:

•  A potential inability to obtain an adequate supply of required components because we do not have long-term supply commitments

•  Supplier capacity constraints

•  Price increases

•  Timely delivery

•  Component quality

Component quality is particularly significant with respect to our suppliers of disk drives. In order to meet product performance requirements, we must obtain disk drives of extremely high quality and capacity. In addition, there are periodicsupply-and-demand issues for disk drives, microprocessors, and semiconductor memory components, which could result in component shortages, selective supply allocations, and increased prices of such components. We cannot assure you that we will be able to obtain our full requirements of such components in the future or that prices of such components will not increase. In addition, problems with respect to yield and quality of such components and timeliness of deliveries could occur. Disruption or termination of the supply of these components could delay shipments of our products and could materially and adversely affect our operating results. Such delays could also damage relationships with current and prospective customers and suppliers.

In addition, we license certain technology and software from third parties that is incorporated into our products. If we are unable to obtain or license the technology and software on a timely basis, we will not be able to deliver products to our customers in a timely manner.

50

The loss of any contract manufacturers or the failure to accurately forecast demand for our products or successfully manage our relationships with our contract manufacturers could negatively impact our ability to manufacture and sell our products.

We currently rely on several contract manufacturers to manufacture most of our products. Our reliance on our third-party contract manufacturers reduces our control over the manufacturing process, exposing us to risks, including reduced control over quality assurance, production costs, and product supply. If we should fail to effectively manage our relationships with our contract manufacturers, or if our contract manufacturers experience delays, disruptions, capacity constraints, or quality control problems in their manufacturing operations, our ability to ship products to our customers could be impaired and our competitive position and reputation could be harmed. Qualifying a new contract manufacturer and commencing volume production are expensive and time-consuming. If we are required to change contract manufacturers or assume internal manufacturing operations, we may lose revenue and damage our customer relationships. If we inaccurately forecast demand for our products, we may have excess or inadequate inventory or incur cancellation charges or penalties, which could adversely impact our operating results. As of October 27, 2006, we have no purchase commitment under these agreements.

We intend to regularly introduce new products and product enhancements, which will require us to rapidly achieve volume production by coordinating with our contract manufacturers and suppliers. We may need to increase our material purchases, contract manufacturing capacity, and internal test and quality functions to meet anticipated demand. The inability of our contract manufacturers to provide us with adequate supplies of high-quality products, or the inability to obtain raw materials, could cause a delay in our ability to fulfill orders.

Our future financial performance depends on growth in the storage and data management markets. If these markets do not continue to grow at the rates at which we forecast growth, our operating results will be materially and adversely impacted.

All of our products address the storage and data management markets. Accordingly, our future financial performance will depend in large part on continued growth in the storage and data management markets and on our ability to adapt to emerging standards in these markets. We cannot assure you that the markets for storage and data management will continue to grow or that emerging standards in these markets will not adversely affect the growth of UNIX^®, Windows^®, and the World Wide Web server markets upon which we depend.

For example, we provide our open access data retention solutions to customers within the financial services, healthcare, pharmaceuticals, and government market segments, industries that are subject to various evolving governmental regulations with respect to data access, reliability, and permanence (such as Rule 17(a)(4) of the Securities Exchange Act of 1934, as amended) in the United States and in the other countries in which we operate. If our products do not meet, and continue to comply with, these evolving governmental regulations in this regard, customers in these market and geographical segments will not purchase our products, and therefore we will not be able to expand our product offerings in these market and geographical segments at the rates for which we have forecast.

In addition, our business also depends on general economic and business conditions. A reduction in demand for storage and data management caused by weakening economic conditions and decreases in corporate spending will result in decreased revenues and lower revenue growth rates. The network storage market growth declined significantly beginning in the third quarter of fiscal 2001 through fiscal 2003, causing both our revenues and operating results to decline. If the storage and data management markets grow more slowly than anticipated, or if emerging standards other than those adopted by us become increasingly accepted by these markets, our operating results could be materially and adversely affected.

Our gross margins may vary based on the configuration of our product and service solutions, and such variation may make it more difficult to forecast our earnings.

