I/O architecture

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.
