Abstract

An equipment rack load modulation system and method are presented. An equipment rack aggregate thermal and power budget is determined. The aggregate thermal and power budget is allocated based upon rack equipment loaded in an equipment rack. The rack equipment is then operated in accordance with the allocation of the aggregate thermal and power budget.

Claims

1. An equipment rack load modulation method comprising:

determining an equipment rack aggregate thermal and power budget;

allocating said aggregate thermal and power budget based upon rack equipment loaded in said equipment rack; and

operating said rack equipment in accordance with said allocation of said aggregate thermal and power budget.

2. The method of claim 1 further comprising making an equipment rack loading inquiry.

3. The method of claim 2 further comprising examining the amount of rack equipment loaded in said equipment rack.

4. The method of claim 1 further comprising retrieving rack equipment description information.

5. The method of claim 4 further comprising retrieving information on heat dissipation characteristics of said rack equipment.

6. The method of claim 4 wherein said equipment rack aggregate thermal and power budget is based upon heat dissipation provided by passive cooling characteristics of said equipment rack, heat dissipation provided by active cooling features of said equipment rack, and heat dissipation assistance provided by external cooling support.

7. The method of claim 1 wherein said operating said rack equipment includes issuing commands directing said rack equipment operation in accordance with said budget allocation.

8. A computer-useable storage medium comprising computer-readable program code embodied therein for causing a computer system to implement thermal and power budget allocation instructions, comprising:

a thermal and power budget estimating module for estimating a thermal and power budget for an equipment rack;

a thermal and power budget allotment module for allotting said thermal and power budget to rack equipment in said equipment rack; and

a control module for generating rack equipment control commands for controlling said rack equipment in accordance with said thermal and power budget allotment.

9. The computer-useable medium of claim 8 wherein said control module generates commands for altering power consumption and thermal load of said rack equipment.

10. The computer-useable medium of claim 8 further comprising a thermal and power budget event spawning module for generating thermal and power budgeting events for said equipment rack.

11. The computer-useable medium of claim 8 further comprising a telemetry monitoring module for monitoring operations of said rack equipment.

12. The computer-useable medium of claim 8 wherein said thermal and power budget estimating module evaluates said equipment rack load.

13. The computer-useable medium of claim 8 wherein said control commands control a performance level of said rack equipment.

14. An equipment rack load modulation system comprising:

rack equipment for processing data;

a loading budget implementation component for modulating said rack equipment operation based upon loading of an equipment rack; and

a communications bus for communicatively coupling said rack equipment and said budget allocation component, wherein said communications bus communicates data between said thermal and power budget allocation component and said rack equipment.

15. The system of claim 14 wherein said loading budget implementation component modulates a performance frequency and a voltage of said rack equipment.

16. The system of claim 14 wherein said loading budget implementation component modulates operation of said rack equipment by switching on and off said rack equipment.

17. The system of claim 14 wherein said loading budget implementation component dynamically modulates said rack equipment operations interactively.

18. The system of claim 14 wherein said loading budget implementation component modulates said rack equipment operations in accordance with said rack equipment nominal specifications.

19. The system of claim 14 wherein said loading budget implementation component allocates said thermal and power budget proportionally to each piece of said rack equipment contributing to said thermal budget.

20. The system of claim 14 said loading budget implementation component optimally balances said thermal and power budget allocation with a performance level of said rack equipment.
