The Chassis Management Module (CMM) provides single-chassis management in the Enterprise Chassis. The CMM is used to communicate with the integrated management module (IMM) controller in each compute node to provide system monitoring, event recording and alerts, and to manage the chassis, its devices, and the compute nodes.
The chassis has one CMM installed standard but supports two CMMs for redundancy. 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.
