26 Implementing Cisco InfiniBand on IBM BladeCenter

HCAs. However, there are plans to support both the existing Cisco 4X InfiniBand HCA, and

the Cisco 4X InfiniBand Switch Module. Check IBM ServerProven® for the latest support

2.7 Cisco SFS 3012R Multifabric Server Switch

While technically not part of the IBM BladeCenter H systems, the SFS 3012R is an important

component of any InfiniBand deployment, by offering Multifabric I/O (MFIO) to InfiniBand

clients.

Many users would like to be able to allow their InfiniBand clients access to Ethernet and Fibre

Channel networks, without the need to install Ethernet or Fibre Channel cards in their servers

or clients (or Ethernet and Fibre Channel switches into the BladeCenter H). Using a 3012R

with various gateway modules, it is possible to deploy servers and clients with only a single

connection to the InfiniBand fabric, full access to your Ethernet and Fibre Channel networks.

This results in simpler client configurations and cabling which can lead to reduced Total Cost

of Ownership (TCO).

Figure 2-7 shows an SFS 3012R fully loaded with 6 Fibre Channel gateways and 6 Ethernet

Gateways, two 12 port InfiniBand cards and redundant controllers. Note that you can have

any combination of FC and Ethernet gateways, up to and including 12 Ethernet gateway

models or 12 FC modules.

Figure 2-8 shows the individual Fibre Channel and Ethernet gateway modules. The Fibre

Channel gateway module offers two 1/2G Fibre Channel ports to the SAN network, and two

4X (10 Gbps) InfiniBand ports to the internal InfiniBand fabric. The Ethernet gateway module

offers six 10/100/1000G Ethernet ports to the LAN, and two 4X (10 Gbps) InfiniBand ports to

the internal InfiniBand fabric.
