Abstract

A method for minimizing power consumption in a computer server is provided. Collected data for an event is compared with an entry in a power consumption table. A power reduction mechanism is triggered if the collected data and the entry are within a specified range. The power consumption table is updated with the collected data if the collected data and the entry are not within the specified range.

Claims

1. A method for minimizing power consumption in a computer server, comprising:

comparing collected data for an event with an entry in a power consumption table;

triggering a power reduction mechanism if the collected data and the entry are within a specified range; and

updating the power consumption table with the collected data if the collected data and the entry are not within the specified range.

2. The method of claim 1, further including determining if the entry is found in the power consumption table.

3. The method of claim 2, further including adding the event as an entry in the power consumption table if the entry is not found in the power consumption table.

4. The method of claim 1, further including continuing to execute the power reduction mechanism for a specified duration time stored in the power consumption table.

5. The method of claim 3, wherein adding the event as a new entry in the power consumption table includes adding a start time, an end time, a usage percentage, or a duration.

6. The method of claim 1, wherein triggering the power reduction mechanism includes adjusting the collective power consumption of a plurality of computer servers.

7. The method of claim 6, wherein adjusting the collective power consumption of the plurality of computer servers includes powering down or reducing a processing speed of at least one of the plurality of computer servers.

8. A system for minimizing power consumption in a computer server, comprising:

a controller operable on the computer server, the controller configured to;

compare collected data for an event with an entry in a power consumption table,

trigger a power reduction mechanism if the collected data and the entry are within a specified range, and

update the power consumption table with the collected data if the collected data and the entry are not within the specified range.

9. The system of claim 8, wherein the controller is further configured to determine if the entry is found in the power consumption table.

10. The system of claim 9, wherein the controller is further configured to add the event as an entry in the power consumption table if the entry is not found in the power consumption table.

11. The system of claim 8, wherein the controller is further configured to execute the power reduction mechanism for a specified duration time stored in the power consumption table.

12. The system of claim 10, wherein the event is a start time, an end time, a usage percentage, or a duration time.

13. The system of claim 8, wherein the controller is further configured to adjust the collective power consumption of a plurality of computer servers pursuant to the power reduction mechanism.

14. The system of claim 13, wherein the power reduction mechanism powers down or reduces a processing speed of at least one of the plurality of computer servers to adjust the collective power consumption.

15. A computer program product for minimizing power consumption in a computer server, the computer program product comprising a computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:

a first executable portion for comparing collected data for an event with an entry in a power consumption table;

a second executable portion for triggering a power reduction mechanism if the collected data and the entry are within a specified range; and

a third executable portion for updating the power consumption table with the collected data if the collected data and the entry are not within the specified range.

16. The computer program product of claim 15, further including a fourth executable portion for determining if the entry is found in the power consumption table.

17. The computer program product of claim 16, further including a fifth executable portion for adding the event as an entry in the power consumption table if the entry is not found in the power consumption table.

18. The computer program product of claim 15, further including a fourth executable portion for continuing to execute the power reduction mechanism for a specified duration time stored in the power consumption table.

19. The computer program product of claim 15, wherein the event is a start time, an end time, a usage percentage, or a duration.

20. The computer program product of claim 15, wherein the power reduction mechanism adjusts the collective power consumption of a plurality of computer servers.

21. The computer program product of claim 20, wherein the power reduction mechanism adjusts the collective power consumption of the plurality of computer servers by powering down or reducing a processing speed of at least one of the plurality of computer servers.
