The Chassis Monitoring Module (CMM) manages the distribution of power throughout the Sun Blade 8000 Series Chassis. The CMM follows these power management rules when distributing power to chassis components and Server Modules (blades):
Allocate power to blades as they boot.
Monitor power usage both throughout the chassis and on a per-blade basis.
The CMM uses four key power management metrics when distributing power throughout the chassis:
Available Power -- This is the total amount of power that is currently available to components and blades. You can view this metric only using the ILOM interfaces for the CMM.
Reserve Power -- This is the total amount of power that is reserved for use by components and blades. You can view this metric only using the ILOM interfaces for the CMM.
Ticketed Power -- This is the amount of power that is reserved for a specific component or blade. You can view this metric using the ILOM interfaces for the CMM or the ILOM interfaces for the SP if you are viewing Blade Ticketed Power.
Consumed Power -- This is the total amount of power consumed by the entire chassis, or by a specific component or blade. You can view this metric using the ILOM interfaces for the CMM or the ILOM interfaces for the SP if you are viewing Blade Ticketed Power.
Perform the following procedures to proactively monitor power status to avoid an involuntary shutdown of the chassis. An involuntary shutdown of the chassis, such as an oversubscription or brownout, can occur when the amount of Consumed Power exceeds the amount of Available Power.