We derive a significant portion of our sales from the resale of disk drives as components of our storage systems, and the resale market for hard disk drives is highly competitive and subject to intense pricing pressures. Our sales of disk drives generate lower gross margin percentages than those of our storage systems. As a result, as we sell more

51

highly configured systems with greater disk drive content, overall gross margin percentages may be negatively affected.

Our gross margins have been and may continue to be affected by a variety of other factors, including:

•  Demand for storage and data management products

•  Discount levels and price competition

•  Direct versus indirect and OEM sales

•  Product and add-on software mix

•  The mix of services as a percentage of revenue

•  The mix and average selling prices of products

•  The mix of disk content

•  New product introductions and enhancements

•  Excess inventory purchase commitments as a result of changes in demand forecasts and possible product and software defects as we transition our products

•  The cost of components, manufacturing labor, and quality

Changes in service gross margins may result from various factors such as continued investments in our customer support infrastructure and changes in the mix between technical support services and professional services, as well as the timing of technical support service contract initiations and renewals.

Our effective tax rate may increase or fluctuate, which could increase our income tax expense and reduce our net income.

Our effective tax rate could be adversely affected by several factors, many of which are outside of our control, including:

•  Earnings being lower than anticipated in countries where we are taxed at lower rates as compared to the United States statutory tax rate

•  Material differences between forecasted and actual tax rates as a result of a shift in the mix of pre-tax profits and losses by tax jurisdiction, our ability to use tax credits, or effective tax rates by tax jurisdiction different than our estimates

•  Changing tax laws, accounting standards, including SFAS No. 123R, regulations, and interpretations in multiple tax jurisdictions in which we operate, as well as the requirements of certain tax rulings

•  An increase in expenses not deductible for tax purposes, including certain stock compensation, write-offs of acquired in-process research and development, and impairment of goodwill

•  The tax effects of purchase accounting for acquisitions and restructuring charges that may cause fluctuations between reporting periods

•  Changes in the valuation of our deferred tax assets and liabilities

•  Changes in tax laws or the interpretation of such tax laws

•  Tax assessments, or any related tax interest or penalties, could significantly affect our income tax expense for the period in which the settlements take place

•  A change in our decision to indefinitely reinvest foreign earnings

The price of our common stock could decline to the extent that our financial results are materially affected by an adverse change in our effective tax rate. We are currently undergoing federal income tax audits in the U.S. and several foreign tax jurisdictions. The rights to some of our intellectual property (“IP”) are owned by certain of our

52

foreign subsidiaries, and payments are made between U.S. and foreign tax jurisdictions relating to the use of this IP. Recently, some other companies have had their foreign IP arrangements challenged as part of an examination. Our management does not believe, based upon information currently known to us, that the final resolution of any of our audits will have a material adverse effect upon our consolidated financial position and the results of operations and cash flows. If the ultimate determination of our taxes owed in any of these tax jurisdictions is for an amount in excess of the tax provision we have recorded or reserved for, our operating results, cash flows, and financial condition could be adversely affected.

We may incur problems with current or future acquisitions and equity investments, and these investments may not achieve our objectives.

As part of our strategy, we are continuously evaluating opportunities to buy other businesses or technologies that would complement our current products, expand the breadth of our markets, or enhance our technical capabilities. We may engage in future acquisitions that dilute our stockholders’ investments and cause us to use cash, to incur debt, or to assume contingent liabilities.

Acquisitions of companies entail numerous risks, and we may not be able to successfully integrate acquired operations and products or to realize anticipated synergies, economies of scale, or other value. Integration risks and issues may include, but are not limited to, key personnel retention and assimilation, management distraction, technical development, and unexpected costs and liabilities, including goodwill impairment charges. In addition, we may be unable to recover strategic investments in development stage entities. Any such problems could have a material adverse effect on our business, financial condition, and results of operation.

