NetApp FC SAN Solution Is the Right Prescription for the Immune Tolerance Network Consortium

Sunnyvale, Calif. - October 9, 2007 -- Network Appliance, Inc. (NASDAQ: NTAP), a leader in advanced networked storage solutions, today announced that the Immune Tolerance Network (ITN), an international collaboration of researchers who conduct clinical research of new immune tolerance therapies, has deployed a NetApp unified storage platform to improve data access and availability as well as provide new levels of security for mission-critical research data. The new NetApp system enables scholars around the world to study and share the latest breakthroughs in immune therapies and target effective strategies for combating human diseases.

To dramatically enhance its IT storage infrastructure, ITN deployed VMware Infrastructure across 30 physical servers and NetApp Fibre Channel SAN storage to replace direct attached storage. ITN used a pair of clustered NetApp FAS3000 series systems running Data ONTAP® 7G and SyncMirror® in their primary site in Herndon, Virginia. These systems then used cost-effective business continuity solutions by using SnapMirror® in the DR site in San Francisco, California. ITN used VMware Infrastructure to fully virtualize their production server and storage environment, which now consists of 150 virtualized servers and NetApp FlexVol® and NetApp FlexClone®. These solutions provide ITN the flexibility to rapidly allocate compute and storage resources, as well as data stores, to support new research activities with no additional storage or administrative overhead. The virtualized storage environment with FlexVol truly complements the virtualized server environment that VMware Infrastructure provides to get the maximum ROI from IT. Additionally, NetApp backup and disaster recovery solutions, including Snapshot™, SnapMirror, and SnapRestore®, further safeguard data in the event of data loss or disaster.

"The ROI on the NetApp solution has been dramatic," said Michael Williams, executive director of IT, Immune Tolerance Network. "All of the data, for tens of thousands of specimens and samples that we've collected, is stored on NetApp, and these systems are accelerating research into measurable results for more effective medical treatment of diseases like diabetes and live organ transplantation. NetApp allows us to scale with the expanding requirements of research activities to deliver ever greater value for our funding dollars."

"NetApp is honored to be the backbone of ITN's centralized storage and virtualization architecture," said Patrick Rogers, vice president of Solutions Marketing at Network Appliance. "ITN is a leader in the medical research field and NetApp has accelerated its position in this space by offering scalable, cost-effective, and easy-to-manage storage solutions that meet the constant demands of the research community."
