Brocade reported Q1 revenues of $546M and non-GAAP diluted earnings per share (EPS) of $0.12, which exceeded our prior

guidance range of $0.09 to $0.10 for the quarter. Our revenues in the quarter represented a 1.2% increase year-over-year

(Yr./Yr.) and a slight decrease sequentially as expected, following an all-time record revenue quarter in Q4 FY10.

A highlight in Q1 was our ability to maintain momentum in our Ethernet products revenue, which was up 32% Yr./Yr. fueled by

growth in EMEA and Asia Pacific (APAC) in terms of geographies. In addition, we saw strong traction in the Service Provider and

Enterprise businesses in terms of customer segments.

Another highlight was the performance of our storage area networking (SAN) products revenue, which was up approximately 5%

sequentially. Specifically, we are seeing healthy end-user demand for our SAN products as customers continue to invest

in their

data center networking infrastructures to address IT imperatives

such as server virtualization sprawl and private cloud

initiatives. These dynamics are also having a positive impact in

our Director and Server products businesses. As servers run

more virtual machines, the connection rate to storage increases and the demand for SAN switching increases. In Q1, Brocade

generated its second-highest Director product revenue, its highest Server product revenue and record sell-through or end-user

demand for its SAN business.

Award-Winning Brocade VDX 6720/ Brocade VCS Technology:

Brocade VCS technology to enable a new category of data center networks, or Ethernet fabrics, that are purpose-built to

help our customers simplify their network architectures and manage the rampant growth of server virtualization inside of their

data centers. This is a critical technology building block towards highly automated, private cloud architectures that many

customers are evaluating today.

The initial reception of the Brocade VDX 6720 from customers, industry pundits and other luminaries has been very positive.

Customers who are evaluating an Ethernet fabric solution have told us, “If you are building a cloud environment, you must

start with the assumption that it will need an Ethernet fabric as its foundation”. We are also proud of the fact that CTOEdge

named the Brocade VDX 6720 the “Most Important Enterprise Product for 2010,” pointing out that “this offering heralds a

change in the way we think about managing data centers for years to come.” We also received favorable feedback about

Ethernet fabrics from the CIO of the United States government, Vivek Kundra, as part of a larger discussion on data center

consolidation strategies and cloud computing best practices. These two topics are top-of-mind for Mr. Kundra, as evidenced

by their prominence in his “25 Point Implementation Plan to Reform Federal Information Technology Management”.

In terms of key metrics, Q1 saw Brocade winning some significant deals for the Brocade VDX 6720 at large enterprise

customers in a number of targeted vertical markets; energy, high-tech, media and communications. These customers have

already deployed their Brocade VDX 6720 switches into production environments in high-performance, low-latency top-of-

rack switch configurations with plans to migrate to Ethernet fabric clusters later. These early customers helped the Brocade

VDX 6720 surpass our goals for Q1 in both unit shipments and revenue. In future quarters, we expect to leverage our time-

to-market advantage in this category.

We designed the Brocade VDX 6720 Switch and

The IP/Ethernet networking world is also dealing with massive scale in

terms of global digital data and private network/Internet traffic growth. The proliferation of connected mobile devices, the

rapid adoption of public cloud computing services, the migration toward next-generation 4G cellular as well as IPv6

technologies are some of the factors driving customers to either upgrade or refresh their service provider and data center

networks today.

The Brocade MLXe Core Router, which was named the “Product of the Year” by Internet Telephony magazine, is designed

to tackle these challenges, offering industry-leading 1/10/100 Gigabit Ethernet (GbE) wire-speed density, high reliability,

and cost-saving operational efficiency for the world’s most demanding networks.

As customers and the industry make the transition to IPv6 technology, which has garnered significant media attention

recently, the high-performance and reliability of the Brocade MLXe

will be vital. Industry experts say that IP addresses

available through IPv4 are nearly exhausted. This is hastening the migration to IPv6 among service providers and

enterprises alike. The Brocade MLXe

is one of a comprehensive set of IPv6-certified products that Brocade offers to

simplify this migration for customers, without compromising performance levels. It is yet another example of how we’re

applying the Brocade One strategy to solve the most critical problems our customers face.