From time to time, we also make equity investments for the promotion of business and strategic objectives. We have already made strategic investments in a number of storage and data management-related technology companies. Equity investments may result in the loss of investment capital. The market price and valuation of our equity investments in these companies may fluctuate due to market conditions and other circumstances over which we have little or no control. To the extent that the fair value of these securities is less than our cost over an extended period of time, our results of operations and financial position could be negatively impacted. In the second quarter of fiscal 2007, we recorded a $2.0 million write-down relating to our investment in a technology company.

We cannot assure you that our OEM relationship with IBM will generate significant revenue.

In April 2005, we announced a strategic partner relationship with IBM. As part of the relationship, we entered into an original equipment manufacturing (OEM) agreement that enables IBM to sell IBM branded solutions based on Network Appliance unified and open network attached storage (NAS) and iSCSI/IP SAN solutions, including NearStore and the NetApp V-Series systems, as well as associated software offerings. While this agreement is an element of our strategy to expand our reach into more customers and countries, we do not have an exclusive relationship with IBM and there is no minimum commitment for any given period of time; therefore we cannot assure you that this relationship will contribute any revenue in future years. In addition, we have no control over the products that IBM selects to sell, or their release schedule and timing of those products; nor do we control their pricing. Revenues from the IBM relationship were not significant during the first six-months of fiscal 2007 and fiscal year 2006. Revenues from IBM accounted for 3.1% and 2.9% of our total consolidated revenue for the three- and six-month periods ended October 27, 2006. Revenues from IBM accounted for 1.0% of our total consolidated revenue for the fiscal year 2006. In the event that sales through IBM will increase, we may experience distribution channel conflicts between our direct sales force and IBM, or among our channel partners. If we fail to minimize channel conflicts, our operating results and financial condition could be harmed. In addition, since this agreement is relatively new, we do not have a history upon which to base our analysis of its future success.

Currently we do not and cannot assure you that this OEM relationship will generate significant revenue or that this strategic partnership will continue to be in effect for any specific period of time.

53

If we are unable to maintain our existing relationships and develop new relationships with major strategic partners, our revenue may be impacted negatively.

An element of our strategy to increase revenue is to strategically partner with major third-party software and hardware vendors that integrate our products into their products and also comarket our products with these vendors. We have significant partner relationships with database, business application, and backup management companies, including Microsoft^®, Oracle^®, SAP, and Symantec^tm. A number of these strategic partners are industry leaders that offer us expanded access to segments of the storage market. There is intense competition for attractive strategic partners, and even if we can establish strategic relationships with these partners, we cannot assure you that these partnerships will generate significant revenue or that the partnerships will continue to be in effect for any specific period of time.

We intend to continue to establish and maintain business relationships with technology companies to accelerate the development and marketing of our storage solutions. To the extent that we are unsuccessful in developing new relationships and maintaining our existing relationships, our future revenue and operating results could be impacted negatively. In addition, the loss of a strategic partner could have a material adverse effect on the progress of our new products under development with that partner.

We cannot assure you that we are able to maintain existing resellers and attract new resellers, and that channel conflicts will not materially adversely affect our channel relationships. In addition, we do not have exclusive relationships with our resellers and accordingly there is a risk that those resellers may give higher priority to products of other suppliers, which could materially adversely affect our operating results.

We market and sell our storage solutions directly through our worldwide sales force and indirectly through channels such as value-added resellers, or VARs, systems integrators, distributors, OEMs, and strategic business partners, and we derive a significant portion of our revenue from these indirect channel partners. In the three-month period ended October 27, 2006, Fujitsu Siemens and our two-tier distribution partners, Arrow and Avnet, accounted for 3.3% and 12.1%, respectively, of our consolidated revenue. In the three-month period ending October 28, 2005, Fujitsu Siemens and our two-tier distribution partners, Arrow and Avnet, accounted for 3.2% and 11.5%, respectively, of our consolidated revenue.

