The BladeCenter H chassis provides connection paths between the server blade bays and I/O bays through a hardwired dual redundant midplane.

The BladeCenter H chassis has two types of fabrics inside:

• Standard fabric (I/O bays 1, 2, 3, and 4)
• High-speed fabric (I/O bays 7, 8, 9, and 10)

The BladeCenter H chassis has a total of 10 I/O bays. Each blade bay has a total of eight dedicated connection paths to the I/O modules, as shown in the following figure.

Figure 4. BladeCenter H I/O topology

The bays are:

• Bays 1 and 2 support only standard Ethernet-compatible I/O modules. These bays are routed internally to the onboard Ethernet controllers on the blades.
• Bays 3 and 4 can be used either for standard switch or pass-through modules (such as 8 Gb Fibre Channel or Gigabit Ethernet modules) or for bridge modules. These bays are routed internally to the CIOv connector on the blades.
• Bays 5 and 6 are dedicated for bridge modules only and do not directly connect to the blade bays. Bridge modules provide links to the I/O bays 7 - 10 and can be used as additional outputs for I/O modules in those bays. If I/O bays 3 and 4 are used for bridge modules, they are not directly connected to the blades, and bay 3 provides redundancy for bay 5, and bay 4 provides redundancy for bay 6.
• I/O bays 7 - 10 are used for high-speed switch modules such as the Virtual Fabric 10 Gb Switch Module or Cisco Nexus 4001I Switch Module. These bays are routed internally through midplane connectors to the ports on CFFh expansion cards (with HS23 blade, I/O bays 7 and 9 are routed to the integrated 10GbE ports on HS23 through LOM Interposer Card). I/O bays 7 - 10 can also be converted to the standard I/O bays with the Multi-Switch Interconnect Module (MSIM).

The I/O modules must be compatible with the I/O interfaces that are present in the blade servers. For example, when a Fibre Channel expansion card is installed in a blade server, I/O modules 3 and 4 must also be Fibre Channel-based (that is, an FC switch module), and vice versa. If you install FC switches in bays 3 and 4, then any expansion cards that are installed in all other blade servers in the same chassis must be Fibre Channel.

Table 4 shows the connections between the adapter slots in the compute nodes to the switch bays in the chassis.

Table 4. Adapter to I/O bay correspondence

Tables 5 through 7 list the I/O modules that are supported by the BladeCenter H chassis and the corresponding I/O bay into which the I/O module can be installed.
