Condensed Consolidated Financial Statements [Abstract]
Condensed Consolidated Financial Statements	CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
	Basis of Presentation. The accompanying unaudited condensed consolidated financial statements reflect all adjustments, consisting only of normal, recurring adjustments that, in the opinion of management, are necessary for a fair presentation of the results of operations for the periods presented. These unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) applicable to interim financial information. The results for the interim periods are not necessarily indicative of results for the entire year or any future periods. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements for the fiscal year ended June 27, 2014, which are included in the Company's Annual Report on Form 10-K filed with the SEC on September 8, 2014.
	The preparation of unaudited condensed consolidated financial statements in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, and expenses as presented in the accompanying unaudited condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates.
	Fiscal Year. The Company has a 52 or 53-week fiscal year ending on the last Friday in June. The current fiscal year 2015 will be comprised of 52 weeks and will end on June 26, 2015. Fiscal year 2014 was comprised of 52 weeks and ended on June 27, 2014.
	In fiscal year 2015, the Company's fiscal quarters end on September 26, 2014 (first quarter), December 26, 2014 (second quarter), March 27, 2015 (third quarter) and June 26, 2015 (fourth quarter).
	In fiscal year 2014, the Company's fiscal quarters ended on September 27, 2013 (first quarter), December 27, 2013 (second quarter), March 28, 2014 (third quarter) and June 27, 2014 (fourth quarter).
	Principles of Consolidation. The unaudited condensed consolidated financial statements include the accounts of the Company and all of its subsidiaries. All intercompany accounts and transactions have been eliminated.
	Revenue and Cost of Revenue for Product and Service. For arrangements which include software licenses and undelivered post contract customer support ("PCS"), where we have not established vendor-specific objective evidence ("VSOE") of fair value of the undelivered element, revenue and related cost of revenue from these arrangements have been deferred and recognized ratably over the PCS period and historically been classified as combined product and service revenue and cost of revenue in the consolidated statements of operations. Revenue and cost of revenue for these types of arrangements are no longer material, as such, amounts are reported as revenue and cost of revenue for product or service. Amounts previously reported as combined product and service revenue and cost of revenue for the three and nine months ended March 28, 2014 have been reclassified to conform to the three and nine months ended March 27, 2015.

Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	There have been no changes in the Company's significant accounting policies for the three months ended March 27, 2015 as compared to those disclosed in the Company's Annual Report on Form 10-K for the year ended June 27, 2014.
	Recently Issued Accounting Standards.
	Simplifying the Presentation of Debt Issuance Costs. In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2015-03, “Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs,” which provides a more simplified presentation of debt issuance costs than under existing U.S. GAAP. ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from that debt liability, consistent with the presentation of a debt discount. The amendments in ASU 2015-03 are effective for financial statements issued for fiscal year beginning after December 15, 2015, and interim periods within those fiscal years with early application permitted. This guidance will be effective during the Company's third quarter of fiscal 2016. The adoption of this standard will not have a significant effect on the Company's condensed consolidated statements of operations.
	Revenue from Contracts with Customers. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” which supersedes the revenue recognition requirements in Topic 605, “Revenue Recognition” and requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The amendments in ASU 2014-09 are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period, with early application not permitted. This guidance will be effective for the Company in fiscal 2018. On April 1, 2015, the FASB issued a proposed amendment to the ASU which, if approved, would allow companies to choose to delay the adoption of this standard for one year. The Company is currently evaluating the effects, if any, which the adoption of this guidance will have on the Company’s financial position, results of operations and cash flows.
	Reporting of Discontinued Operations and Disclosures of Disposals of Component of an Entity. In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2014-08, “Reporting of Discontinued Operations and Disclosures of Disposals of Components of an Entity,” which provides a narrower definition of discontinued operations than under existing U.S. GAAP. ASU 2014-08 requires that only a disposal of a component of an entity, or a group of components of an entity, that represents a strategic shift that has, or will have, a major effect on the reporting entity’s operations and financial results should be reported in the financial statements as discontinued operations. ASU 2014-08 also provides guidance on the financial statement presentations and disclosures of discontinued operations. The amendments in ASU 2014-08 are effective for all disposals of components of an entity that occur within annual periods beginning on or after December 15, 2014, and interim periods within annual periods beginning on or after December 15, 2015, with early application permitted. This guidance will be effective during the Company's third quarter of fiscal 2016. The adoption of this standard will not have a significant effect on the Company's condensed consolidated statements of operations.

