InfiniBand Momentum on the Top500 Continues with 25% Annual Growth, All with Mellanox Performance-Leading Interconnect Solutions

ISC’09, HAMBURG, GERMANY – June 23, 2009 – Mellanox® Technologies, Ltd. (NASDAQ: MLNX; TASE: MLNX), a leading supplier of high-performance, end-to-end connectivity solutions for data center servers and storage, today announced that its InfiniBand adapters and switch solutions enables the highest system efficiency and utilization as reported in the 33rd edition of the TOP500 list. Mellanox InfiniBand demonstrates up to 94 percent system utilization, only 6 percent under the theoretical limit, providing users with the best return on investment for their high-performance computing server and storage infrastructure known in the industry. This year’s TOP500 list reveals that InfiniBand is the only growing industry-standard interconnect solution, increasing 25 percent to 152 systems, representing more than 30 percent of the TOP500.

Mellanox ConnectX® InfiniBand adapters and switch systems based on its InfiniScale® III and IV switch silicon provide the scalable, low-latency, and power-efficient interconnect for the world’s fastest supercomputer and the majority of the top 100 systems. Mellanox end-to-end 40Gb/s InfiniBand solutions deliver the leading performance and highest Top10 system efficiency in the 10th ranked Jülich cluster.

The total number of InfiniBand-connected CPU cores on the TOP500 list has grown 72 percent, from 606,000 in 2008 to 1,040,000 in 2009. This highlights increasing demand for InfiniBand as a way to maximize computing resources, productivity and performance in the world’s fastest computer systems.

“Mellanox’s end-to-end 40Gb/s connectivity provides users with the most efficient solution for high-performance systems, and maximizes the compute resource utilization, offering not only the highest return on investment known in the industry, but also the lowest power/usage consumption, too,” said Eyal Waldman, president, chairman and CEO of Mellanox Technologies. “As the most reliable, scalable, power efficient and highest performing InfiniBand solutions leader, Mellanox connectivity products continue to support the ever-increasing performance demands and efficiency needs of world-leading research facilities, educational centers, cloud computing, and green data centers.”

Published twice a year and publicly available at, the TOP500 list ranks the world’s most powerful computer systems according to the Linpack benchmark rating system. The TOP500 list is a respected industry report that indicates usage trends in computing and interconnect solutions.
