Voltaire Expands InfiniBand Leadership Position on Top500 List

Voltaire Switches Accelerate No. 1 Supercomputer Beyond a Petaflop

BILLERICA, Mass. and HERZELIYA, Israel – June 20, 2008 – Voltaire Ltd. (NASDAQ: VOLT), a leading provider of grid backbone solutions for data centers, today announced that it delivered more than 50 percent of the InfiniBand deployments on the 31st edition of the Top500 list of the world’s most powerful supercomputers released this week. Voltaire switches and software power 64 of the Top500 sites which represent 20 percent of the entire list’s total compute power.
In addition, Voltaire switches provide the high performance interconnect for NNSA/Los Alamos’ Roadrunner supercomputer, which is now the world’s most powerful supercomputer with performance greater than a petaflop.

“Voltaire solutions are delivering the interconnect performance needed to achieve a record-breaking petaflop of computing power for Los Alamos while simultaneously enabling customers in commercial industries to accelerate performance of business-critical applications,” said Asaf Somekh, vice president of strategic alliances, Voltaire. “Our customers on this new list represent leading companies in life sciences, automotive and manufacturing as well as top government and research institutions. We are pleased to advance our leadership position on the Top500 with more deployments than any other InfiniBand switch vendor.”

Voltaire Grid Director™ InfiniBand switches deliver 20 Gbps bandwidths and latencies of less than one microsecond to accelerate application performance by as much as 300% as compared to using Ethernet. Moreover, the switches’ power-efficient design offers lower power and cooling requirements as compared to 1 and 10 Gigabit Ethernet offerings.

Earlier this week, Voltaire announced plans to develop a 40 gigabits per second (Gbps)/quad data rate (QDR) switching platform with the first switches expected to be available in late 2008.

The Top500 list is published two times a year on www.Top500.org and ranks the most powerful supercomputers worldwide according to their performance on the LINPACK benchmark. The highly anticipated report provides a view into computing trends and technology adoption.