Acquisitions
	ACQUISITION
	On September 30, 2013 (the "Closing Date"), the Company acquired certain assets of FileTek, Inc. ("FileTek"), a global provider of High Performance Data Analytics storage virtualization, large-scale data management, and active archive solutions. The total purchase price was approximately $9.2 million in cash. This acquisition expanded the Company's storage solutions by enabling customers to manage data assets efficiently and lower the cost and administration of high-volume storage. Under the terms of the agreement, SGI acquired FileTek's StorHouse and Trusted Edge software, worldwide customers, engineering team, and services and support resources.
	The acquired assets and assumed liabilities were recorded by the Company at their estimated fair values as part of the Products segment. The Company determined the estimated fair values using estimates and valuations including discounted cash flow and cost approach analyses.
	The following table summarizes the allocation of the purchase price to the estimated fair values of the assets acquired and liabilities assumed as of the Closing Date (in thousands):
			Amount
	Tangible assets acquired		$	169
	Tangible liabilities assumed		(2,922		)
	Net tangible liabilities		(2,753		)
	Intangible assets		4,900
	Goodwill		7,053
	Total net asset acquired		$	9,200
	The fair value of the major components of the intangibles assets acquired and their estimated useful lives is as follows (in thousands):
						Weighted Average Useful Life
	Intangible Asset Class		Fair Value			(in Years)
	Purchased technology		$	4,400		6.25
	Maintenance and service agreements and related relationships		400			4
	Trade name / trademarks		100			4
	Total intangible assets		$	4,900
	Acquisition and integration costs directly related to the acquisition were $0.2 million and were recorded in selling, general and administrative expenses. Such costs are expensed in accordance with the authoritative guidance.
	Unaudited Pro Forma Financial Information
	The unaudited financial information in the table below summarizes the combined results of operations for the Company and FileTek on a pro forma basis, as though the companies had been combined as of the beginning of fiscal 2014. The pro forma financial information is presented for informational purposes only and may not be indicative of the results of operations that would have been achieved if the acquisition had taken place at the beginning of fiscal year 2014. The pro forma financial information for nine months ended March 28, 2014 include the business combination accounting effect on historical FileTek revenue, amortization and development charges from acquired intangible assets and related tax effects.

	As a result of a decision made in the fourth quarter of fiscal 2014 to stop further investment in development of these next generation storage products, the Company determined that the intangible assets related to the product development of these next generation products were impaired. The Company recorded an impairment charge of $2.9 million in the fourth quarter of fiscal 2014, impacting cost of revenue. During the second quarter of fiscal 2015, the Company decided to cease selling and supporting these products and determined that the remaining intangible assets related to this acquisition were impaired. The Company recorded an impairment charge of $1.1 million during the nine months ended March 27, 2015, impacting cost of revenue by $0.8 million and sales expense by $0.3 million.

Contract Manufacturing	CONTRACT MANUFACTURING
	In July 2013, the Company selected Jabil Circuit, Inc. ("Jabil") as its primary global manufacturing services and supply chain management provider. The transition to Jabil was expected to be implemented as a “manage in place” model, which would utilize existing SGI facilities and personnel. On November 18, 2013, the Company signed an asset purchase agreement with Jabil, whereby Jabil would purchase SGI’s primary manufacturing facility, located in Chippewa Falls, Wisconsin and certain other manufacturing assets for $6.3 million in cash.
	The total carrying of these assets held for sale were written down to their fair value of $6.3 million, resulting in an impairment charge of $0.9 million recorded in general and administrative expenses during the nine months ended March 28, 2014.
	SGI expected that approximately 120 of its manufacturing personnel in Chippewa Falls would transfer to Jabil. During the second quarter of fiscal 2014, the Company accrued approximately $0.7 million of compensation costs associated with the transfer of these employees as part of the agreement with Jabil, which was recorded within cost of revenue.
	During the fourth quarter of fiscal 2014, the Company reevaluated its outsourcing model given lower than anticipated volumes of Company product sales.  On August 4, 2014, the Company terminated the planned manage-in-place outsourcing structure and the asset purchase agreement referenced above. SGI paid approximately $0.6 million to Jabil for certain assets that were purchased for the manage-in-place model as well as for costs associated with streamlining the manufacturing process. In addition, SGI reversed the $0.7 million accrual previously booked for compensation costs associated with the proposed employee transfer discussed above. The Company will continue to optimize all of its manufacturing capabilities with the objective of improving efficiency and flexibility.

