发明名称 Power supply engagement and method therefor
摘要 An information handling system includes a plurality of power supply units (PSUs) to supply power to one or more system components. For each PSU of the plurality of PSUs, a power conversion efficiency profile for the PSU is determined using a power management control module of the information handling system. The power conversion efficiency profile represents a power conversion efficiency of the PSU for each of one or more power outputs capable of being supplied by the PSU. The power management control module determines a total amount of power to be supplied to a load of the information handling system, and engages a select number of PSUs to provide the total amount of power based on the total amount of power and the power conversion efficiency profiles of the PSUs.

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 for the PSU using a power management control module of the information handling system, the power conversion efficiency profile representing a power conversion efficiency of the PSU for each of one or more power outputs of the PSU; 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; determining, based on a PSU redundancy policy of the information handling system, a first number of PSUs greater than the minimum number of PSUs, the policy specifying a number of additional PSUs to engage so that if one or more PSUs fails during operation, a remaining number of functional PSUs is capable of supplying the maximum amount of power; determining a first amount of power consumed at inputs of the first number of PSUs during operation of the one or more components; and determining a second number of PSUs to engage to provide power to the one or more components, the second number greater than the first number of PSUs, wherein a total amount of power consumed at inputs of the second 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.
