The Dell Chassis Management Controller (CMC) is a systems management component designed to manage one or more Dell PowerEdge Modular Infrastructures containing blade servers – PowerEdge M1000e, VRTX and FX series servers. Unlike a tower or rack server, a blade server cannot run by itself; it requires a compatible blade chassis. Blade servers are typically optimized to minimize the use of physical space and energy while still providing ample computing power.
The blade enclosure, which can hold multiple blade servers, provides power, cooling, networking, various interconnects and additional systems management capabilities. The term “blade” or “blades” is largely interchangeable with the term “server node” and “sled” when referring to the Dell PowerEdge M1000e, VRTX and FX platforms, though the blades themselves may or may not be interchangeable between the different types of modular enclosures. Refer to the SLN294897 for additional information.
The CMC is a hot-pluggable module within a Dell blade enclosure, has its own microprocessor and memory, and is powered by the modular enclosure into which it is plugged - like the M1000e, VRTX and FX, regardless of enclosure. It provides a secure browser-based interface that enables an IT administrator to take inventory, perform configuration and monitoring tasks, remotely power on/off blade servers and enable alerts for events on servers and components in the blade enclosure. This ability is embedded into the module and requires no additional software installations.
One of the features of the CMC is multi-chassis management. This capability can monitor up to 9 fully loaded M1000e chassis, 9 fully loaded VRTX chassis or 20 FX series chassis with no additional cabling via a single web interface.
The CMC interface integrates with the iDRAC module from each blade or server node, so that administrators can perform server-specific iDRAC functions such as performing updates, changing settings, or opening a remote console session from the CMC interface.
Additionally, CMC allows you to back up and replicate settings on the chassis, and save or apply BIOS profiles for individual blade servers so that adding new blades or chassis to your environment is easier and more automated. With newer versions of CMC, it is even possible to assign settings to an empty slot, so that the settings will be applied when a blade is inserted at some point in the future.
You can also capture a complete Chassis Inventory across all of your chassis that will return detailed information on all of the blades, IO modules, iDRAC cards, etc. in your environment.