Fair Value Disclosures [Abstract]
Financial Instruments and Fair Value	FINANCIAL INSTRUMENTS AND FAIR VALUE
	The Company measures its assets and liabilities at fair value based upon the expected exit price, representing the amount that would be received on the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value reflects the assumptions market participants would use in pricing an asset or liability based on the best information available. Assumptions include the risks inherent in a particular valuation technique (such as a pricing model) and/or the risks inherent in the inputs to the model.
	The Company uses a three-level fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:
	•	Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;
	•	Level 2 - Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly; and
	•	Level 3 - Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.
	The Company's assessment of the hierarchy level of the assets or liabilities measured at fair value is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Company considers an active market to be one in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis, and views an inactive market as one in which there are a few transactions for the asset or liability, the prices are not current, or price quotations vary substantially either over time or among market makers. Where appropriate, the Company or the counterparty's non-performance risk is considered in determining the fair values of liabilities and assets, respectively.

	There were no transfers between Level 1 and Level 2 of the fair value hierarchy during both the three and nine months ended March 27, 2015 and March 28, 2014. The Company’s cash equivalents, consisting of money market funds, are classified within Level 1 of the fair value hierarchy as they were valued using quoted market prices of the identical underlying securities in active markets.
	Level 2 assets include investments that are pooled with other investments held by insurance companies within their general funds for our pension plans.  The investments held by the insurance companies are valued by taking the percentage owned by the plan in the underlying net asset value of the insurance company's general fund. The valuation of the underlying net assets of the insurance company's general fund is based on quoted market prices of the investments in active markets or for quoted market prices in active markets of similar assets. The market inputs used to value these instruments generally consist of market yields, reported trades, broker/dealer quotes or alternative pricing sources with reasonable levels of price transparency. Pricing sources include industry standard data providers, security master files from large financial institutions and other third party sources. Our derivative financial instruments are classified within Level 2, as there is not an active market for each hedge contract, but the inputs used to calculate the value of the instruments are tied to active markets.
	The fair values of accounts receivable, accounts payable, and accrued liabilities, due within one year approximates their carrying values because of their short-term nature.
	Assets and Liabilities Measured at Fair Value on a Non-recurring Basis
	The Company does not have any assets or liabilities measured at fair value on a non-recurring basis as of March 27, 2015 and June 27, 2014.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	DERIVATIVES
	The Company is exposed to foreign currency exchange rate fluctuations in the normal course of its business. As part of the Company's risk management strategy, the Company uses derivative instruments, primarily forward contracts to hedge economic exposures resulting from changes in foreign currency exchange rates.
	Cash Flow Hedges
	Beginning in fiscal 2014, the Company implemented a cash flow hedging strategy to protect anticipated non-functional currency revenues and expenses. The Company uses forward contracts designated as cash flow hedges to hedge a portion of future forecasted non-U.S. Dollar ("USD") cash flows. In general, these foreign exchange contracts, carried at fair value, have maturities between one and twelve months. As of March 27, 2015, the Company had 10 open hedges in an aggregate notional amount in USD equivalent to approximately $49.6 million. The Company currently designates hedges for the Euro, British Pound, Czech Koruna, and the Australian Dollar. These derivative instruments are designated and qualify as cash flow hedges under the criteria prescribed in the authoritative guidance. All amounts related to gains / losses on designated hedges, currently in accumulated other comprehensive income ("AOCI") are expected to be reclassified into earnings over the next 12 months.
	For derivative instruments that are designated and qualify as cash flow hedges under Accounting Standards Codification ("ASC") No. 815-Derivatives and Hedging, the effective portion of the gain or loss on the derivative is reported as a component of accumulated other comprehensive loss and reclassified into earnings into the same financial statement line as the item being hedged. SGI assesses the prospective and retrospective effectiveness of its hedge programs using statistical analysis. The Company uses the spot-to-spot method to measure ineffectiveness in the hedge relationship. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in other income (expense), net. For derivative instruments that are not designated as hedging instruments under ASC No. 815 or that have been de-designated following recognition of the hedge item, gains and losses are recognized in other income (expense), net.
	Balance Sheet Hedges
	Additionally, the Company enters into foreign exchange contracts to hedge monetary assets and liabilities that are denominated in currencies other than the functional currency of its subsidiaries. These foreign exchange contracts are carried at fair value and do not qualify for hedge accounting treatment and are not designated as hedging instruments. Changes in fair value of these derivatives are recognized in other income (expense), net in the condensed consolidated statement of operations, in the current period, along with the offsetting foreign currency gain or loss on the underlying assets or liabilities. As of March 27, 2015, the Company had 19 open non-designated hedges in an aggregate USD-equivalent notional amount totaling approximately $8.9 million.
	The before tax effect of derivative instruments for foreign exchange contracts designated as hedging instruments and non-designated hedging instruments in our condensed consolidated statement of operations during the three and nine months ended March 27, 2015 and March 28, 2014 was as follows (in thousands):

