Multi-Switch Interconnect Module for IBM BladeCenter
IBM BladeCenter at-a-glance guide
The Multi-Switch Interconnect Module (MSIM) for IBM BladeCenter is an innovative solution if you are
looking to use additional standard form-factor switches in place of the high-speed switch bays in the
BladeCenter H chassis. By using redundant MSIMs, you can deploy virtualization-ready solutions by
providing up to eight Ethernet network interface cards (NICs) to each blade server in the chassis.
Figure 1 shows the MSIM.

Did you know?
Two MSIMs can be used in each BladeCenter H chassis, making it ideal for those who are looking for
redundancy. The use of the MSIM to add four additional ports makes it ideal for application such as server
consolidation and virtualization.
Up to two standard form-factor switches can be supported per MSIM, for a total of eight switches in the
BladeCenter H chassis.

The MSIM is a switch module container that converts a stacked pair of high-speed I/O bays into two
standard I/O bays. Figure 2 shows the MSIM being installed into bays 7 and 8 of the BladeCenter H
chassis.

Figure 3 shows how two MSIMs can be installed in the BladeCenter H: one in the space of switch bays 7
and 8, and one in the space of switch bays 9 and 10. The MSIM accepts two supported standard switch
modules and enables a blade server to have up to a total of eight network connections. To connect to the
switch modules in the MSIM, a blade server must have a CFFh-type adapter installed.

Supported expansion cards
To use the MSIM, each blade must have a supported CFFh expansion cards installed. Table 3 lists the
supported CFFh cards.
