Power Management Overview

The Chassis Monitoring Module (CMM) manages the allocation of power to Sun Blade 8000 Series Chassis components and blades using a power "ticketing" protocol process, which is initiated when the Service Processor (SP) boots. The CMM grants a power ticket to a blade if enough non-reserve power exists to satisfy the request. This close management by the CMM prevents involuntary shutdowns of the Sun Blade 8000 Series chassis due to overconsumption of available power.

Note

An involuntary shutdown of the chassis will occur as a result of failed power supplies, improper removal of power, or the addition of blades with ILOM firmware versions before ILOM 1.1.5. These earlier versions of ILOM do not implement the power management protocol.
