InfiniBand Boasts Growth

DRESDEN, Germany -- Mellanox Technologies, Ltd. (NASDAQ:MLNX), a leading supplier of semiconductor-based, server and storage interconnect products, announced today that InfiniBand continues to be the fastest growing cluster interconnect according to the 29th edition of the TOP500 list of the world’s most powerful computers. 132 supercomputers (26% of the list) are connected with InfiniBand, 230% more than the 40 supercomputers on the June 2006 list, and 61% more than the 82 supercomputers reported on the November 2006 list.

InfiniBand-based clusters continue to take share from clusters using Ethernet and proprietary interconnect solutions as industry-standard InfiniBand is proven to deliver higher scalability, efficiency and performance, especially when connecting multi-core computing servers and storage systems. In particular, 20Gb/s InfiniBand usage on the list has increased significantly to 55 clusters from only a single cluster 6 months ago which highlights the fast adoption of 20Gb/s performance.

Published twice a year and publicly available at Top500.org, the TOP500 list ranks the most powerful computer systems according to the Linpack benchmark rating system and is an industry respected report which indicates usage trends in computing and interconnect solutions. Highlights of InfiniBand usage on the June 2007 TOP500 list include:

• All InfiniBand-based clusters utilize Mellanox switch silicon and well over 95% integrate adapters products based on Mellanox silicon
• 8 of the top 20 most prestigious positions use InfiniBand – all based on Mellanox adapter cards and switch silicon
• InfiniBand is the most used high-speed, low-latency interconnect and has the greatest increase in the rate of usage, used by 26% of the list
• The average efficiency of all reported InfiniBand-based supercomputers is 71% -- significantly higher than the average efficiency of Gigabit Ethernet connected clusters at 54%
