IBM IBM Flex System Chassis Management Module

The Chassis Management Module (CMM) provides single-chassis management. The CMM is used to communicate with the management controller in each compute node (IMMv2 in Intel processor-based compute nodes and FSP in POWER7® processor-based compute nodes) to provide system monitoring, event recording and alerts, and to manage the chassis, its devices, and the compute nodes.

The chassis supports up to two CMMs. If one CMM fails, the second CMM can detect its inactivity and activate itself to take control of the system without any disruption. The CMM is central to the management of the chassis and is required in the Enterprise Chassis.
