DISTRIBUTED POWER MANAGEMENT WITH PERFORMANCE AND POWER BOUNDARIES

摘要

It is determined that a current node power consumption for a node is greater than a node power cap that defines a limit of power consumption for the node. Responsive to the current node power consumption being greater than the node power cap and until the current node power consumption is less than the node power cap, power reduction operations are performed. The power reduction operations comprise determining a power management zone of a plurality of power management zones having a lowest priority among the power management zones and having a power cap greater than a minimum power cap for the power management zone. The power reduction operations further comprise setting the power cap for the power management zone to a value less than a prior value assigned as the power cap for the power management zone.

1. A method comprising:
determining that a current node power consumption for a node is greater than a node power cap that defines a limit of power consumption for the node, wherein the node comprises a plurality of power management zones, wherein each of the plurality of power management zones has a power cap that defines a limit of power consumption for the power management zone; in response to the current node power consumption being greater than the node power cap and until the current node power consumption is less than the node power cap, performing power reduction operations, wherein the power reduction operations comprise,
determining a power management zone of the plurality of power management zones having a lowest priority among the plurality of power management zones and having a power cap greater than a minimum power cap for the power management zone; andsetting the power cap for the power management zone of the plurality of power management zones to a value less than a prior value assigned as the power cap for the power management zone of the plurality of power management zones.