However, in order for us to maintain our current revenue sources and grow our revenue as we have forecasted, we must effectively manage our relationships with these indirect channel partners. To do so, we must attract and retain a sufficient number of qualified channel partners to successfully market our products. However, because we also sell our products directly to customers through our sales force, on occasion we compete with our indirect channels for sales of our products to our end customers, competition that could result in conflicts with these indirect channel partners and make it harder for us to attract and retain these indirect channel partners. At the same time, our indirect channel partners may offer products that are competitive to ours. In addition, because our reseller partners generally offer products from several different companies, including products of our competitors, these resellers may give higher priority to the marketing, sales, and support of our competitors’ products than ours. If we fail to effectively manage our relationships with these indirect channel partners to minimize channel conflict and continue to evaluate and meet our indirect sales partners’ needs with respect to our products, we will not be able to maintain or increase our revenue as we have forecasted, which would have a materially adverse affect on our business, financial condition, and results of operations. Additionally, if we do not manage distribution of our products and services and support effectively, or if our resellers’ financial conditions or operations weaken, our revenues and gross margins could be adversely affected.

Risks inherent in our international operations could have a material adverse effect on our operating results.

We conduct business internationally.  For the three- and six-month periods ended October 27, 2006, 40.5% and 41.8%, respectively, of our total revenues were from international customers (including U.S. exports). Accordingly, our future operating results could be materially and adversely affected by a variety of factors, some of which are beyond our control, including regulatory, political, or economic conditions in a specific country or

54

region, trade protection measures and other regulatory requirements, government spending patterns, and acts of terrorism and international conflicts.

Our international sales are denominated in U.S. dollars and in foreign currencies. An increase in the value of the U.S. dollar relative to foreign currencies could make our products more expensive and therefore potentially less competitive in foreign markets. Conversely, lowering our price in local currency may result in lowerU.S.-based revenue. For international sales and expenditures denominated in foreign currencies, we are subject to risks associated with currency fluctuations. We utilize forward and option contracts to hedge our foreign currency exposure associated with certain assets and liabilities as well as anticipated foreign currency cash flows. All balance sheet hedges are marked to market through earnings every quarter, while gains and losses on cash flow hedges are recorded in other comprehensive income until forecasted transactions occur, at which time such realized gains and losses are recognized in earnings. These hedges attempt to reduce, but do not always entirely eliminate, the impact of currency exchange movements. Factors that could have an impact on the effectiveness of our hedging program include the accuracy of forecasts and the volatility of foreign currency markets. There can be no assurance that such hedging strategies will be successful and that currency exchange rate fluctuations will not have a material adverse effect on our operating results.

Additional risks inherent in our international business activities generally include, among others, longer accounts receivable payment cycles and difficulties in managing international operations. Such factors could materially and adversely affect our future international sales and consequently our operating results.

We receive significant tax benefits from sales to ournon-U.S. customers. These benefits are contingent upon existing tax regulations in the U.S. and in the countries in which our international operations are located. Future changes in domestic or international tax regulations could adversely affect our ability to continue to realize these tax benefits. Our effective tax rate could also be adversely affected by different and evolving interpretations of existing law or regulations. Potentially adverse tax consequences could negatively impact the operating and financial results from international operations. International operations currently benefit from a tax ruling concluded in the Netherlands.

Although operating results have not been materially and adversely affected by seasonality in the past, because of the significant seasonal effects experienced within the industry, particularly in Europe, our future operating results could be materially and adversely affected by seasonality.

We cannot assure you that we will be able to maintain or increase international market demand for our products.

If we fail to manage our expanding business effectively, our operating results could be materially and adversely affected.

Our future operating results depend to a large extent on management’s ability to successfully manage expansion and growth, including but not limited to expanding international operations, forecasting revenues, addressing new markets, controlling expenses, implementing and enhancing infrastructure, systems and processes, and managing our assets.

The growth in our business requires that we invest in people, processes and systems to best optimize our revenue growth and long- term profitability. However, growth in our sales or continued expansion in the scope of our operations could strain our current management, financial, manufacturing, and other systems, and may require us to implement and improve those systems. If we experience any problems with any improvement or expansion of these systems, procedures, or controls, or if these systems, procedures or controls are not designed, implemented, or improved in a cost-effective and timely manner, our operations may be materially and adversely affected. In addition, any failure to implement, improve, and expand such systems, procedures, and controls in a timely and efficient manner could harm our growth strategy and materially and adversely affect our financial condition and ability to achieve our business objectives.

