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

IBM BladeCenter

IBM BladeCenter at-a-glance guide

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.

Figure 1 shows the expansion card.

Did you know?

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.

Figure 2 shows where the CFFh card is installed in a BladeCenter server. Figure 2. Location on the BladeCenter server planar where the CFFh card is installed IBM 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/.

Figure 3. IBM 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).

Popular configurations 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. Figure 4.