2. Grow the Ethernet Business

2011 Brocade Communications Systems, Inc.

Page 12 of 41

In Q1, our Ethernet products revenue grew more than 32% Yr./Yr. and total Ethernet revenue (products

and services) was up almost 23% Yr./Yr. Other positive signs include Q1 being the best quarter in winning

new Ethernet customer accounts since we started to track and report on this metric. EMEA was a particular

area of strength for us with the highest growth ever in terms of

new Ethernet accounts and nearly 50%

sequential growth in terms of Ethernet products revenue. APAC had double-digit sequential growth in Q1,

and was up over 65% Yr./Yr.

Consistent with our prior guidance for the quarter, the Federal Ethernet business in Q1 was down

sequentially, but was up more than 22% on a Yr./Yr. basis. Our non-Federal Ethernet business in the

Americas was up 37% on a Yr./Yr. basis.

Channel Partner Momentum

Page 13 of 41

Overall, I am pleased with our execution in our Ethernet business, which is a key success factor in Brocade being able to

grow our top-line profitably. We will continue to enhance existing business initiatives and introduce new ones to drive growth

in this market. Focusing on channel partner success is one example of this, because it is a critical go-to-market route for the

Ethernet business.

In Q1, Brocade successfully recruited an additional 11 Elite and Premier channel partners to our Alliance Partner Network

(APN), giving us a total of 315 such partners globally, adding to the almost 7000 Select partners in the program. We also

introduced a number of new and enhanced APN program features that are designed specifically to educate, train and certify

our partners to better address data center, virtualization and cloud computing business opportunities.

Brocade’s channel programs received significant industry recognition in this quarter when CRN Magazine, a high-profile

publication aimed at resellers, named Vice President of Worldwide Channels Barbara Spicek and Chief Marketing Officer

John McHugh among its “Top 100 Most Influential Executives”.

3. Maintain SAN Leadership

Maintaining Brocade’s leadership in the SAN market is just as important as growing our Ethernet Business. Brocade continues

to demonstrate leadership and generate momentum in the storage networking industry in both the traditional Fibre Channel

market as well as the emerging converged networking market.

Our strength in the SAN products business is reflected in the Q1 results with approximately 5% growth sequentially and an all-

time record in terms of sell-through following a very good Q4 FY10.

It is also reflected in the momentum of our Director and Server products businesses, which both experienced very strong

demand in Q1 including a record quarter for the Server products.

Additionally, we are showing good progress in sales of our Ethernet fabric products supporting multiple and converged

protocols. These products include the Brocade 8000 FCoE Switch, the Brocade 1010/1020 Converged Network Adapters

(CNAs), Brocade VDX 6720 and embedded FCoE blades. The sales of these 10 GbE-based convergence products in Q1 was up

approximately 110% sequentially and more than 320% Yr./Yr., showing that customers are turning to Brocade to connect their

servers, both physical and virtual, to shared storage, regardless of technology or protocol. We are committed to providing

leadership in this emerging category.

Getting back to Fibre

Channel, this technology continues to be, by a wide margin, the

preferred protocol to provide shared

storage for server virtualization and desktop virtualization. In

fact, the rapidly growing adoption for both server and desktop

virtualization is a driving force toward continually faster connections in Fibre

Channel technology. Brocade again expects to

lead this technology transition with our plans to introduce a full suite of next generation 16 Gbps

products and solutions from

server adapters, embedded and fabric switches to directors/backbones later this year.

Another proof point of the relative health of the Fibre

Channel business is the fact that our OEM partners are continuing to

invest in Fibre

Channel technology. In addition, most industry research firms who track the Fibre

Channel market are predicting

growth in 2011 and well beyond, which supports our belief that this market is healthy and growing.

4. Generate More Awareness

2011 Brocade Communications Systems, Inc.

Page 16 of 41

One focus area in our FY 11 Playbook is our goal to generate broader global awareness of Brocade as a complete networking

solutions provider and not just the leading “SAN company”. In fact, one of the goals of our Brocade One strategy is to

demonstrate that Brocade is leading the transformation of the network in all areas of IT with the goal of helping our

customers transition smoothly to a world where information and applications can reside anywhere.

We have focused our global marketing and corporate communications efforts on high-impact programs to accomplish this.

