Power consumption monitor and method therefor

摘要

A power supply unit of an information handling system determines that a power consumption module of the information handling system is available. If the power consumption module is available, the power supply unit measures input power of the power supply unit and provides a representation of the input power to the power consumption module in response to receiving a power measurement request from the power consumption module. If the power supply unit determines that the power consumption module is not available, the power supply unit measures input power of the power supply unit and stores a representation of the input power at the power supply unit independent of a power measurement request from the power consumption module.

1. A method comprising:
operating a power supply unit (PSU) of one or more computer systems in a first mode while the PSU determines that a power consumption module for the one or more computer systems is available, whereby in the first mode the PSU measures a first input power of the PSU and provides a representation of the first input power to the power consumption module, wherein both the measuring and the providing are in response to receiving a power measurement request from the power consumption module, and wherein the measuring comprises measuring a power consumption at a time of measurement; and operating the PSU in a second mode while the PSU determines that the power consumption module is unavailable, whereby in the second mode the PSU measures a second input power of the PSU and stores a representation of the second input power at the PSU, wherein both the measuring and the providing are independent of a power measurement request from the power consumption module.