	Total		$	881			$	239		$	2,072			$	1,079
	The Company's use of derivative instruments exposes it to non-performance risk to the extent that the counterparties may be unable to meet the terms of the agreement. The Company does, however, seek to mitigate such risks by limiting its counterparties to major financial institutions which are selected based on their credit ratings and other factors. The Company has established policies and procedures for mitigating non-performance risk that include establishing counterparty credit limits, monitoring credit exposures, and continually assessing the creditworthiness of counterparties. Therefore the Company does not consider counterparty non-performance risk a material risk at this time.
	A number of the Company's derivative agreements contain threshold limits to the net liability position with counterparties and are dependent on the Company's corporate credit rating determined by the major credit rating agencies. The counterparties to the derivative instruments may request collateralization, in accordance with derivative agreements, on derivative instruments in net liability positions.
	The aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a net asset position as of March 27, 2015, was $2.8 million. The credit-risk-related contingent features underlying these agreements had not been triggered as of March 27, 2015.
	As of March 27, 2015, the Company has designated derivatives with notional values of approximately $49.6 million and non-designated derivatives with notional values of approximately $8.9 million in Euro, British Pound, Czech Koruna, the Australian Dollar and Japanese Yen.
	Derivative instruments are subject to master netting arrangements and are disclosed gross in the statement of financial position. The gross fair values and location of derivative instruments included in the condensed consolidated statement of financial position as of March 27, 2015 and June 27, 2014, were as follows (in thousands):

	The Company reviews the carrying values of long-lived assets for indicators of impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of long-lived assets is measured by a comparison of the carrying amount of the assets to the estimated undiscounted future cash flows expected to be generated by the assets.
	As a result of a decision made in the second quarter of fiscal 2015 to cease selling and supporting certain storage products, the Company determined that intangible assets related to these products were impaired. The Company recorded an impairment charge of $1.1 million during the nine months ended March 27, 2015, impacting cost of revenue by $0.8 million and sales expense by $0.3 million. Also see Note 4, Acquisitions.
	Intangible assets amortization and impairment expense was $0.1 million and $1.0 million in the three months ended March 27, 2015 and March 28, 2014, respectively.

Term Loan	TERM LOAN
	On January 27, 2015, the Company entered into a new credit agreement (the "Term Loan") among the Company, certain lenders and Morgan Stanley Senior Funding, Inc., as administrative and collateral agent and lead arranger. The Term Loan provided an aggregate principal amount of $70.0 million with a term of three and a half years, bearing interest at the LIBO Rate (as defined in the Credit Agreement), subject to a 1.0% minimum, plus 9.0% per annum. The Term Loan provided $66.4 million of cash, net of borrowing and origination costs of approximately $3.6 million which was used to pay off the prior credit facility and provide cash and cash equivalents sufficient to fund working capital requirements, capital expenditures and operations. As of March 27, 2015, the Company had a $70.0 million outstanding principal balance owed on the Term Loan of which approximately $1.8 million was classified as short-term debt in current liabilities. The Company was in compliance with all covenants under the Term Loan, as of March 27, 2015.
	Pursuant to the Term Loan, certain wholly-owned domestic subsidiaries of the Company (the “Guarantors”) have guaranteed the obligations of the Company under the Term Loan. The Term Loan and related loan documents replaced the Company’s prior Credit Agreement dated December 5, 2011, by and among the Company, certain lenders party thereto, and Wells Fargo Capital Finance, LLC, as administrative agent (as amended from time to time, the “Prior Credit Facility”). All commitments under the Prior Credit Facility were terminated and all borrowings thereunder were repaid, effective January 27, 2015. The remaining obligations of Company and guarantor party to the Prior Credit Facility and related loan documents are limited to certain remaining contingent indemnification obligations under such facility. See Note 18, Credit Facility, for more information about the Prior Credit Facility.
	The Term Loan and related loan documents contain covenants that limit the ability of the Company and certain of its subsidiaries, among other things, to:
	•	issue any preferred stock;
	•	incur or guarantee indebtedness;
	•	create, incur, assume, or permit liens to exist;
	•	consummate asset sales, acquisitions or mergers;
	•	dispose of property
	•	pay dividends or repurchase stock;
	•	make investments;
	•	enter into transactions with affiliates; or
	•	enter into or permit certain type of agreements to exist.
	The Term Loan also requires compliance with a minimum adjusted current ratio and a $10.0 million minimum unrestricted cash balance, calculated as set forth in the Term Loan.
	The Term Loan contains customary events of default, including:
	•	failure to make required payments;
	•	material breaches of representations and warranties;
	•	failure to comply with certain agreements or covenants;
	•	failure to pay, or default under, certain other indebtedness;
	•	certain events of bankruptcy and insolvency;
	•	failure to pay certain judgments; and
	•	a change of control.
	We may not prepay the loan during the first year and may only prepay the loan during the second year at a premium. After such time, we may prepay the loan without penalty.

