Rackable unveils servers with 40Gbit/s InfiniBand

Servers are based on Intel's Xeon 5500 series Nehalem processors

Rackable Systems has announced new SGI x86 servers with both Quad Data Rate (QDR) InfiniBand and 10Gbit/s Ethernet connections, which the company claims as a first in this market.

Available immediately, the new servers extend Rackable's server lines, including its CloudRack series. The QDR (40Gbit/s) InifinBand capability is provided via a new adapter chip from Mellanox Technologies integrated onto the motherboard.

All the new systems are based on Intel's Xeon 5500 series Nehalem processors at clock speeds up to 3.2GHz, and are available in memory capacities up to 96GB of DDR3.

According to Rackable, the new systems provide a superior connectivity solution for high-performance computing.

"Our upgraded Rackable servers are optimised to manage a complex workflow and allow applications to attain high performance without the I/O bottlenecks associated with higher latency and lower bandwidth solutions," said SGI senior vice president Giovanni Coglitore.

Rackable Systems acquired SGI earlier this year, and adopted the SGI brand name.
