Ibm Flex System Chassis Management Module (Cmm); Overview Of Ibm Flex System Chassis Management Module - IBM Flex System V7000 Introduction And Implementation Manual

3.2 IBM Flex System Chassis Management Module (CMM)

The IBM Flex System Chassis Management Module (CMM) is a hot-swap module that
configures and manages all installed chassis components. The chassis comes with one IBM
Flex System Chassis Management Module in the CMM bays.
The IBM Flex System Chassis Management Module auto-detects and manages the hardware
of the entire IBM Flex System Enterprise Chassis. It communicates with the management
controller in each node (IMMv2 in intel processor-based computer nodes, FSP in power
Power7 processor-based nodes), along with the management applications of storage node
and I/O modules to provide centralized system monitoring and management.

3.2.1 Overview of IBM Flex System Chassis Management Module

A IBM Flex System Chassis Management Module (CMM) gives control over the IBM Flex
System at the chassis level, simplifying installation and management of your installation.
The CMM is central to the management of the chassis, and is required in the IBM Flex
System Enterprise Chassis. One CMM comes standard with the chassis. There are two CMM
bays in the chassis, giving the user an option to add a second CMM for redundancy.
Through an embedded firmware stack, the CMM implements functions to monitor, control,
and provide external user interfaces to manage all chassis resources. Here are the key
functions of the IBM Flex System Chassis Management Module:
Single-chassis management
Initial setup configuration wizard from http/s interface
Detailed system health status for components, along with suggested recovery actions
Chassis level hardware inventory management
Chassis configuration and validation
System and component status information
Component LEDs states and controls
Event handling and notification
Hardware access states
Fan status and control
Thermal management and monitoring
Power management and control
Switch modules - monitor and control access
Security features and policies
Service data collection and Call Home services
Configuration backup and restore
Firmware updates
Low level service processor resets
Nodes and I/O module configuration and management
Diagnostics
Network management
Chassis and compute node initialization
Tip: The IBM Flex System Enterprise Chassis supports up to 84 local CMM user accounts,
and allows up to 32 simultaneous sessions.