The total fair value of shares vested during the nine months ended March 27, 2015 and March 28, 2014 was $1.1 million and $2.0 million, respectively.
	As of March 27, 2015, there was $0.1 million of total unrecognized compensation cost related to non-vested stock options, which is expected to be recognized over a weighted average period of 0.50 years.
	Restricted Stock Unit Activity
	The following table summarizes the Company's activity with respect to restricted stock units (“RSUs”) for the nine months ended March 27, 2015:
		Number of
		Shares
	Balance at June 27, 2014	1,696,823
	Awarded	1,264,760
	Released	(642,357	)

	Balance at March 27, 2015	2,016,543
	Vested and expected to vest at March 27, 2015	1,577,791
	In August 2014, the Company granted time-based RSUs ("2014 executive time-based RSUs") and performance-based RSUs (“2014 executive PSUs”) to members of the Company's executive management team.  The 2014 executive time-based RSUs vest quarterly over four years, subject to the recipient's continuous service through each vesting date. The 2014 executive PSUs initially vest as to one-fourth of their amount on the third business day following Compensation Committee review of the Company’s goal attainment for the fiscal year ending June 26, 2015, so long as (a) the Company’s total stockholder return meets the median total stockholder return of its peer group (50% weighting), and (b) the Company’s financial results meet targets established by the Board for certain product sales and bookings for fiscal 2015 (two goals with 25% weighting each). The 2014 executive PSUs may be increased or decreased depending on the level of attainment by the Company of the performance metrics established by the Board. Achievement of the aforementioned performance criteria will result in a vesting percentage determined in accordance with a vesting matrix. At attainment of 75% or below, vesting will be at 50%. At 100% attainment, vesting will be at 125%. At 125% attainment or above, vesting will be at 150%. If the conditions for initial vesting of the 2014 executive PSUs are met, the remaining portion of the 2014 executive PSUs will vest in twelve equal, successive quarterly installments over an additional three years, subject to continued service through each vesting date.
	The Company estimated the fair value of its 2014 executive PSUs using a Monte Carlo simulation model with the assumptions discussed above. For purposes of reporting and determining the share-based compensation expense as of March 27, 2015, the company estimated that 257,500 of the 2014 executive PSUs will be awarded.  The Company assesses the achievement of these performance metrics on a quarterly basis.
	As of March 27, 2015, there was $8.9 million of total unrecognized compensation cost related to RSUs, which is expected to be recognized over a weighted average period of 1.40 years.
	RSUs are converted into common stock upon vesting. Upon the vesting of restricted stock, the Company generally uses the net share settlement approach, which withholds a portion of the shares to cover the applicable taxes and decreases the shares issued to the employee by a corresponding value. The withholding tax obligations are based upon the fair market value of the Company's common stock on the vesting date. The number and the value of the shares netted for employee taxes are summarized in the table below (in thousands except share amounts):
		Three Months Ended								Nine Months Ended
		27-Mar-15				28-Mar-14				27-Mar-15			28-Mar-14
	RSUs shares withheld for taxes	93,546				61,886				219,747			164,302
	RSUs amounts withheld for taxes	$	890			$	654			$	2,086		$	2,096
	Employee Stock Purchase Plan
	At March 27, 2015, the total unrecognized compensation cost related to options to purchase the Company's common stock under the employee stock purchase plan ("ESPP") was approximately $1.5 million. This cost will be amortized on a straight-line basis over approximately 1.9 years. The following table shows the shares issued and their respective weighted-average purchase price per share, pursuant to the ESPP, during the three and nine months ended March 27, 2015 and March 28, 2014.

Stock Repurchase Program	STOCK REPURCHASE PROGRAM
	In January 2013, the Company's board of directors approved a plan for the Company to repurchase shares of its common stock with a market value of up to $15.0 million. In November 2013, the Company announced an increase in the authorized repurchased amount to $30.0 million and in November 2014, the Company announced that it had extended its repurchase program through December 31, 2015. The Company's common stock may be repurchased in the open market or through negotiated transactions, including 10b5-1 trading plans that would enable the Company to repurchase its shares during periods outside of its normal trading windows. Purchases will cease if the authorized funds are spent or the program is discontinued. The Company is not obligated to acquire any particular amount of stock, and the program may be suspended or terminated at any time at the Company's discretion.
	These repurchases are reflected in our balance sheet as treasury stock and are available for future issuance. The following table shows the total number of shares repurchased during the period (in thousands, except per share amount):
		Treasury Stock
		Number of Shares	Amount		Average Purchase Price Per Share
	Balance at June 27, 2014	1,844	$	18,677	$	10.13

	Three months ended March 27, 2015	—	—		N/A
	Balance at March 27, 2015	2,315	$	22,899	$	9.89
	Since the inception of the repurchase plan in January 2013, the Company has repurchased approximately 1,566,000 shares of its common stock for approximately $18.0 million. As of March 27, 2015, the Company had a remaining authorization of approximately $12.0 million for future share repurchases; however the new credit agreement signed in January 2015 restricts the ability of the Company to repurchase stock while borrowings under the agreement remain outstanding. SGI does not anticipate repurchasing stock while such debt is outstanding. See Note 17, Term Loan, for more information about the new credit agreement.

