The 2-Port 40 Gb InfiniBand Expansion Card (CFFh) for IBM BladeCenter is a dual port InfiniBand Host Channel Adapter (HCA) based on proven Mellanox ConnectX IB technology. This HCA, when combined with the QDR switch, delivers end-to-end 40 Gb bandwidth per port. This solution is ideal for low latency, high bandwidth, performance-driven server and storage clustering applications in a High Performance Compute environment. The adapter uses the CFFh form factor and can be combined with a CIOv or CFFv adapter to get additional SAS, Fibre Channel, or Ethernet ports.
