Network Appliance™ Storage Delivers 60% Lower TCO for Data Consolidation in Microsoft® Windows® Environments

Sunnyvale, CA - April 23, 2002 -- Network Appliance, Inc. (NASDAQ: NTAP), a leading provider of enterprise network storage solutions, today announced that a new INPUT study found that Network Appliance offers over 60% lower total cost of ownership (TCO) for data storage consolidation in Microsoft Windows environments, versus competing storage area network (SAN) solutions from Compaq. The INPUT study indicated that the impetus for data storage consolidation was upgrading to a newer version of Microsoft Windows, and when doing so, Network Appliance solutions were easier to deploy, required fewer staff to manage, and provided high levels of data availability compared to Compaq® storage solutions.

Network Appliance also offers greater data management features, including Snapshot™ technologies and DataFabric™ Manager, centralized management software that enables system administrators to focus more of their time on proactive tasks rather than routine maintenance. Overall, customers rated Network Appliance higher in reliability, availability, manageability, scalability, and ease of deployment.

"This study indicates that enterprises upgrading to the newest version of the Windows Server family benefit considerably from data consolidation and shows that Network Appliance delivers significantly lower total cost of ownership compared to Compaq," said Sara Wells, senior research analyst at INPUT. "Based on the analysis, Network Appliance delivered 60% lower TCO by enabling customers to architect solutions that require less implementation time and require 25% fewer staff to manage."

"Businesses today must manage rapid data growth with fewer IT resources while also ensuring 24x7 data availability. NetApp storage solutions are designed to simplify management and minimize downtime, and deliver significantly lower total cost of ownership than comparable storage offerings," said Ray Villeneuve, vice president of marketing at Network Appliance. "These are true business benefits, and distinguish Network Appliance as a customer favorite."

The study analyzed a large number of Microsoft Windows data consolidation implementations and evaluated a broad spectrum of criteria, including product implementation, operation, and business downtime costs both internally and externally, that are useful for evaluating how competing storage solutions fare in real-world enterprise environments.
