Network Appliance Ranked in DM Review’s Top 100 Companies List for Fifth Straight Year

Sunnyvale, Calif. - November 18, 2004 -- Network Appliance, Inc. (NASDAQ: NTAP) was honored by DM Review as one of the top 100 companies in the business intelligence space, as determined by DM Review readers. This marks the fifth consecutive year that the innovative storage leader has appeared on the list. The DM Review 100 ranking is based upon product quality, market share, and overall customer satisfaction.

DM Review will highlight the company in its December 2004 edition with an interview with Daniel J. Warmenhoven, CEO at Network Appliance.

"Over the last year, enterprise customers have embraced our Storage Grid vision and recognized the need for storage solutions that manage, store, access, and protect their different categories of data," said Patrick Rogers, vice president of Solution and Alliance Marketing at Network Appliance. "This continued recognition by DM Review further validates how NetApp solutions solve customers' management needs for tier-one data application environments plus address their backup, archival, restore, and reference data challenges."

DM Review 100 is determined based on the results of a product usage and vendor rating survey of readers conducted over the Web by The Gantry Group LLC. Survey respondents were presented with a questionnaire that examined more than 225 vendors in nine product categories. Respondents were asked to rank on a scale of 1 to 4 (1 = poor, 4 = excellent) each vendor whose products are in use in their organizations in each of the nine categories. Respondents were also asked to rank each vendor for overall customer service and satisfaction.
