Multi-Switch Interconnect Module for IBM BladeCenter

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.

Features

MSIM has the following features:

• Provides standard I/O module support in the high-speed switch bays of BladeCenter H
• Accommodates two standard I/O modules (Ethernet Switch Modules, Fibre Channel Switch
• Modules, or Pass-thru Modules), side by side
• Leverages the I/O design of BladeCenter H to provide increased connectivity to each blade

Operating environment

• The expansion card is supported in this environment:
• Temperature: 10° to 35°C (50° to 95°F)

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

Figure 2. MSIM installed in bays 7 and 8 of the BladeCenter H chassis
Figure 3 shows how two MSIMs can be installed in 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.

Figure 3. Two MSIMs installed in the BladeCenter H chassis

Supported expansion cards

To use the MSIM, each blade must have supported CFFh expansion cards installed. Table 3 lists the supported CFFh cards. Table 3. Expansion cards that can be used to connect to I/O modules in an MSIM

Supported
QLogic Ethernet and 8Gb Fibre Channel Expansion Card  CFFh)| 44X1940| Supported
4X InfiniBand DDR Expansion Card| 43W4423| No
Voltaire 4X InfiniBand DDR Expansion Card| 43W4420| No
QLogic 2-port 10Gb Converged Network Adapter (CFFh)| 42C1830| No
Emulex Virtual Fabric Adapter (CFFh)| 49Y4235| No

The ports on the CFFh expansion cards in each server are hard-wired to specific bays in the switch modules in each MSIM. Table 4 lists the mapping of expansion card ports to the I/O bays of MSIMs.
Table 4. Mapping of expansion card ports to the I/O bays of MSIMs

Port number of the CFFh expansion card| Corresponding switch module bay in the MSIM
---|---
1| 7 (upper left interconnect module bay)
2| 8 (upper right interconnect module bay)
3| 9 (lower left interconnect module bay)
4| 10 (lower right interconnect module bay)

Supported I/O modules
Table 5 lists the supported standard form factor I/O modules and the MSIM bays in which they are supported. For each of the expansion cards that support the MSIM (see Table 3), the MSIM supports I/O modules in the left bay, the right bay, or both bays of the MSIM. Table 5 summarizes this support. Because the supported expansion cards are Ethernet or Fibre Channel only, no SAS or InfiniBand switch modules are supported in the MSIM.
Note the following explanation when viewing the table:

• Right means that the module is only supported in the rightmost I/O slot of the MSIM.
• Left means that the module is only supported in the leftmost I/O slot of the MSIM.
• Both means that the module is supported in both the rightmost and leftmost I/O slots.
• No means that the module is either not supported or not recommended for performance reasons (foexample, mixing a 4 Gb FC with an 8 Gb FC).

Notes:

1. When this 4Gb I/O module is used with the QLogic Ethernet and 8Gb Fibre Channel Expansion Card (CFFh), the card operates only at 4 Gbps.
2. When this 8Gb I/O module is used with the QLogic Ethernet and 4Gb Fibre Channel Expansion Card (CFFh), the module operates only at 4 Gbps.
3. When the Optical Pass-thru Module is installed in the right-hand MSIM bay (for use with a Fibre Channel expansion card), the Optical Pass-thru Module only operates at 2 Gbps. This is a limitation of the OPM.

Popular configurations
This section illustrates how the MSIM can be used in BladeCenter H configurations to add four extra ports to each server in the chassis.
Eight Ethernet ports per server
With the MSIM, it is possible to supply eight Ethernet ports to every BladeCenter server installed in the BladeCenter H chassis, as shown in Figure 4. In this configuration, each BladeCenter server has both a 2/4 Port Ethernet Expansion Card (CFFh) expansion card plus an Ethernet expansion card (CFFv or CIOv form factor, depending on the model of the server). Eight Ethernet switch modules are installed in the BladeCenter H chassis, four of them in MSMEs. All connections between the cards and the switch modules are internal to the chassis. No extra cabling is needed.
