Abstract
A demand based power re-allocation system includes one or more subsystems to assign a power allocation level to a plurality of servers, wherein the power allocation level is assigned by priority of the server. The system may throttle power for one or more of the plurality of servers approaching the power allocation level, wherein throttling includes limiting performance of a processor, track server power throttling for the plurality of servers. The method compares power throttling for a first server with power throttling for remaining servers in the plurality of servers and adjusts throttling of the plurality of servers, wherein throttled servers receive excess power from unthrottled servers.
Claims20
A power allocation system, comprising:
- a plurality of information handling systems (IHSs) including a high priority IHS and a low priority IHS, wherein the high priority IHS has a higher priority than the low priority IHS;
- and
- a power allocation controller coupled to each of the plurality of IHSs, wherein the power allocation controller is operable to:
- determine that the high priority IHS is being throttled;
- determine that at least one of the plurality of IHSs is not being throttled and, in response, reclaim power from the at least one of the plurality of IHSs that is not being throttled;
- and
- allocate the reclaimed power to the high priority IHS.
A power allocation system, comprising:
- a first subset of a plurality of IHSs;
- a second subset of the plurality of IHSs, wherein the first subset of the plurality of IHSs have higher priorities than the second subset of the plurality of IHSs;
- and
- a power allocation controller coupled to each of the plurality of IHSs, wherein the power allocation controller is operable to:
- determine that the first subset of the plurality of IHSs are being throttled;
- determine that at least one of the plurality of IHSs is not being throttled and, in response, reclaim power from the at least one of the plurality of IHSs that is not being throttled;
- and
- allocate the reclaimed power to the first subset of the plurality of IHSs.
A method for re-allocation power, comprising:
- determining, by a power allocation controller that is coupled to a plurality of IHSs, that a high priority IHS of the plurality of IHSs is being throttled;
- determining, by the power allocation controller, that at least one of the plurality of IHSs is not being throttled and, in response, reclaiming power from the at least one of the plurality of IHSs that is not being throttled;
- and
- allocating, by the power allocation controller, the reclaimed power to the high priority IHS.
