Mellanox Doubles InfiniBand Performance W/ 20, 60Gbps Technology
Mellanox Technologies will demonstrate new double data date (DDR) 20Gbps and
60Gbps InfiniBand technology at the Supercomputing 2004 conference in
Pittsburgh. InfiniBand DDR technology provides twice the bandwidth delivered
by current InfiniBand products and achieves up to eight times the performance
of competing interconnects. The technology demonstration is welcome news for
data centers and supercomputer architects looking to deploy bandwidth-hungry
applications on 64-bit platforms. The demonstration also highlights the
significant return on investment of deploying InfiniBand, as the new 20Gbps
and 60Gbps solutions are backwards compatible with existing software and
hardware.
"InfiniBand has clearly enabled a Moore's law effect for interconnects," said
Michael Kagan, vice president of architecture at Mellanox. "While competing
technologies are struggling to introduce 10Gbps technologies, InfiniBand is
doubling the speed of its existing architecture without requiring new
software. This positions InfiniBand as the highest performance and best
technology choice for 64-bit and dual core platforms in business and technical
computing."
The technology demonstration consists of a complete 8-node Dual Processor
Intel Xeon EM64T cluster with InfiniBand PCI Express Adapters and an
InfiniBand Switch with both 20Gbps and 60Gbps ports. The adapters use the
Mellanox InfiniHost III Ex PCI Express device, and the switch is based on the
24-Port InfiniScale III device. The demonstration runs a Computational Fluid
Dynamics application from Fluent Inc and the latest Linux IBGold software
package from Mellanox.
20Gbps technology is only one in a series of speed upgrades in the InfiniBand
roadmap. In September, the InfiniBand Trade Association (IBTA) released a
final version of the Annex, which specifies DDR and QDR (Quad Data Rate) modes
of operation. These modes define increased signaling rates over existing 1X,
4X and 12X InfiniBand links, effectively doubling or quadrupling bandwidth
using the same infrastructure. For example, DDR operation over 4X and 12X
InfiniBand links provides 20Gbps and 60Gbps respectively, as will be
demonstrated in the Mellanox booth at SC2004.
Mellanox will begin sampling Switch and HCA silicon in Q4, 2004. DDR Switches
and PCI Express HCA Adapter cards are scheduled for availability in the first
half of 2005.
