Power Supply Engagement and Method Therefor Data

摘要

A system includes power supply units (PSUs) to supply power to components. For each PSU, a power conversion efficiency profile is determined. A maximum amount of power consumed during operation of the components is determined. A minimum number of PSUs capable of providing the maximum amount of power is determined. A first amount of power consumed at inputs of the minimum number of PSUs is calculated based on the maximum amount of power and based on the determined power conversion efficiency profile of each of the PSUs. A first number of PSUs to engage is determined, the first number greater than the minimum number of PSUs, wherein a total amount of power consumed at inputs of the first number of PSUs during operation of the system is less than the first amount of power, the determining based on the power conversion efficiency profile of each PSU.

主权项

1. In an information handling system comprising a plurality of power supply units (PSUs) to supply power to one or more components of the information handling system, a method comprising:
determining, for each PSU, a power conversion efficiency profile representing a power conversion efficiency of the PSU for each of a predetermined number of PSU output load values; determining a maximum amount of power consumed during operation of the one or more components; determining a minimum number of PSUs capable of providing the maximum amount of power, calculating a first amount of power consumed at inputs of the minimum number of PSUs based on the maximum amount of power and based on the power conversion efficiency profile of each of the PSUs; and determining a first number of PSUs to engage to provide power to the one or more components, the first number greater than the minimum number of PSUs, wherein a total amount of power consumed at inputs of the first number of PSUs during operation of the information handling system is less than the first amount of power, the determining based on the power conversion efficiency profile of each PSU.
