Power consumption monitor and method therefor
First Claim
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.

Abstract
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.

11. A system comprising:
-
one or more computer systems; and a power supply unit (PSU) to supply power to one or more components of the system, the PSU comprising; an interface to receive power measurement requests from a power consumption module of the system; a local storage; and a power measurement module to; operate in a first mode while the power measurement module determines that the power consumption module is available, whereby in the first mode the power measurement module 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 power consumption at a time of measurement; and operate in a second mode while the power measurement module determines that the power consumption module is unavailable, whereby in the second mode the power measurement module measures a second input power of the PSU and stores a representation of the second input power at the local storage independent of a power measurement request from the power consumption module. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. In an information handling system, a method comprising:
-
providing power from a power supply unit (PSU) exclusively to at least one component of the information handling system; determining, at the PSU, a first amount of power received at the input of the PSU and providing a representation of the first amount of power from the PSU to a power consumption module of the information handling system as first power information in response to receiving a first power measurement request from the power consumption module; in response to determining at the PSU that a power measurement request has not been received within a predetermined amount of time; periodically determining an amount of power received at the input of the PSU and storing a representation of the amount of power and a representation of the time at which the amount of power was determined as second power information at a local storage of the PSU; in response to receiving at the PSU a power measurement request from the power consumption module, providing an alert from the PSU to the power consumption module; and providing the representation of the second power information stored at the PSU to the power consumption module in response to receiving at the PSU a status request from the power consumption module, wherein the status request inquires as to the reason for the alert.
