               BROCADE CITES OPERATIONAL PROGRESS AND GROWTH PLANS

         New Product Cycle and Optimized Organization Set to Accelerate

                    Targeted Financial Performance and Growth

SAN JOSE, CALIF. -- MAY 19, 2004 -- Brocade Communications Systems, Inc.
(Brocade(R)) (Nasdaq: BRCD), today followed its second quarter financial results
by outlining the next phase of its operational and organizational plan for long
term leadership in the Storage Area Network (SAN) infrastructure market.
Building on its continued positive financial performance, improved operating
efficiency and successful new product development programs, the company is
further optimizing its business model and aligning its organization to
accelerate profitability and improve revenue growth.

"Today Brocade announced its fifth consecutive quarter of improved financial
performance, confirming our belief that growth in the network storage market is
sustainable for companies that offer compelling and competitive products to
their trusted OEM partners and value to the end customer," said Greg Reyes,
Brocade Chairman and CEO. "We are also seeing the positive results of our
strategic plan to achieve market leading positions across the entire spectrum of
the SAN market, while optimizing our business model for increased shareholder
value."

The organizational alignment, being implemented immediately, will result in
greater efficiencies and streamlined operations, a more leveraged development
model, a consolidated sales organization optimized for more in-depth coverage,
and a more customer-focused marketing organization. As a result of the actions
announced today, Brocade reduced its workforce by 110 employees, or 9%, and
incurred a $10.5 million restructuring charge for severance, asset impairments
and contract terminations.

                                                                          PAGE 2


"The majority of the measures we are taking are structural but, unfortunately
there are some valued employees that will be affected," continued Reyes. "I feel
confident that all of these actions combined, place Brocade in its best
competitive position in over two years - strategically and operationally - and
will result in a healthier and more leveraged business model with room to invest
for future growth."

In its second fiscal quarter earnings announcement (see today's press release:
"Brocade Reports Second Quarter of Fiscal 2004 Results"), Brocade noted that it
had successfully launched new product platforms for the entry-level, mid-range
and enterprise market, as well as the emerging bladed server market segment.
This is the largest rollout of new products in the company's history. With these
expanded product introductions completed, Brocade's SAN switch offerings now
operate on a common software code base and shared hardware architecture,
resulting in significant efficiencies in product development. These
efficiencies, continuing improvements in processes, and ongoing cost reduction
programs enable Brocade to streamline product design and development to the
benefit of our shareholders.

The company also announced that it is combining two previously distinct sales
teams, the first one focused on OEM partners and the other on end-users and
channel partners-into one organization going forward. Michael Klayko, formerly
Brocade VP, Marketing and Support, has been appointed to lead the combined sales
organization with focus on increasing coverage, agility, and operational
efficiencies of the company's go to market model with a renewed focus on revenue
growth.