In addition, an unexpected decline in the growth rate of revenues without a corresponding and timely reduction in expense growth or a failure to manage other aspects of growth could materially and adversely affect our operating results.

55

A significant percentage of our expenses are fixed, which could materially and adversely affect our net income.

Our expense levels are based in part on our expectations as to future sales, and a significant percentage of our expenses are fixed. As a result, if sales levels are below expectations or previously higher levels, net income will be disproportionately affected in a material and adverse manner.

The marketplace for our common stock has fluctuated significantly in the past and will likely continue to do so in the future.

The market price for our common stock has experienced substantial volatility in the past, and several factors could cause the price to fluctuate substantially in the future. These factors include but are not limited to:

•  Fluctuations in our operating results

•  Fluctuations in the valuation of companies perceived by investors to be comparable to us

•  Economic developments in the storage and data management market as a whole

•  International conflicts and acts of terrorism

•  A shortfall in revenues or earnings compared to securities analysts’ expectations

•  Changes in analysts’ recommendations or projections

•  Announcements of new products, applications, or product enhancements by us or our competitors

•  Changes in our relationships with our suppliers, customers, and channel and strategic partners

•  General market conditions

In addition, the stock market has experienced volatility that has particularly affected the market prices of equity securities of many technology companies. Additionally, certain macroeconomic factors such as changes in interest rates, the market climate for the technology sector, and levels of corporate spending on information technology could also have an impact on the trading price of our stock. As a result, the market price of our common stock may fluctuate significantly in the future, and any broad market decline, as well as our own operating results, may materially and adversely affect the market price of our common stock.

We depend on the ability of our personnel, raw materials, equipment, and products to move reasonably unimpeded around the world. Our business could be materially and adversely affected as a result of a natural disaster, terrorist acts, or other catastrophic events.

Any political, military, world health (e.g., SARS, avian flu), or other issue which hinders this movement or restricts the import or export of materials could lead to significant business disruptions. Furthermore, any strike, economic failure, or other material disruption cased by fire, floods, hurricanes, power loss, power shortages, telecommunications failures, break-ins, and similar events could also adversely affect our ability to conduct business. If such disruptions result in cancellations of customer orders or contribute to a general decrease in economic activity or corporate spending on information technology, or directly impact our marketing, manufacturing, financial, and logistics functions, our results of operations and financial condition could be materially adversely affected. In addition, our headquarters are located in Northern California, an area susceptible to earthquakes. If any significant disaster were to occur, our ability to operate our business could be impaired.

We depend on attracting and retaining qualified technical and sales personnel. If we are unable to attract and retain such personnel, our operating results could be materially and adversely impacted.

Our continued success depends, in part, on our ability to identify, attract, motivate, and retain qualified technical and sales personnel. Because our future success is dependent on our ability to continue to enhance and introduce new products, we are particularly dependent on our ability to identify, attract, motivate, and retain qualified engineers with the requisite education, background, and industry experience. Competition for qualified engineers, particularly in Silicon Valley, can be intense. The loss of the services of a significant number of our

56

engineers or salespeople could be disruptive to our development efforts or business relationships and could materially and adversely affect our operating results.

Undetected software errors, hardware errors, or failures found in new products may result in loss of or delay in market acceptance of our products, which could increase our costs and reduce our revenues.

Our products may contain undetected software errors, hardware errors, or failures when first introduced or as new versions are released. Despite testing by us and by current and potential customers, errors may not be found in new products until after commencement of commercial shipments, resulting in loss of or delay in market acceptance, which could materially and adversely affect our operating results.

If we are unable to protect our intellectual property, we may be subject to increased competition that could materially and adversely affect our operating results.

