Mellanox InfiniBand enables the highest system efficiency and utilization, up to 96 percent.

Mellanox logoMellanox’s end-to-end 40Gb/s connectivity provides the most scalable, reliable, and highest performance solution for demanding compute applications around the world delivering not only the highest return on investment, but also the lowest power consumption,” said Eyal Waldman, president, chairman and CEO of Mellanox Technologies. “We are experiencing the growth of InfiniBand in the high-performance computing markets and are now seeing its adoption in additional markets such as financial, database, virtualized data centers, Web 2.0 and Cloud Computing.