Earnings Per Share [Abstract]
Earnings Per Share	PER SHARE
	Basic net income (loss) per common share is computed by dividing unaudited consolidated net income (loss) by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is computed by dividing unaudited consolidated net income (loss) by the weighted average number of common shares outstanding and dilutive common shares outstanding during the period. For both of the three and nine months ended March 27, 2015 and March 28, 2014, the effect of outstanding options and RSUs were anti-dilutive to loss per share and were therefore excluded from the calculation of diluted loss per share.
	The dilutive effect of outstanding options and RSUs is reflected in diluted net income per share, but not diluted loss per share, by application of the treasury stock method, which includes consideration of share-based compensation required by accounting principles generally accepted in the U.S. Since the Company generated a net loss in both the three and nine months ended March 27, 2015 and March 28, 2014, basic and diluted net loss per share are the same for these periods.
	The following table sets forth the computation of basic and diluted net loss per share for the three and nine months ended March 27, 2015 and March 28, 2014 (in thousands, except per share amount):

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES
	The Company recorded tax provision of approximately $0.1 million and $0.6 million for the three and nine months ended March 27, 2015, respectively. The tax expense primarily was comprised of tax liability computed based on the Company’s projected foreign financial results for the year ending June 26, 2015, state taxes, interest for unrecognized tax benefits and U.S. deferred tax liability related to nondeductible goodwill, partially offset by tax benefits from expiring statute of limitations and tax refunds in foreign jurisdictions. The effective tax rate differed from the combined federal and net state statutory income tax rate for the three and nine months ended March 27, 2015, primarily due to the tax rate differential of the Company's foreign operations and utilization of net operating losses not previously recognized.
	The Company recorded tax provision of approximately $0.5 million and $0.9 million for the three and nine months ended March 28, 2014, respectively. The tax provision primarily was comprised of tax liability computed based on the Company’s projected full-year foreign taxes, state taxes, tax reserves and related interest, offset by tax benefits from the reversal of previously accrued interest and tax refunds in foreign jurisdictions. The effective tax rate differed from the combined federal and net state statutory income tax rate for the three and nine months ended March 28, 2014, primarily due to the tax rate differential of the Company's foreign operations and utilization of net operating losses not previously recognized
	As of March 27, 2015, the Company has provided a partial valuation allowance against its net deferred tax assets. Management continues to evaluate the realizability of deferred tax assets and related valuation allowance. If management's assessment of the deferred tax assets or the corresponding valuation allowance were to change, the Company would record the related adjustment to income during the period in which management makes the determination.
	The Company had approximately $6.4 million of gross unrecognized tax benefit as of March 27, 2015, of which $1.8 million will impact the effective tax rate when recognized. The Company recognizes interest expense and penalties related to the unrecognized tax benefits within income tax expense. As of March 27, 2015, the Company also had approximately $7.4 million of interest and penalties attributable to the gross unrecognized tax benefits. It is reasonably possible that over the next twelve-month period the Company may experience an increase or decrease in its unrecognized tax benefits.