Our success depends significantly upon our proprietary technology. We rely on a combination of copyright and trademark laws, trade secrets, confidentiality procedures, contractual provisions, and patents to protect our proprietary rights. We seek to protect our software, documentation, and other written materials under trade secret, copyright, and patent laws, which afford only limited protection. Some U.S. trademarks and someU.S.-registered trademarks are registered internationally as well. We will continue to evaluate the registration of additional trademarks as appropriate. We generally enter into confidentiality agreements with our employees and with our resellers, strategic partners, and customers. We currently have multiple U.S. and international patent applications pending and multiple U.S. patents issued. The pending applications may not be approved, and if patents are issued, such patents may be challenged. If such challenges are brought, the patents may be invalidated. We cannot assure you that we will develop proprietary products or technologies that are patentable, that any issued patent will provide us with any competitive advantages or will not be challenged by third parties, or that the patents of others will not materially and adversely affect our ability to do business.

Litigation may be necessary to protect our proprietary technology. Any such litigation may be time consuming and costly. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy aspects of our products or to obtain and use information that we regard as proprietary. In addition, the laws of some foreign countries do not protect proprietary rights to as great an extent as do the laws of the United States. We cannot assure you that our means of protecting our proprietary rights will be adequate or that our competitors will not independently develop similar technology, duplicate our products, or design around patents issued to us or other intellectual property rights of ours.

We are subject to intellectual property infringement claims. We may, from time to time, receive claims that we are infringing third parties’ intellectual property rights. Third parties may in the future claim infringement by us with respect to current or future products, patents, trademarks, or other proprietary rights. We expect that companies in the appliance market will increasingly be subject to infringement claims as the number of products and competitors in our industry segment grows and the functionality of products in different industry segments overlaps. Any such claims could be time consuming, result in costly litigation, cause product shipment delays, require us to redesign our products, or require us to enter into royalty or licensing agreements, any of which could materially and adversely affect our operating results. Such royalty or licensing agreements, if required, may not be available on terms acceptable to us or at all.

Adverse resolution of litigation may harm our operating results or financial condition.

We are a party to lawsuits in the normal course of our business. Litigation can be expensive, lengthy, and disruptive to normal business operations. Moreover, the results of complex legal proceedings are difficult to predict. An unfavorable resolution of a particular lawsuit could have a material adverse effect on our business, operating results, or financial condition.

57

Our business is subject to increasingly complex corporate governance, public disclosure, accounting, and tax requirements that have increased both our costs and the risk of noncompliance.

Because our common stock is publicly traded, we are subject to certain rules and regulations of federal, state, and financial market exchange entities charged with the protection of investors and the oversight of companies whose securities are publicly traded. These entities, including the Public Company Accounting Oversight Board, the SEC, and NASDAQ, have implemented new requirements and regulations and continue developing additional regulations and requirements in response to recent corporate scandals and laws enacted by Congress, most notably the Sarbanes-Oxley Act of 2002. Our efforts to comply with these new regulations have resulted in, and are likely to continue resulting in, increased general and administrative expenses and diversion of management time and attention from revenue-generating activities to compliance activities.

We have recently completed our evaluation of our internal controls over financial reporting as required by Section 404 of the Sarbanes-Oxley Act of 2002. Although our assessment, testing, and evaluation resulted in our conclusion that as of April 30, 2006, our internal controls over financial reporting were effective, we cannot predict the outcome of our testing in future periods. If our internal controls are ineffective in future periods, our business and reputation could be harmed. We may incur additional expenses and commitment of management’s time in connection with further evaluations, either of which could materially increase our operating expenses and accordingly reduce our net income.

Because new and modified laws, regulations, and standards are subject to varying interpretations in many cases due to their lack of specificity, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This evolution may result in continuing uncertainty regarding compliance matters and additional costs necessitated by ongoing revisions to our disclosure and governance practices.

Our results of operations could vary as a result of the methods, estimates, and judgments that we use in applying our accounting policies.

