Abstract
When the maximum power consumption of a computer exceeds a currently selected power-consumption cap, a cap setting corresponding to the currently selected power-consumption cap is reduced. In addition, power-cap settings corresponding to power-consumption caps between said currently selected power-consumption cap and said maximum power consumption are reduced.
Claims15
A method comprising:
- selecting a first power-consumption cap as the currently selected power-consumption cap from a series of power-consumption caps;
- configuring a computer according to a power-cap setting associated with said currently selected power-consumption cap;
- and
- in the event a maximum power consumption of said computer exceeds said currently selected power-consumption cap, decrementing the power-cap setting corresponding to the currently selected power-consumption cap and decreasing power-cap settings corresponding to power caps between the currently selected power cap setting and said maximum power consumption.

A system comprising;
- a power controller that provides for selecting a first power-consumption cap as the currently selected power-consumption cap, said first power-consumption cap being selected from a series of power-consumption caps, said power controller providing, for each of said target power consumption caps, a respective power-cap setting for each of said power-consumption caps that is used to configure a computer;
- and
- a cap analyzer configured to determine from received power-consumption data when a maximum power consumption by said computer exceeds a currently-set power consumption cap, and to, in the event said maximum power consumption by said computer exceeds said currently set power-consumption cap, reduce power cap settings for said currently set power consumption cap and for other power-consumption caps exceeded by said maximum power consumption.
A computer product comprising non-transitory computer-readable storage media encoded with code providing for:
- selecting a currently selected power-consumption cap from a series of power-consumption caps;
- configuring a computer according to a power-cap setting associated with said currently selected power consumption cap so that said computer's expected maximum power consumption does not exceed said currently selected power-consumption cap;
- and
- in the event a maximum power consumption of said computer exceeds said currently selected power consumption cap, reducing cap settings for a range of currently selected power consumption caps, said range including said currently selected power-consumption cap and other power-consumption caps greater than said currently selected power consumption cap and less than said maximum power consumption.
