Mellanox ConnectX IB InfiniBand Mezzanine Adapters Accelerate HP BladeSystem c-Class

HP First to Integrate Industry-Leading Adapter for Multi-Core, High-Density Blade Clustering Applications

SANTA CLARA, CA. and YOKNEAM, ISRAEL – July 9, 2007 Mellanox™ Technologies, Ltd. (NASDAQ: MLNX; TASE: MLNX), a leading supplier of semiconductor-based, server and storage interconnect products, today announced that the company’s 20Gb/s ConnectX IB InfiniBand mezzanine cards provide the optimal performance interconnect for HP BladeSystem c-Class.

“Mellanox’s ConnectX IB InfiniBand adapters provide unparalleled I/O connectivity for high-throughput and latency-sensitive clusters, grids and virtualized environments,” said Eyal Waldman, chairman, president and CEO of Mellanox Technologies. “HP BladeSystem c-Class is an ideal platform for high-performance computing clusters and we’re proud that our InfiniBand adapters have been integrated with it.”

A Mellanox ConnectX IB 20Gb/s InfiniBand mezzanine card adapter can reside on each server blade in the BladeSystem enclosure to provide high-performance connectivity to the processor through a PCI Express interface. InfiniBand signals are carried over a midplane that supports 5 Terabits per second of aggregate bandwidth to InfiniBand switch modules that plug into high-speed switch bays. Each ConnectX IB mezzanine card adapter supports two ports and can connect to two independent switch modules for redundancy and higher aggregated bandwidth – capabilities that are useful for mission-critical applications and the most-demanding HPC deployments.

“The HPC market is seeing increased demand for industry standards-based clusters such as those based on the HP BladeSystem c-Class, which offers great performance, consumes less power, and lowers total cost of ownership,” said Winston Prather, vice president and general manager, High Performance Computing Division, HP. “The Mellanox InfiniBand mezzanine cards further build on the leadership I/O capabilities of the HP BladeSystem c-Class, providing superior connectivity that enables increased HPC productivity.”

The ConnectX IB mezzanine card is available for purchase now. The mezzanine card has been tested with OFED 1.2.c. The HP-supported software stacks for HPC applications (including HP-MPI) will be available later this quarter.
