Mellanox ConnectX-2 40Gb/s InfiniBand Adapters with Application Communication Offloading Technology Available Through HP

ConnectX®-2 InfiniBand Adapters with New CORE-Direct™ (Collectives Offload Resource Engine) Capabilities Provide Clusters with Application Acceleration and Enhanced Scaling

SC09, PORTLAND, OR. – Nov. 16, 2009 – Mellanox® Technologies, Ltd. (NASDAQ: MLNX; TASE: MLNX), a leading supplier of end-to-end connectivity solutions for data center servers and storage systems, today announced its industry-leading ConnectX-2 40Gb/s InfiniBand adapter cards are available now for HP ProLiant BL, DL and SL series servers, as well as HP BladeSystem c-Class enclosures. Mellanox’s ConnectX-2 40Gb/s InfiniBand adapter cards with CORE-Direct enable significant improvements in application performance and scalability and increase the productivity of HP-based compute clusters.

Mellanox ConnectX-2 is the first adapter card in the market to process in hardware application communications frequently used by scientific simulation for data broadcast, global synchronization and data collection. By offloading these collectives communication, ConnectX-2 adapters help to reduce simulation completion time by accelerating the synchronization process and freeing up CPU cycles to work on the simulation, thus enabling greater scalability by eliminating system jitter and noise.

“As supercomputers increase in size from mere thousands to hundreds-of-thousands of processor cores, new performance and scalability challenges have emerged,” said John Monson, vice president of marketing at Mellanox Technologies. “The combination of Mellanox ConnectX-2 40Gb/s InfiniBand adapters with CORE-Direct application interprocessor communication offload and HP ProLiant servers provide end-customers with the highest performance, efficiency and scalability for their next-generation, high-processor node count supercomputer.”

“Customers with high-performance computing clusters seek solutions to improve system efficiency and resource utilization, while still reducing overhead,” said Steve Cumings, director of marketing, Scalable Computing and Infrastructure organization, HP. “The combination of HP Unified Cluster Portfolio and Mellanox’s ConnectX-2 InfiniBand adapters can significantly enhance customers’ compute cluster application performance and scalability, while simplifying and speeding deployment.”

The advanced feature set combined with the highest I/O performance of any standard interconnect makes ConnectX-2 the leading interconnect adapter solution for high-performance server and storage computing infrastructures. Together with Mellanox world leading InfiniBand switch systems, FabricIT™ comprehensive switch management software and cables, Mellanox and HP provide its customers with the richest, most advanced and highest performing end-to-end networking solutions for the world’s most compute-demanding applications.