Driving industry thought-leadership with contributions from across the company is an example. In the technology arena, this

is exemplified by our recent efforts to promote Ethernet fabrics

as the de facto

category name for next-generation, flat Layer

2 networks for virtualized data centers. In the non-technology realm, Brocade being awarded the prestigious “Pinnacle Grand

Prize”

by the Association for Financial Professionals for our innovative process to converge strategic liquidity planning with

enterprise risk management is another recent example of our thought-leadership.

Finally, our company-wide use of social media to communicate directly to all our key audiences including customers,

partners, investors and employees is an example of how Brocade is specifically leveraging the power of networking to

generate awareness. Please take a look at our social media campaigns and assets for yourselves at

brocade.com/socialmedia.

5. Be an Employer of Choice

2011 Brocade Communications Systems, Inc.

Page 17 of 41

Another important focus area in the FY 11 Playbook is our goal to be an “employer of choice”. We received an important industry

validation when Fortune Magazine, for the second year in a row, named Brocade as one of the “100 Best Companies to Work

For”.

The Fortune 100 list is based on direct feedback from our employees who gave us high marks in the areas of innovation,

fostering a professional team environment, community giving, compensation, and flexible work environment. In the spirit of using

social media more, I encourage you to view my short video about the Fortune 100 award at

Brocade executed well in Q1, achieving revenues of $546M which was up 1.2% Yr./Yr. and down slightly Qtr./Qtr., in line with

the guidance we shared with you on our last earnings call. Storage demand was very strong in Q1 with SAN sell-through

reaching an all-time high for the company. Storage product revenues were up 4.9%

Qtr./Qtr., in a quarter when OEM partners

reduced their inventory positions as expected. OEM inventories are now at their lowest since Q4 09. Ethernet product

revenues were up 32.2% Yr./Yr. driven by growth across all geographies. Ethernet product revenues were down 11.5%

Qtr./Qtr. from our all-time record revenue in Q4 driven by lower Federal spending, consistent with our prior guidance.

Non-GAAP earnings per share on a diluted basis was $0.12 for Q1, which includes a benefit from a lower-than-expected US

Federal tax rate resulting from the passage of the R&D tax credit bill. Excluding this benefit our non-GAAP EPS for Q1 would

have been $0.11, which is higher than the guidance we provided of $0.09 to $0.10 for the quarter. We generated $118M in

operating cash flow in Q1, the highest cash generation since Q4 09, which we used to pay down our term loan and to build our

cash balance.

Managing the business to our 2-year target model

2011 Brocade Communications Systems, Inc.

Page 21 of 41

Turning first to revenues, Q1 revenues were $546.0M in a quarter where we saw good execution across our business

segments and particularly in our EMEA and APAC geographies. Revenues came in near the high end of the guidance

range we provided in our Q4 earnings call driven by strong storage demand and where both EMEA and APAC posted

record percentage contribution of revenue for the company in Q1.

Storage product revenues were up 4.9% sequentially driven by higher director and server sales which were up 16% and

6%, respectively, compared to Q4. Ethernet product revenues were down 11.5% sequentially driven by lower Federal

revenue as expected, partially offset by growth in the international regions led by EMEA. We continue to see progress in

our Ethernet sales investments and are pleased with the improvements and growth in both EMEA and APAC this quarter.

Global Services revenues were down 3.6% sequentially driven by associated lower Ethernet support revenue. OEM

inventory levels exiting the quarter were down to about two weeks of supply, as expected, as OEMs trimmed their

inventory entering the seasonally slower quarters of the year.

Non-GAAP Gross Margins of 62.0% were at the high end of our guidance range of 61.5% to 62.0% for the quarter driven

by the strong storage performance. Non-GAAP gross margins in the quarter were comfortably within our 2-year target

model range of 61% to 63%.

Non-GAAP operating margins were 17.1%, above the guidance we gave of 15% to 16% for the quarter, and in our 2-year

target model range of 17% to 20%. The sequential decline in operating margins was driven by slightly lower gross

margins and higher operating expenses as a percentage of revenue driven by our sales and marketing investments over

the past two quarters. Q1 non-GAAP operating expenses were higher as a percentage of revenue at 44.9%, but lower

than the guidance of 46% to 47% for the quarter.

The Q1 11 effective non-GAAP tax rate was 15.9% and effective GAAP tax benefit was (26.6%). Both tax rates reflect

the benefit from the US R&D tax credit that was approved during Q1 by the US Congress.

