2-Port 40 Gb InfiniBand Expansion Card (CFFh) for BladeCenter

The 2-Port 40 Gb InfiniBand Expansion Card (CFFh) for 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.

Figure 1 shows the expansion card.

InfiniBand is a scalable high performance fabric that was used for Petascale computing. Roadrunner is the largest supercomputer of the world, breaking the barrier of 1000 trillion operations per second. Roadrunner is based on Mellanox ConnectX DDR adapters. QDR is the next generation, which offers twice the bandwidth per port.

BladeCenter chassis support is based on the blade server type in which the expansion card is installed. Consult ServerProven to see which chassis each blade server type is supported in: http://ibm.com/servers/eserver/serverproven/compat/us/.

Table 3 lists the I/O modules that can be used to connect to the 2-Port 40 Gb InfiniBand Expansion Card (CFFh) for BladeCenter. The I/O modules listed in Table 3 are supported in BladeCenter H chassis only.

Voltaire 40 Gb InfiniBand Switch Module	46M6005	N	N	Y	N	N	N	N

In BladeCenter H, the ports of CFFh cards are routed through the midplane to I/O bays 7, 8, 9, and 10, as shown in Figure 3.

Figure 3. BladeCenter H I/O topology showing the I/O paths from CFFh expansion cards

One I/O module must be installed in the chassis for each 4X InfiniBand port that you wish to use on the expansion card. The specific I/O bays in the chassis are listed in Table 4. For the 2-Port 40 Gb InfiniBand Expansion Card (CFFh), you should install an I/O module in I/O bays 7/8 and 9/10 (that is, two I/O modules, each of them occupies two adjacent high-speed slots).

Table 4. Locations of I/O modules required to connect to the expansion card

* A single Voltaire 40 Gb InfiniBand Switch Module occupies two adjacent high-speed bays (7 and 8 or 9 and 10) while expansion cards have only two ports--one port per one InfiniBand module.

Figure 4 shows the use of Voltaire 40 Gb InfiniBand Switch Module to route two 4X InfiniBand ports from 2-Port 40 Gb InfiniBand Expansion Card (CFFh) installed into each server. Two Voltaire 40 Gb InfiniBand Switch Modules are installed in bays 7/8 and bays 9/10 of the BladeCenter H chassis. All connections between the expansion cards and the switch modules are internal to the chassis. No cabling is needed.