Segment Reporting [Abstract]
Segment Information	SEGMENT INFORMATION
	Commencing in the first quarter of fiscal 2015, the Company started managing its business primarily as two separate business units, Products and Service. The Company has combined both the Compute and Storage solutions into a single Product Business Unit. The Company's operating segments are determined based upon several criteria including: the Company's internal organizational structure; the manner in which the Company's operations are managed; the criteria used by the Company's Chief Executive Officer, the Chief Operating Decision Maker (“CODM”), to evaluate segment performance; and the Company's availability of separate financial information.
	A description of the Company's two reportable segments is as follows:
	Product—The Product segment is comprised of our Compute and Storage solutions. Compute solutions include our scale-out computing, scale-up computing, software and cloud/web solutions. Compute solutions also include integrated third-party hardware and software products that we sell to provide a single source solution for our customers. Our compute solutions are designed to minimize the number and complexity of interconnects for power and data transfer to improve reliability, speed of implementation and serviceability. Storage solutions include both hardware and software offerings to address virtually every type of data storage and management requirement. Products range from entry-level disk arrays to complex storage systems, with innovative technology and hardware. Our storage solutions are designed to provide extreme scale, broad flexibility and to minimize the cost to store data.
	Service—The Service segment is comprised of customer service support and professional services. Our customer support organization provides ongoing maintenance and technical support for our products and some third-party products, as well as contracted maintenance services, hardware deployment services (install and de-install), time and materials-based services and spare parts. Our professional services organization provides value added services associated with technology consulting, project management and customer education, all of which help our customers realize the full value of their information technology investments.
	All historical segment numbers for the three and nine months ended March 28, 2014 have been recast to conform to the three and nine months ended March 27, 2015.
	The Company's CODM evaluates the performance of its operating segments based on revenue and operating profit (loss). Revenues are generally allocated based on the type of products and service provided to our customers. Operating profit (loss) for each segment includes related cost of sales and operating expenses directly attributable to the segment. A portion of the segments' expenses arise from shared services and infrastructure that the Company provides to the segments in order to realize economies of scale and to efficiently use resources. These expenses, collectively called corporate charges, include costs of centralized research and development and other corporate infrastructure expenses. The corporate charges that are directly attributable to the segments are allocated and are reassessed on a periodic basis. The allocations have been determined on a basis that the Company considers to be a reasonable reflection of the utilization of services provided to or benefits received by the segments. The profitability of each of the segments is measured after excluding share-based compensation expenses, amortization and impairment of intangibles, restructuring charges, manufacturing transition costs, general and administration charges, other unallocated corporate charges and other items as noted in the reconciliation below as management does not include this information in its measurement of the performance of the operating segments.

	The segment information is presented on the basis which the Company's CODM evaluates the performance of its operating segments.
	The Company's assets are located primarily in the United States and are not allocated to any specific region. The Company does not measure the performance of its business segments on any asset-based metrics. Therefore, reportable segment information is presented only for revenue and operating profit (loss).
	Customer information
	A significant portion of the Company's revenue was generated from a limited number of customers. For the three months ended March 27, 2015, various agencies of the United States government, excluding system integrators (collectively, U.S. government), accounted for approximately 15% of the Company's revenue.
	For the three months ended March 28, 2014, two customers represented 10 percent or more of the Company's total net revenue. Various agencies of the U.S. government and another customer accounted for approximately 14% and 13% of the Company's revenue, respectively.
	For the nine months ended March 27, 2015 and March 28, 2014, various agencies of the U.S. government accounted for approximately 19% and 20% of the Company's revenue, respectively.
	At March 27, 2015, one customer accounted for approximately 11% of the Company's accounts receivable. At June 27, 2014, two customers accounted for approximately 27% of the Company's accounts receivable.

	Letter of Credit
	As of March 27, 2015, the Company has a $2.0 million outstanding letter of credit with Wells Fargo bank to back the Company's obligation to pay or perform when required to do so pursuant to the requirements of an underlying agreement or the provision of goods or services to a supplier.
	Indemnification Agreements
	The Company enters into standard indemnification agreements with its customers and certain other business partners in the ordinary course of business. These agreements include provisions for indemnifying the customer against any claim brought by a third party to the extent any such claim alleges that the Company's product infringes a patent, copyright or trademark, or misappropriates a trade secret, of that third-party. The agreements generally limit the scope of the available remedies in a variety of industry-standard methods, including, but not limited to, product usage and geography-based limitations, a right to control the defense or settlement of any claim and a right to replace or modify the infringing products to make them non-infringing. The Company has not incurred significant expenses related to these indemnification agreements and no material claims for such indemnifications were outstanding as of March 27, 2015. As a result, the Company believes the estimated fair value of these indemnification agreements, if any, to be immaterial; accordingly, no liability has been recorded with respect to such indemnifications as of March 27, 2015.
	Contingencies
	The Company may, from time to time, be involved in legal proceedings and disputes that arise in the normal course of business. These matters include product liability actions, patent infringement actions, contract disputes, domestic and international federal, state and local tax reviews and audits and other matters. The Company also may be subject to litigation and/or adverse rulings or judgments as a result of certain contractual indemnification obligations. The Company records a provision for a liability when management believes that it is both probable that a liability has been incurred and it can reasonably estimate the amount of the loss. The Company believes it has adequate provisions for any such matters. The Company reviews these provisions at least quarterly and adjusts these provisions to reflect the impact of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular case.
	Third parties in the past have asserted, and may in the future assert, intellectual property infringement claims against the Company, and such future claims, if proven, could require the Company to pay substantial damages or to redesign its existing products or pay fees to obtain cross-license agreements. Litigation may be necessary in the future to enforce or defend the Company's intellectual property rights, to protect the Company's trade secrets or to determine the validity and scope of its proprietary rights or the proprietary rights of others. Any such litigation could result in substantial costs and diversion of management resources, either of which could harm the Company's business, operating results and financial condition. Further, many of the Company's current and potential competitors have the ability to dedicate substantially greater resources to enforcing and defending their intellectual property rights than the Company.
	Additionally, from time to time, the Company receives inquiries from regulatory agencies informally requesting information or documentation. There can be no assurance in any given case that such informal review will not lead to further proceedings involving the Company in the future.
	The Company is not aware of any pending disputes, including those outlined above, that would be likely to have a material adverse effect, either individually or in the aggregate, on its consolidated financial condition, results of operations or liquidity. However, litigation is subject to inherent uncertainties and costs and unfavorable outcomes could occur. An unfavorable outcome could include the payment of monetary damages, cash or other settlement, or an injunction prohibiting it from selling one or more products. If an unfavorable resolution were to occur, there exists the possibility of a material adverse impact on the Company's consolidated financial condition, results of operations or cash flows of the period in which the resolution occurs or on future periods.
	Other Commitments
	For a description of significant leases and purchase commitments see Note 24 of the Company's Annual Report on Form 10-K filed with the SEC on September 8, 2014.

