Enterprise Strategy Group (ESG) Labs Report Validates NetApp® Data ONTAP™ and V-Series Capabilities

Sunnyvale, Calif. - October 26, 2005 - Network Appliance, Inc. (NASDAQ: NTAP), a leading provider of enterprise network storage solutions, today announced that ESG Labs has released a validation report on NetApp Data ONTAP 7G and V-Series systems. ESG Labs' hands-on testing demonstrated improved manageability, performance, and capacity utilization of NetApp FlexVol™ and FlexClone™ software features. ESG Labs also tested the storage virtualization capabilities of the NetApp V-Series with third-party storage systems from IBM and HDS.

Key findings included in the ESG Lab report:

  • NetApp FlexVol thin provisioning enables customers to get much greater capacity utilization and significantly simplifies storage provisioning. ESG believes that thin provisioning is one of the most useful capabilities provided by a storage system from which most, if not all, customers can benefit.
  • ESG Lab testing showed a 44% improvement in performance using FlexVol versus traditional volume performance.
  • NetApp provides an excellent midrange SAN-based storage system that can compete with any of the leading midrange solutions currently available.
  • The NetApp unified approach simplifies management and reduces costs by providing one system versus two, with all of the associated software licenses and maintenance fees.
