Voltaire Switches Accelerate Top 4 Supercomputers

Voltaire Limited’s switches are connecting the world’s most energy efficient supercomputers, according to the findings of the latest Green500 list announced by Green500.org.

Voltaire switches serve as the high-performance interconnect for the top 4 and 26 of the top 100 most energy efficient supercomputers on the list.

“Voltaire is known for delivering performance as evidenced by our InfiniBand leadership position on the TOP500 list of the world’s most powerful supercomputers," said Asaf Somekh, vice president of marketing, Voltaire. “This new Green500 list showcases Voltaire’s strength in delivering energy efficient fabrics for high performance systems. Voltaire’s unique combination of performance and efficiency is important for commercial data centers that need to reduce costs and energy usage without compromising on performance.”

Voltaire Grid Director InfiniBand switches deliver 20 or 40 Gb/s bandwidths and low latency with less than 5 watts per port power consumption.

“Insufficient power and cooling continue to dominate as the greatest data center facility problems,” said John Phelps, Research VP, Gartner. “In a recent poll of infrastructure and operations managers, combined power and cooling deficiencies were identified as the greatest data center facility problem for 67% of users.” (Gartner Research Note: Power and Cooling Remain the Top Data Center Infrastructure Issues, John Phelps, February 20, 2009, ID Number: G00165614)

The Green500 is a list ranking the most energy-efficient supercomputers in the world and serves as a complementary view to the Top500 list of the most powerful supercomputers.
