Chassis Management Module Key functions: Power control Fan management Chassis and compute node initialization Switch management Diagnostics: chassis, I/O options, and compute nodes Resource discovery and inventory management Resource alerts and monitoring management Chassis and compute node power management Security policy management Role-based access control Support for up to 84 local CMM user accounts Support for up to 32 simultaneous sessions 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 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. 2015 LENOVO. All rights reserved.
