Patent ID: 8276012

Claim:
A method, in a data processing system, for priority-based power capping, the method comprising: identifying, by a power management controller, a set of priorities for a set of partitions of the data processing system; determining, by the power management controller, whether a measured power of the data processing system exceeds a power cap for the data processing system; responsive to the measured power exceeding the power cap, sending, by the power management controller, a set of commands to a set of component actuators to adjust one or more of a set of operation parameters for a set of components associated with the set of partitions using the set of priorities, wherein using the set of priorities to adjust one or more of the set of operation parameters for the set of components associated with the set of partitions identifies an adjustment of power to each component in the set of components associated with the partitions based on an amount commensurate with the priority of each component; and adjusting, by the set of component actuators, the one or more of the set of operational parameters associated with the set of component in order to reduce a power consumption of the data processing system.
