Power consumption monitor and method therefor
First Claim
1. In a server rack, a method comprising:
- operating a power supply unit (PSU), the PSU to provide power exclusively to the server rack, in a first mode while the PSU determines that a power consumption module of a chassis management control module of the server rack 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 in response to receiving a power measurement request from the power consumption module, wherein the chassis management control module is configured to activate and deactivate server nodes of the server rack in response to a power conservation policy; 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 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.

10. A server rack comprising:
-
a power supply unit (PSU) to supply power exclusively to one or more components of the server rack, the PSU comprising; an interface to receive power measurement requests from a power consumption module of the server rack; 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 operating 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, wherein both the measuring and the storing are independent of a power measurement request from the power consumption module. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. 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 indication from the PSU to the power consumption module that the PSU has stored a representation of the second power information; 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 request for the representation of the second power information from the power consumption module, wherein the request for the representation is a separate request from the power measurement request. - View Dependent Claims (19, 20)
