            REVENUES INCREASE 5% SEQUENTIALLY AND 18% YEAR OVER YEAR

SAN JOSE, CALIF. -- FEBRUARY 11, 2004 -- Brocade Communications Systems, Inc.
(Brocade(R)) (Nasdaq: BRCD) reported today financial results for its first
quarter of fiscal year 2004 (Q1 04) which ended January 24, 2004. Net revenues
for Q1 04 were $145.0 million, an increase of five percent from $137.8 million
reported in the fourth quarter of fiscal year 2003 (Q4 03) and an increase of 18
percent from $123.1 million reported in the first quarter of fiscal 2003 (Q1

"Our first quarter was a good one and fiscal 2004 is off to an excellent start
for Brocade. During the first quarter, we saw revenue growth across our entire
business," said Greg Reyes, Brocade Chairman and CEO. "This represents our 4th
quarter in a row of improved revenue, gross margin and operating margin. With
our upcoming product cycle and improving trends in the storage sector, we
continue to be confident in our market position and future prospects."

Non-GAAP net income for Q1 04 was $8.0 million, or $0.03 per share, as compared
to non-GAAP net income of $4.6 million, or $0.02 per share, reported in Q4 03
and non-GAAP net income of $0.0 million, or $0.00 per share, reported in Q1 03.
Non-GAAP net income for Q1 04 excludes gains related to repurchases of
convertible subordinated debt, deferred stock compensation expense related to
the acquisition of Rhapsody Networks, Inc. (Rhapsody), and lease termination,
facilities consolidation and other related costs. Non-GAAP net income for Q4 03
excludes gains related to repurchases of convertible subordinated debt, a gain
on the disposition of private strategic investments, a reduction of previously
recorded restructuring costs, and deferred stock compensation expense related to
the acquisition of Rhapsody. Non-GAAP net income for Q1 03 excludes net gains on
the disposition of private strategic investments and restructuring costs
associated with a company-wide workforce reduction in Q1 03. A reconciliation

The non-GAAP, formerly pro forma, information provided in this press release is
a supplement to, and not a substitute for, our financial results presented in
accordance with GAAP. The non-GAAP results exclude certain expenses and income
to provide what we believe is a more complete understanding of our underlying
operational results and trends. Specifically, we believe the non-GAAP results
provide useful information to both management and investors by excluding the
gain related to repurchases of our convertible subordinated debt, net gains on
the disposition of private strategic investments, certain expenses relating to
our acquisition of Rhapsody, the restructuring of business operations and lease
termination, facilities consolidation and other related costs that we believe
are not indicative of our core operating results. Further, these non-GAAP
results are one of the primary indicators management uses for planning and
forecasting of future periods. Brocade management refers to these non-GAAP
financial measures in making decisions regarding operational performance and to
facilitate internal comparisons to historical operating results and to
competitors' operating results. Non-GAAP financial measures should be considered
in addition to results prepared in accordance with GAAP, but should not be
considered a substitute for or superior to GAAP results.

(*)   The non-GAAP, formerly pro-forma, information provided in this press
      release is a supplement to, and not a substitute for, our financial
      results presented in accordance with GAAP. The non-GAAP results exclude
      certain expenses and income to provide what we believe is a more complete
      understanding of our underlying operational results and trends.
      Specifically, we believe the non-GAAP results provide useful information
      to both management and investors by excluding the gain related to
      repurchases of our convertible subordinated debt, net gains on the
      disposition of private strategic investments, certain expenses relating to
      our acquisition of Rhapsody, the restructuring of business operations and
      lease termination, facilities consolidation and other related costs that
      we believe are not indicative of our core operating results. Further,
      these non-GAAP results are one of the primary indicators management uses
      for planning and forecasting of future periods. Brocade management refers
      to these non-GAAP financial measures in making decisions regarding
      operational performance and to facilitate internal comparisons to
      historical operating results and to competitors' operating results.
      Non-GAAP financial measures should be considered in addition to results
      prepared in accordance with GAAP, but should not be considered a
      substitute for or superior to GAAP results.

(a)   Deferred stock compensation related to the acquisition of Rhapsody.

(b)   Severance and related benefits, asset impairment charges, and contract
      termination charges related to the restructuring of business operations.

(c)   Lease termination, facilities lease losses and other related costs related
      to a building purchase and facilities consolidation.

(d)   Gain on repurchases of convertible subordinated debt.

(e)   Net gains on the disposition of private strategic investments.

(f)   Income tax effects associated with non-GAAP adjustments.