	In fiscal year 2015, the Company's fiscal quarters end on September 26, 2014 (first quarter), December 26, 2014 (second quarter), March 27, 2015 (third quarter) and June 26, 2015 (fourth quarter).
	In fiscal year 2014, the Company's fiscal quarters ended on September 27, 2013 (first quarter), December 27, 2013 (second quarter), March 28, 2014 (third quarter) and June 27, 2014 (fourth quarter).
Consolidation	Principles of Consolidation. The unaudited condensed consolidated financial statements include the accounts of the Company and all of its subsidiaries. All intercompany accounts and transactions have been eliminated.
Recently Issued Accounting Standards	Recently Issued Accounting Standards.
	Simplifying the Presentation of Debt Issuance Costs. In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2015-03, “Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs,” which provides a more simplified presentation of debt issuance costs than under existing U.S. GAAP. ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from that debt liability, consistent with the presentation of a debt discount. The amendments in ASU 2015-03 are effective for financial statements issued for fiscal year beginning after December 15, 2015, and interim periods within those fiscal years with early application permitted. This guidance will be effective during the Company's third quarter of fiscal 2016. The adoption of this standard will not have a significant effect on the Company's condensed consolidated statements of operations.
	Revenue from Contracts with Customers. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” which supersedes the revenue recognition requirements in Topic 605, “Revenue Recognition” and requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The amendments in ASU 2014-09 are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period, with early application not permitted. This guidance will be effective for the Company in fiscal 2018. On April 1, 2015, the FASB issued a proposed amendment to the ASU which, if approved, would allow companies to choose to delay the adoption of this standard for one year. The Company is currently evaluating the effects, if any, which the adoption of this guidance will have on the Company’s financial position, results of operations and cash flows.
	Reporting of Discontinued Operations and Disclosures of Disposals of Component of an Entity. In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2014-08, “Reporting of Discontinued Operations and Disclosures of Disposals of Components of an Entity,” which provides a narrower definition of discontinued operations than under existing U.S. GAAP. ASU 2014-08 requires that only a disposal of a component of an entity, or a group of components of an entity, that represents a strategic shift that has, or will have, a major effect on the reporting entity’s operations and financial results should be reported in the financial statements as discontinued operations. ASU 2014-08 also provides guidance on the financial statement presentations and disclosures of discontinued operations. The amendments in ASU 2014-08 are effective for all disposals of components of an entity that occur within annual periods beginning on or after December 15, 2014, and interim periods within annual periods beginning on or after December 15, 2015, with early application permitted. This guidance will be effective during the Company's third quarter of fiscal 2016. The adoption of this standard will not have a significant effect on the Company's condensed consolidated statements of operations.
Product and Service Revenue	Product and Service. For arrangements which include software licenses and undelivered post contract customer support ("PCS"), where we have not established vendor-specific objective evidence ("VSOE") of fair value of the undelivered element, revenue and related cost of revenue from these arrangements have been deferred and recognized ratably over the PCS period and historically been classified as combined product and service revenue and cost of revenue in the consolidated statements of operations. Revenue and cost of revenue for these types of arrangements are no longer material, as such, amounts are reported as revenue and cost of revenue for product or service. Amounts previously reported as combined product and service revenue and cost of revenue for the three and nine months ended March 28, 2014 have been reclassified to conform to the three and nine months ended March 27, 2015.
