NetApp Certifies Voltaire Grid Backbone™ High-Performance InfiniBand Switches

SuperComputing 2007, Reno, NV - November 12, 2007 -- Voltaire Ltd. (NASDAQ: VOLT), a leading provider of grid backbone solutions for the data center, today announced that NetApp has tested and validated Voltaire's InfiniBand-based Grid Backbone™ switches and software for customers who are seeking high-performance compute and storage solutions. The tested solution provides improved scalability and throughput that leverages the high bandwidth, low latency, and scalability of Voltaire InfiniBand with the scalability and flexibility of Network Appliance™ Inc. (NASDAQ: NTAP), modular storage architecture.

"NetApp® enterprise-class systems and software with Voltaire's 10-20 Gigabits/second InfiniBand solution provides customers improved throughput and scalability for their large cluster and grid environments and a highly scalable, modular storage solution," said Joel Reich, general manager and vice president, SAN and iSCSI Business Unit, NetApp. "We are pleased to work with Voltaire to provide customers high-performance, interoperable storage solutions."

NetApp has tested and validated Voltaire's Grid Director™ 10-20 Gigabits/second InfiniBand switches, IP routers, and GridStack™ InfiniBand host stack software on both the Linux® and Windows® operating systems. When combined with NetApp FAS systems, the solution alleviates one of the largest bottlenecks in large clustered environments: storage file I/O.

"Our recent user survey shows that clustered storage with a scale-out architecture is ranked number 4 in the list of 8 storage technologies and products to be adopted in the next 12 months," said Pushan Rinnen, research director, Gartner Research. "In many cases it's because clustered storage offers high parallel throughput in conjunction with a cluster file system. We are also seeing an increased interest in using InfiniBand interconnect technology to attack the storage file I/O bottleneck in large clustered environments."

"File I/O is one of the biggest challenges for data centers that use large clusters and grids to run their critical applications," said Asaf Somekh, vice president of strategic alliances, Voltaire. "By combining the performance and scalability of Voltaire's InfiniBand-based solutions with NetApp enterprise systems and software, that problem simply goes away. We look forward to working with NetApp on these much-needed interoperable solutions."