Looking to the Balance Sheet, we repaid $39.7M of our senior secured debt of which $30.0M was in excess of the

mandatory amount due, bringing our acquisition term debt down to approximately $311M. Total Q1 diluted shares were

491M shares and within our expected range when we provided our outlook for the quarter. We did not repurchase any

stock during the quarter.

Revenue: SAN, Ethernet, and Global Services

SAN growth offset lower Federal Ethernet revenue

2011 Brocade Communications Systems, Inc.

Page 22 of 41

Turning to revenues by business unit, our Storage product revenue was $331.2M in the quarter, an increase of 4.9%

sequentially. Storage represented 61% of revenues in Q1 versus 57% in Q4.

Our Ethernet product revenue was $126.1M in the quarter, a decrease of 11.5% sequentially. Ethernet product revenue

represented 23% of total revenue versus 26% in Q4.

Our Global Services revenue was $88.7M in the quarter and represented 16% of revenues, down slightly versus 17% in Q4.

Global Services revenue was down 3.6% sequentially driven primarily by lower Ethernet support revenue.

Looking at our Ethernet business, including hardware and Ethernet based support and services, Q1 revenues were

$153.2M up 23% Yr./Yr. and down 10% from our record quarter in Q4 10.

Our Federal Ethernet business was $20.4M, up 22% Yr./Yr. which was slightly higher than our previous guidance of $15-

20M for the quarter. Non-Federal Ethernet revenue was also up 23% Yr./Yr. showing strength across our product

portfolio and customer base. The non-Federal Ethernet business growth was driven by strong performances in our

international geographies led by the EMEA region. We saw good growth in our new accounts with both initial sales in the

quarter as well as new customers from previous quarters returning and buying again. We also saw strong demand for our

stackables in Q1, reaching a new record for Brocade for these products.

Looking at our SAN business, including hardware and SAN based support and services, Q1 revenue of $392.8M grew 3.4%

from Q4.

Demand for Brocade’s leading SAN products was strong resulting in SAN product revenue of $331.2M in the quarter, up

4.9% sequentially. Increases in revenue across our director and server product families drove the overall SAN increase

Qtr./Qtr. We generated the 2nd

highest revenue quarter for directors and a record revenue quarter for our Server product

group in Q1.

Our Server

product group, including Embedded Switches, HBA’s, and Mezzanine Cards, posted record revenues of

$48.7M which was up 7.0% Yr./Yr. and up 6.4% from a strong Q4. Embedded Switches were up 5.7% sequentially while

Higher mix of OEM revenue driven by overall mix to SAN business

2011 Brocade Communications Systems, Inc.

Page 26 of 41

In Q1, consistent with the prior quarters, Brocade had three customers that had revenue greater than 10%. EMC, IBM and

HP all contributed more than 10% of revenues individually. Collectively, our top three OEMs contributed 47% of revenues

in Q1, up from 44% in Q4, and down from 54% in the year ago quarter. Other OEMs represented 19% of revenues in Q1

versus 17% in Q4. We saw very good growth from HDS and Dell in the quarter which drove this metric higher sequentiall

Channel and Direct were 34% of revenues in Q1, a decrease from 39% in Q4, reflecting the overall mix away from

Federal Ethernet business in the quarter to SAN and the OEM routes to market.

Gross Margins: SAN strong; Ethernet down due to lower revenue

2011 Brocade Communications Systems, Inc.

Page 27 of 41

Non-GAAP Gross Margins of 62.0% were at the high end of our guidance range of 61.5% to 62.0% for the quarter driven

by the strong storage performance and down 30 basis points from Q4.

Q1 SAN gross margins, were 71.4% unchanged from Q4, reflecting a strong mix of director products that is typical in our

Q1. The higher mix of SAN products at an overall company level increased margins by approximately 75 basis points.

Q1 Ethernet non-GAAP gross margins were 46.7%, down from 47.8% in Q4. The lower Ethernet gross margins were

primarily driven by lower volumes in the quarter. The impact of lower Ethernet gross margins on overall company gross

margins was approximately -25 basis points in Q1. We continue to be focused on our Ethernet gross margin initiatives

outlined during our Analyst Day and expect to see improvements again in the 2nd half of 2011 to be within our Ethernet

gross margin target exiting the year.

