Voltaire Renews OEM Contract with IBM Through 2010

Voltaire’s 20 Gigabits/second InfiniBand Products Now Available for IBM BladeCenter

BILLERICA, Mass. and HERZELIYA, Israel – February 13, 2008 – Voltaire Ltd. (NASDAQ: VOLT), a leading provider of grid backbone solutions for the data center, today announced that it has renewed the company’s OEM contract with IBM through 2010 and introduced two new products into the IBM BladeCenter product portfolio.

“IBM’s decision to continue and grow our relationship confirms the valuable role Voltaire’s products play in their server and bladed solutions portfolios,” said Ronnie Kenneth, CEO and Chairman, Voltaire. “The renewal of our contract through 2010 is significant in terms of future revenue potential for Voltaire.”

IBM now offers a pass through module that interoperates with Voltaire InfiniBand DDR and a host channel adapter with Voltaire GridStack™ software as an interconnect option for IBM BladeCenter. The IBM pass through module is the only 20 Gigabits/second I/O module currently available in the IBM BladeCenter portfolio and the only 20 Gigabits/second blade I/O module in the industry that leverages Voltaire’s unique InfiniBand pass through design.

The Voltaire products provide high bandwidth, low latency connectivity for IBM blade servers, creating a solution that is ideal for scaling out and virtualizing data center infrastructure.

“IBM BladeCenter using Voltaire InfiniBand brings excellent performance for enterprise environments, particularly those using virtualization technologies that require high speed I/O and are looking to improve application performance,” said Alex Yost, vice president, IBM BladeCenter. “Our inclusion of Voltaire InfiniBand in our BladeCenter solution is part of IBM’s ongoing strategy to strengthen the BladeCenter platform with a diverse set of adapter, switch and connection technologies that meet a broad set of customer requirements.”

IBM also offers Voltaire Grid Director™ switches, routers and software as part of the Cluster1350 solution portfolio.

InfiniBand and Blades for Financial Services

Financial services firms have been quick to deploy IBM BladeCenter with Voltaire InfiniBand as a way to improve performance of applications for advanced trading and market data, including IBM’s WebSphere MQ Low Latency Messaging software. The combined solution enables firms to deploy a trading infrastructure that is optimized for high message throughput, low latency and efficiency. In a recent IBM benchmark, IBM’s WebSphere MQ Low Latency Messaging software was able to deliver 300% more messages per second and had 50% lower latency running on Voltaire InfiniBand than on Ethernet.(1)

Note to editors:

(1) WebSphere MQ Low Latency Messaging has demonstrated very high throughput, one-to-many multicast messaging, which can deliver approximately one million 120-byte messages per second on Ethernet, close to three million 120-byte messages per second on InfiniBand, and more than 8 million smaller messages per second, all on common x86 servers. Testing has also measured very low latency of 30 microseconds for 120 byte messages delivered at 10,000 messages per second on InfiniBand or 61 microseconds on Ethernet.

The stated performance numbers are based on measurements using standard IBM benchmarks in a controlled environment. The actual throughput that any application will experience may vary depending upon considerations such as message size, transmission rate, hardware platform, and network configuration.
