Abstract

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.

Claims (45)

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.

2. The method of claim 1 , wherein the predetermined number of PSU output load values is programmable.

3. The method of claim 1 , wherein the plurality of PSUs includes PSUs having different power output capabilities, and determining a minimum number of PSUs comprises selecting a subset of the plurality of PSUs.

4. The method of claim 3 , further comprising selecting the subset based on the power conversion efficiency profile of each PSU.

5. The method of claim 1 , wherein the power conversion efficiency profile of each PSU includes power conversion efficiency information for two or more output terminals of each PSU.

6. The method of claim 1 , wherein determining the minimum number of PSUs comprises determining the minimum number of PSUs further based on a PSU redundancy policy of the information handling system.

7. The method of claim 1 , further comprising:

determining a first output load value at a first time;

determining a first input power of the PSU at the first time; and

determining a first power conversion efficiency of the PSU for the first output load value based on a ratio of the first output load value to the first input power.

8. The method of claim 1 , wherein determining a power conversion efficiency profile for a PSU comprises:

determining a power conversion efficiency of the PSU for each of a plurality of output load values of the PSU; and

for each determined power conversion efficiency, storing a value representative of the power conversion efficiency in a data structure in a storage component, the data structure representing the power conversion efficiency profile of the PSU.

9. The method of claim 1 , wherein determining the power conversion efficiency profile for a PSU comprises accessing the power conversion efficiency profile from a storage component.

10. An information handling system comprising:

a plurality of components;

a plurality of power supply units (PSUs) to supply power to one or more of the components; and

a power management control module to:

determine, 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;

determine a maximum amount of power consumed during operation of the one or more components;

determine a minimum number of PSUs capable of providing the maximum amount of power;

calculate 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 determined power conversion efficiency profile of each of the PSUs; and

determine 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.

11. The information handling system of claim 10 , the predetermined number of PSU output load values is programmable.

12. The information handling system of claim 10 , wherein the plurality of PSUs includes PSUs having different power output capabilities, and determining a minimum number of PSUs comprises selecting a subset of the plurality of PSUs.

13. The information handling system of claim 12 , wherein the power management control module is further to select the subset based on the power conversion efficiency profile of each PSU.

14. The information handling system of claim 10 , wherein the power conversion efficiency profile of each PSU includes power conversion efficiency information for two or more output terminals of each PSU.

15. The information handling system of claim 10 , wherein the power management control module is further to determine the minimum number of PSUs based on a PSU redundancy policy of the information handling system.

16. The information handling system of claim 10 , wherein to determine a power conversion efficiency profile for a PSU, the power management control module is further to:

determine a power conversion efficiency of the PSU for each of a plurality of output load values of the PSU; and

for each determined power conversion efficiency, storing a value representative of the power conversion efficiency in a data structure in a storage component, the data structure representing the power conversion efficiency profile of the PSU.

17. The information handling system of claim 10 , wherein to determine a power conversion efficiency profile for a PSU, the power management control module is further to access the power conversion efficiency profile from a storage component coupled to the power management control module.

18. A non-transitory computer-readable medium storing a software program, the software program comprising a set of instructions to manipulate at least one processor to:

determine, for each PSU, of the plurality of PSUs, a power conversion efficiency profile for the PSU, the power conversion efficiency profile representing a power conversion efficiency of the PSU for each of a predetermined number of PSU output load values;

determine a maximum amount of power consumed during operation of the one or more components;

determine a minimum number of PSUs capable of providing the maximum amount of power,

calculate 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 determined power conversion efficiency profile of each of the plurality of PSUs; and

determine 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.

19. The computer-readable medium of claim 18 , wherein the predetermined number of PSU output load values is programmable.

20. The computer-readable medium of claim 18 , wherein determining the power conversion efficiency profile for a PSU comprises accessing the power conversion efficiency profile from a storage component.
