Sunnyvale, Calif. - March 21, 2006 -- Network Appliance, Inc. (NASDAQ: NTAP) today announced its storage solutions will now support 4Gb Fibre Channel (FC). 4Gb FC combined with NetApp® unified storage systems and leading-edge data management software gives customers a compelling and powerful solution for managing large and ever growing amounts of data. NetApp 4Gb FC will allow its customers to increase the performance and availability of critical data and applications, while simplifying complex data management environments, improving productivity in application administration, and lowering storage costs.

NetApp SAN storage systems using 4Gb FC are ideally suited for customers that need to quickly develop, compute, transfer, or analyze large amounts of data, such as backup to disk, streaming video on demand, modeling and rendering, and large databases with extreme performance for faster time-to-solutions. The next-generation SAN technology gives customers the greater bandwidth performance they need, with no increase in price, and higher reliability due to a state-of-the-art interconnection technology that reduces the need for additional switch and host bus adapter ports.

"Given the growing and changing demand for data, customers require high-performance storage solutions to keep pace with their business needs," said Rich Clifton, vice president and general manager of the Networked Storage business unit. "NetApp support for 4Gb FC SANs demonstrates the ongoing commitment we make to our customers to deliver powerful solutions that help them to gain more value from their data infrastructure."

"NetApp is experiencing tremendous success with FC and they have an excellent SAN storage solution. It's interesting that NetApp is one of the first leading storage vendors to support 4Gb FC. It shows a commitment on the part of NetApp to constantly improve its SAN offerings," said Tony Asaro, senior analyst for the Enterprise Strategy Group.

Network Appliance provides comprehensive support for 4Gb FC SAN solutions for Solaris™ and in calendar Q2 2006 for Windows®, Linux®, AIX, HP-UX, VMware, and NetWare environments. In addition, NetApp sells or supports 4Gb HBAs from Emulex and Qlogic and 4Gb switches from Brocade, Cisco, and McData.
