  Network Appliance Announces Results for Fourth Quarter and Fiscal Year 2007

               Q4 Revenues $801.2 Million, up 34% Year over Year;

          Fiscal Year 2007 Revenues $2.8 Billion, up 36% Year over Year

     SUNNYVALE, Calif.--(BUSINESS WIRE)--May 23, 2007--Network Appliance, Inc.
(NASDAQ:NTAP), the leader in advanced networked storage solutions, today
reported results for the fourth quarter and fiscal year 2007. Revenues for the
fourth fiscal quarter were $801.2 million, an increase of 34% compared to
revenues of $598.0 million for the same period a year ago and an increase of 10%
compared to $729.3 million in the prior quarter.

     For the fourth fiscal quarter, GAAP net income increased 51% to $89.6
million, or $0.23 per share(1) compared to GAAP net income of $59.2 million, or
$0.15 per share for the same period in the prior year. Non-GAAP(2) net income
for the fourth fiscal quarter increased 28% to $114.2 million, or $0.30 per
share, compared to non-GAAP net income of $89.3 million, or $0.23 per share for
the same period a year ago.

     Revenues for fiscal year 2007 totaled $2.8 billion, an increase of 36%
compared to revenues of $2.07 billion for fiscal year 2006.

     For fiscal year 2007, GAAP net income increased 12% to $297.7 million, or
$0.77 per share, compared to GAAP net income of $266.5 million, or $0.69 per
share for fiscal year 2006. Non-GAAP net income for fiscal year 2007 increased
37% to $430.7 million, or $1.11 per share, compared to non-GAAP net income of
$315.3 million, or $0.81 per share for fiscal year 2006.

     "Network Appliance had a great finish to a great year. With 36% annual
growth, NetApp clearly provides to customers the best value in the industry,"
said Dan Warmenhoven, chief executive officer. "And while we weren't immune from
the March macroeconomic spending slowdown, our competitive differentiation and
business fundamentals have never been stronger."

     Outlook

     --   Network Appliance expects sequential revenue for the first quarter of
          fiscal year 2008 to decline by 6% to 7%, which translates to about 20%
          to 21% growth year over year.

     --   Including the implementation of SFAS123R and with current information
          and assumptions, the company estimates that the first quarter of
          fiscal year 2008 GAAP earnings per share will be approximately $0.14
          to $0.15 per share. Network Appliance expects first quarter non-GAAP
          earnings per share to be approximately $0.24 to $0.25 per share.

     Quarterly Highlights

     During the fourth quarter of fiscal year 2007, NetApp broadened its Fibre
Channel (FC) storage area network (SAN) portfolio and enhanced data management
and data protection solutions with new products as well as broader and deeper
partnerships. The company also continued to gain momentum in the SAN market
while maintaining market leadership in both network-attached storage (NAS) and
iSCSI.

     Continuing its extension into the data center, NetApp announced two new
midrange platforms aimed at making enterprise data center management easier for
customers. The NetApp(R) FAS3040 and NetApp V3040 series created additional
market opportunities for NetApp as it broadened its enterprise lineup and added
functionality for FC SAN environments.

     The NetApp FC SAN portfolio was further strengthened with the worldwide
availability of new switches, including two new blades for the Brocade(R) 48000
Director, and the QLogic(R) SANbox(R) 9000 Core and SANbox 5600 Stackable Series
of switches.

     NetApp expanded its enterprise-class software line with NetApp
ReplicatorX(TM) and NetApp SnapManager(R) software for use with SAP(R)
solutions. NetApp ReplicatorX (formerly Topio TDPS) provides continuous data
replication and recovery across a range of locations and storage systems,
including EMC, HDS, HP, IBM, and NetApp. NetApp SnapManager software for use
with SAP enhances application availability and provides increased storage
management flexibility in SAP environments.

     From a market perspective, according to IDC's Worldwide Quarterly Disk
Storage Systems Tracker Q4 2006(3), NetApp continued to grow faster than the
market in FC SAN in both revenue and capacity, year over year. The company grew
FC SAN revenue at more than seven times the rate of both the market leader and
the overall FC SAN market, and grew FC SAN capacity at more than four times the
rate of the overall market.

     In addition to FC SAN, NetApp continued to demonstrate leadership in the
NAS and iSCSI storage markets, maintaining the number-one market share position
in capacity shipped for NAS (38.9%) and in iSCSI for both capacity and revenue.

     NetApp also continued to show significant gains in storage software,
growing six times faster than the overall storage software market from 2005 to
2006, according to IDC's Worldwide Quarterly Storage Software Tracker Q4
2006(4).

     NetApp leadership in innovation remained strong with the news that it has
been positioned by Gartner, Inc., in the "Visionaries" quadrant in the Gartner
Magic Quadrant for Storage Resource Management (SRM) and SAN Management
Software, 2007(5).

     On the partner front, NetApp unveiled several new solution enhancements and
partner offerings with Brocade, Cisco, Fujitsu, Onaro, RSA, SAP, Symantec, and
VMware to address a variety of data concerns, including data management, data
protection, and data replication.

     In corporate news, NetApp topped the "Most Admired Company" list in the
computer peripherals industry in FORTUNE Magazine's 2007 "America's Most Admired
Companies" rankings.

     NetApp StoreVault(TM) S500 also received accolades in the fourth quarter as
it was voted "Best Product of the Year" in Small Business Computing's 2007
Product Excellence Awards.

     Network Appliance Usage of Non-GAAP Financials

     The Company refers to the non-GAAP financial measures cited above in making
operating decisions because they provide meaningful supplemental information
regarding the Company's operational performance. These non-GAAP financial
measures exclude amortization of intangible assets, in-process research and
development, stock compensation, other acquisition-related cost, restructuring
charges/recoveries, gain/loss on sales of assets and investments, certain other
nonrecurring events, and the related effects on income taxes as well as certain
discrete GAAP provisions for income tax matters recognized ratably for non-GAAP
purposes. We have excluded these items in order to enhance investors'
understanding of our ongoing operations. The use of these non-GAAP financial
measures has material limitations because they should not be used to evaluate
our company without reference to their corresponding GAAP financial measures. As
such, we compensate for these material limitations by using these non-GAAP
financial measures in conjunction with GAAP financial measures.

     These non-GAAP financial measures facilitate management's internal
comparisons to the Company's historical operating results and comparisons to
competitors' operating results. We include these non-GAAP financial measures in
our earnings announcement because we believe they are useful to investors in
allowing for greater transparency with respect to supplemental information used
by management in its financial and operational decision making, such as employee
compensation planning. In addition, we have historically reported similar
non-GAAP financial measures to our investors and believe that the inclusion of
comparative numbers provides consistency in our financial reporting at this
time.
