Storage Networking World Recognizes APS, a NetApp Customer, with "Best Practices in Storage" Award

Sunnyvale, Calif. - April 14, 2006 -- Network Appliance, Inc. (NASDAQ: NTAP) today announced that its customer, Arizona Public Service (APS), has been honored by Storage Networking World (SNW), as a winner for the "Best Practices in Storage" awards in the Innovation and Promise category.

The award honors organizations that have applied exemplary storage networking solutions to provide strategic advantage to their enterprise. Recipients received recognition for their achievement during a special awards ceremony at SNW, an event co-owned by Computerworld, the "Voice of IT Management," and the Storage Networking Industry Association (SNIA), which was held from April 3 - 6, 2006, at the Manchester Grand Hyatt in San Diego, California.

"Companies recognized at SNW can be proud of the accomplishments of these talented IT professionals. Their hard work and dedication to the best practices in the storage networking industry benefit their companies, employees, and customers alike," said Ron Milton, executive vice president, Computerworld.

APS, Arizona's largest and longest serving electric utility in the southwest, manages over 150 terabytes of data across all its systems, with another 200 terabytes in secondary storage. Servicing one of the fastest growing regions in the United States, APS needed to upgrade its systems away from direct attached storage (DAS) to SAN systems. To do so, APS deployed a suite of NetApp® SAN solutions that allowed the company to grow as rapidly as its customer base, manage backups efficiently, keep its systems highly available, and protect sensitive customer data.

"We are honored to receive this award," said Mark Dillon, IS manager - Distributed Operating Systems at APS. "By deploying NetApp unified storage solutions, APS can scale quickly and reliably to meet the needs of our customers."