The methods, estimates, and judgments that we use in applying our accounting policies have a significant impact on our results of operations (see “Critical Accounting Estimates and Policies” in Part I, Item 2 of thisForm 10-Q). Such methods, estimates and judgments are, by their nature, subject to substantial risks, uncertainties and assumptions, and factors may arise over time that lead us to change our methods, estimates and judgments. Changes in those methods, estimates and judgments could significantly affect our results of operations. In particular, the calculation of stock-based compensation expense under SFAS No. 123R requires us to use valuation methodologies (which were not developed for use in valuing employee stock options) and make a number of assumptions, estimates, and conclusions regarding matters such as expected forfeitures, expected volatility of our share price, and the exercise behavior of our employees. Changes in these variables could impact our stock-based compensation expense and have a significant impact on our gross margins, R&D and S&M, G&A expenses, and stock price. If another party asserts that the fair value of our employee stock options is misstated, securities class action litigation could be brought against us, or the market price of our common stock could decline, or both could occur. As a result, we could incur significant losses, and our operating results may be below our expectations and those of investors and stock market analysts.

Our ability to forecast earnings is limited by the impact of new accounting requirements such as SFAS No. 123R.

The Financial Accounting Standards Board requires companies to recognize the fair value of stock options and other share-based payment compensation to employees as compensation expense in the statement of income. Option pricing models require the input of highly subjective assumptions, including the expected stock price volatility, expected life, and forfeiture rate. We have chosen to base our estimate of future volatility using the implied volatility of traded options to purchase the Company’s common stock as permitted by SAB No. 107. As of May 1, 2006, the contractual life of our stock options has been shortened to seven years from ten years for options issued on or after this date, and to the extent that the shorter life changes employees’ exercise behavior, it may change the expected term of an option going forward. SFAS No. 123R requires us to use estimated forfeitures, and therefore the adoption of SFAS No. 123R could have a material impact on the timing of and, based on the accuracy

58

of estimates of future actual forfeitures, the amount of stock compensation expense. Given the unpredictable nature of the “Black Scholes” variables and other management assumptions such as number of options to be granted, underlying strike price, and associated income tax impacts, it is very difficult to estimate stock compensation expense for any given quarter or year. Any changes in these highly subjective assumptions may significantly impact our ability to make accurate forecasts of future earnings.

We are subject to various environmental laws and regulations that could impose substantial costs upon us and may adversely affect our business.

We may from time to time be subject to various state, federal, and international laws and regulations governing the environment, including those restricting the presence of certain substances in electronic products and making producers of those products financially responsible for the collection, treatment, recycling, and disposal of certain products. For example, the European Union (“EU”) has enacted the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (“RoHS”) and the Waste Electrical and Electronic Equipment (“WEEE”) directives. RoHS prohibits the use of certain substances, including mercury and lead, in certain products put on the market after July 1, 2006. The WEEE directive obligates parties that place electrical and electronic equipment onto the market in the EU to put a clearly identifiable mark on the equipment, register with and report to EU member countries regarding distribution of the equipment, and provide a mechanism to take back and properly dispose of the equipment. Each EU member country has enacted, or is expected to soon enact, legislation clarifying what is and what is not covered by the WEEE directive in that country. We have met the requirements of the RoHS and WEEE directives, including adhering to the July 1, 2006 deadline for meeting RoHS material composition restrictions. Similar laws and regulations have been or may be enacted in other regions.

We face increasing complexity in our product design, logistics, and procurement operations as we adjust to new and upcoming requirements relating to the materials composition of our products. Other environmental regulations may require us to reengineer products to utilize components which are more environmentally compatible, and such reengineering and component substitution may result in additional costs to us. Notwithstanding our ability or willingness to reengineer products or to pay additional costs, we still may be adversely affected if the materials and components that we need are unavailable to us. In addition, if we were found to be in violation of these laws, we could be subject to governmental fines, any noncompliant products may be banned from European markets, and our customers may incur liability. Although we do not anticipate any material adverse effects based on the nature of our operations and the effect of such laws, there is no assurance that such existing laws or future laws will not have an adverse effect on us.

The U.S. government has contributed to our revenue growth and become an important customer for us. However, government demand is unpredictable, and there is no guarantee of future revenue growth from the U.S. government.

The U.S. government has become an important customer for the storage market and for us. Government agencies are subject to budgetary processes and expenditure constraints that could lead to delays or decreased capital expenditures in IT spending on infrastructures. If the government or individual agencies within the government reduce or shift their capital spending pattern, our financial results may be harmed. We cannot assure you that revenue from the U.S. government will continue to grow in the future.
