Abstract
An information handling system includes a power supply unit, a processor, and a baseboard management controller. The power supply unit includes a first energy counter configured to store first power level information associated with an amount of power supplied by the power supply unit. The processor includes a second energy counter configured to store second power level information associated with an amount of power consumed by the processor. The baseboard management controller periodically calibrates the second power level to the first power level based upon a variable calibration cycle time.
Claims20
An information handling system, comprising:
- a power supply unit including a first energy counter that indicates first power level information associated with an amount of power supplied by the power supply unit;
- a processor including a second energy counter that indicates second power level information associated with an amount of power consumed by the processor;
- and
- a baseboard management controller configured periodically calibrate the second power level to the first power level based upon a variable calibration cycle time.
A method, comprising:
- providing, in a power supply unit of an information handling system, a first energy counter that indicates first power level information associated with an amount of power supplied by the power supply unit;
- providing a second energy counter that indicates second power level information associated with an amount of power consumed by a processor;
- and
- periodically calibrating, by a baseboard management controller of the information handling system, the second power level to the first power level based upon a variable calibration cycle time.
An information handling system, comprising:
- a power supply unit including a first energy counter configured to store first power level information associated with an amount of power supplied by the power supply unit;
- a processor including a second energy counter configured to store second power level information associated with an amount of power consumed by the processor;
- a voltage regulator configured to receive power from the power supply, and to provide a regulated voltage to the processor;
- and
- a baseboard management controller configured periodically calibrate the second power level to the first power level based upon a variable calibration cycle time, wherein in calibrating the second power level, the baseboard management controller is further configured to change a conversion factor of the voltage regulator.
