Voltaire Ltd. (NASDAQ: VOLT), a leading provider of scale-out data center fabrics, today announced that its switches provide the server-to-server or server-to-storage interconnect fabric for 55 percent of the InfiniBand deployments on the 35th edition of the TOP500 list of the world’s most powerful supercomputers released this week. This represents more than double the share of any other InfiniBand systems vendor. In addition, Voltaire switches are used in 33 new entries on the list since November 2009, bringing Voltaire’s total count to 114.

InfiniBand was the only interconnect technology to grow share on the new list with 37% annual growth from June 2009 to June 2010. Voltaire 20 and 40 Gb/s InfiniBand switches provide the high performance interconnect fabrics for the world’s top research institutions on the list, as well as for commercial and industrial customers who rely on HPC technologies to run their businesses. Voltaire switches accelerate 27 of the Top 100 systems – including 3 of the Top 10 – and also comprise the high-performance fabric for 83 percent of the commercial sites that use InfiniBand.

“Voltaire’s InfiniBand solutions are known for their industry-leading performance and scalability, as well as for their ultra-low latency which dramatically accelerates performance for demanding HPC and enterprise data center applications,” said Asaf Somekh, vice president of marketing, Voltaire. “The new TOP500 list reflects Voltaire’s continued leadership in the InfiniBand switching market with more deployments than any other InfiniBand switch vendor.”
