PORTLAND, Ore.--(BUSINESS WIRE)--Voltaire Ltd.

With 181 sites, InfiniBand interconnect technology continues to increase share on the TOP500 list at the expense of Gigabit Ethernet.

Voltaire switches accelerate 20 of the Top 100 systems -- including 2 of the Top 5 -- and also comprise the high-performance fabrics for 90 percent of the commercial sites that use InfiniBand. Voltaire switches are used in 40 new entries on the list since June 2009.

“Voltaire is known for delivering high performance, scale-out fabrics to the world’s largest supercomputers and to the data centers of the world’s largest corporations,” said Asaf Somekh, vice president of marketing, Voltaire. “This new list confirms that we are widening our lead in the InfiniBand switching market with more deployments than any other InfiniBand switch vendor.”
