IBM Flex System Chassis Management Module (CMM)
CMM is the default integrated platform for managing a single IBM Flex System Enterprise
Chassis. It occupies one of the two chassis management bays on the rear of the chassis.
A second module can be installed for redundancy.
More information regarding IBM Flex System Chassis Management Module can be found at
3.2.1, “Overview of IBM Flex System Chassis Management Module” on page 90.
I/O modules (switch modules)
I/O modules contain the internal management interfaces and Inter-Integrated Circuit (I2C) for
management. They can be managed by the IBM Flex System Manager, IBM Flex System
Chassis Management Module, command line interface (CLI), web interface, IBM System
Network Element Manager (SNEM), or any third-party SNMP-based management tool.
Compute node management processors
There are two types of compute nodes in an IBM Flex System:
For IBM x86 (intel-based) compute nodes, the management interface is IMMv2, which is a
powerful management interface providing control at node-level.
For POWER compute nodes, the Flexible Service Processor (FSP) provides a
serial-over-LAN (SOL) interface for performing common management tasks on the node.
Table 3-1 gives an overview of system management capabilities of these hardware
management devices.
