SuperComputing shines spotlight on InfiniBand

SuperComputing 2009 is underway this week at Portland, and that means lots of InfiniBand news around products and OEM deals.

QLogic said today it has scored a string of OEM deals for its 40 Gbps InfiniBand devices, bringing its 7300 Series host channel adapters (HCAs) and 1200 Director switches to the IBM System Cluster 1350, the HP Unified Cluster Portfolio, Dell PowerEdge servers and Precision workstations and SGI CloudRack Servers.

Voltaire disclosed its Vantage 8500 10-Gigabit Ethernet switch, Grid Director 4700 40 Gbps InfiniBand switch, and Unified Fabric Manager software are also available from HP as part of the HP Unified Cluster Portfolio.

Mellanox Technologies said its ConnectX-2 40 GBps InfiniBand HCAs are available now for HP ProLiant BL, DL and SL series servers, as well as HP BladeSystem c-Class enclosures. Mellanox also said it would have a 120 Gbps InfiniBand switch platform in 2010.

There’s a reason so much InfiniBand news is concentrated around SuperComputing – InfiniBand remains a niche interconnect for high performance computing due to its low latency and high bandwidth. That doesn’t mean the InfiniBand market won’t grow, but it’s unlikely to encroach on the turf of Fibre Channel, Ethernet or any converged networks in the data center.

QLogic director of corporate communications Steve Zivanic said his vendor has customers using InfiniBand, Fibre Channel and Ethernet, but InfiniBand stands on its own while the other protocols are beginning to converge around Fibre Channel over Ethernet (FCoE).

For instance, he says, financial institutions are looking to save power in the data center by consolidating with VMware, high density blade servers and FCoE. Some of those same firms use InfiniBand to run their Monte Carlo simulation programs on a separate network.

“People using InfiniBand don’t want to share anything,” Zivanic said. “They want dedicated bandwidth, 40 gigs per second. For high performance applications, people are increasing their presence of InfiniBand. On the other side of the house, for general business applications, that’s where we see FCoE brought in to reduce costs.”
