When a chassis is powered on, the Chassis Monitoring Module (CMM) allocates power to chassis components and Server Modules (blades) using power management metrics. The CMM automatically partitions the amount of Total Power available to components and blades between the chassis Available Power and Reserve Power. This power partitioning is based on the number of energized power supply modules and any previous power partitioning settings. However, you can adjust the power partitioning settings at any time to increase the amount of Available Power or Reserve Power.
You should adjust the power partitioning settings when there is not enough Available Power to accommodate the power requirements of a chassis component or blade. You should increase the amount of Reserve Power when necessary.
