Managing Fabrics

The chassis supports a fabric type, which is Fabric A. Fabric A is used by the single I/O Module, and is always connected to the on-board Ethernet adapters of the servers.

The chassis has only one I/O module (IOM), where the IOM is a pass-through or switch module. The I/O Module is classified as group A.

Chassis IOM uses a discrete data path called Fabric, and it is named A. The Fabric A supports only Ethernet. Each server IO adapter (Mezzanine Card or LOM) can have either two or four ports depending on the capability. The mezzanine card slots are occupied by PCIe extension cards that are connected to PCIe cards (and not to IO modules). When you deploy the Ethernet, iSCSI, or FibreChannel networks, span their redundant links across banks one and two for maximum availability. The discrete IOM is identified with a fabric identifier.

  • NOTE: In the CMC CLI, the IOM is referred to by the convention, switch.