Global Services non-GAAP gross margins were 48.7% in Q1, down versus 53.7% in Q4 due to lower revenue and mix to

lower margin support offerings. The impact of lower services gross margins on overall company gross margins was

approximately -80 basis points in Q1.

Page 28

of 41

On a non-GAAP basis, total operating expenses were 44.9% of revenues in Q1 versus 41.9% in Q4. Operating expenses

were better than our previous guidance range of 46% to 47% of revenues due, in part, to a slower hiring ramp than

planned as well as some project spending that moved out of the quarter. The dollar increase in operating expenses

sequentially reflects the investment in our sales organization made in Q4 as well as some additional investments in Q1.

We added 70 headcount in Q1, of which the majority was in Sales.

Non-GAAP operating margins were 17.1% in Q1, lower than our strong Q4 operating margins of 20.4% due to higher

operating expenses and slightly lower gross margins in the quarter. Our 2-year target range of operating margins is 17%

to 20% and we plan to be at the low end of that range for the full year.

Cash from operations was over $118M in Q1, our highest level since Q4 09 and better than our previous guidance.

Total capital expenditures in the quarter were $23M. Free cash flow was nearly $95M in the quarter, again the highest

since Q4 09. Capital spending on the Company campus fell to approximately $2M in the quarter, reflecting the

completion of the project with only minor final payments remaining through Q3 11.

Cash and equivalents grew to $416M, up $80M from $336M in Q4. In Q1, we reduced our debt principal by $39.7M

including $30.0M in excess of the mandatory payment.

As we stated during our Analyst Day, we continue to focus on increasing operating cash flow and our priorities for

cash will be focused on paying down our term debt first, continuing to build our cash reserves, and repurchasing stock

on an opportunistic basis and subject to debt covenants.

Net Debt has declined from $1,073M at the end of Q1 09 to $503M at the end of Q1 11. This represents a $570M or 53%

reduction over the last two years, demonstrating Brocade’s ability to generate cash and reduce our long-term debt. Our

term debt loan balance is now down to $311M.

Adjusted EBITDA in the quarter was $114.5M, which was down from the Q4 level of $127.7M. The Senior Secured

Leverage Ratio of 2.00x and the Fixed Charge Coverage Ratio of 1.80x are both within the covenant requirements of our

term credit agreement.

Q2 2011 Planning Assumptions

IT market conditions

•

Macro economic conditions improving

•

Strength building in international IT spending

•

Federal spending improving

•

SAN revenue slightly better than typical seasonality

•

Expect to grow at least with market in Ethernet

ASP trends

•

Low single-digit declines in SAN pricing

•

Low to mid single-digit declines in Ethernet pricing

Taxes

•

Outlook tax rate does not include discrete items

•

Outlook tax rate includes R&D tax credit

OEM inventories

•

Expect to come down slightly exiting Q2

2011 Brocade Communications Systems, Inc.

Page 31

of 41

Now, as we look forward to Q2 11, here are some things to consider in developing your financial models:

•

We continue to look at GDP and IT spending forecasts for next quarter and this year. Our current GDP growth

assumptions have not changed since Analyst Day 2010 but we are seeing more positive signs as we enter our Q2.

•

We continue to monitor the strength of international markets, specifically Europe and Japan, and expect to see

continued growth as these economies strengthen.

•

We are mindful of the

ongoing

Federal budget discussions but believe that we will see an improvement in the Federal

spending in Q2.

•

Q2 SAN demand is historically down 6% to 8% and we expect Q2 11 revenue to be slightly better than historical

performance.

•

We continue to expect improvements

and growth in our Ethernet business as our new sales headcount becomes more

productive.

•

We anticipate that our new VDX and VCS products will continue to

ramp but will have minimal impact to revenue/gross

margin in Q2.

•

We expect quarterly ASP declines in our SAN business to remain in the low-single digits. ASP declines in our Ethernet

business are expected to be in the low to mid-single digits.

•

From a tax rate perspective, we do not forecast discrete events due to the inherent uncertainty of their timing, but have

reflected the benefit of the passage of the R&D tax credit in our full year tax rate.

•

Regarding OEM inventory, we would expect OEM inventory levels to

be flat to a slight decline in absolute dollar terms

exiting Q2, given that we are in our seasonally

softer quarters.
