ILOM is supported on a variety of Sun server platforms, including rackmounted servers and blade servers. ILOM firmware is preinstalled on the service processor (SP) of your rackmounted server or blade server, or on the Chassis Monitoring Module (CMM), if applicable to your server platform.
ILOM supports two ways to manage a system: using the SP directly or using the CMM, if applicable.
Using the service processor directly – Managing the SPs of rackmounted servers by communicating directly with the SP or blades enables you to manage individual system or blade operations. This approach may be useful in troubleshooting a service processor or controlling access to specific systems or blades if you have a multi-tenant system.
Using the Chassis Monitoring Module – If your system includes a CMM, managing the system from the CMM enables you to set up and manage components throughout the entire system, or to drill down to manage the individual blade server SP.
