Dynamic power balancing among blade servers in a chassis

摘要

Techniques are provided to redistribute and rebalance power to a plurality of blade servers with a chassis unit. At a chassis management controller device in a chassis unit comprising a plurality of blade server devices, policy information is stored for the chassis unit. The policy information comprises power limit information that indicates a power budget for the chassis unit and blade server priority information that indicates priority for access to power for each of the plurality of blade servers in the chassis unit. Power is distributed to the plurality of blade servers based on the blade server priority information for each of the plurality of blade servers and the power limit information for the chassis unit. The actual power consumption of each of the plurality of blade servers is determined and power is redistributed to the plurality of blade servers based on the actual power consumption and the policy information.

1. A method comprising:
at a chassis management controller device in a chassis unit comprising a plurality of blade servers, storing policy information for the chassis unit, wherein the policy information comprises:
blade server priority information that indicates an assignment of each of the blade servers to one of a plurality of blade server priority classes having different priorities, anda power budget for the chassis unit that is based on the blade server priority classes of the plurality of blade servers such that chassis units with more blade servers assigned to higher priority classes are budgeted more power relative to other chassis units with fewer blade servers assigned to higher blade server priority classes; receiving, at the chassis unit, power at a power level substantially equal to the power budget for the chassis unit; at the chassis management controller device, distributing power to the plurality of blade servers based on the blade server priority class for each of the plurality of blade servers and the power budget for the chassis unit; at the chassis management controller device, determining an actual power consumption of each of the plurality of blade servers; and at the chassis management controller device, redistributing power to the plurality of blade servers based on the actual power consumption and the policy information.
