A method of adjusting power budgets of multiple servers within a data center comprises various actions. Such actions include, for example, organizing the multiple servers into hierarchical groups, dividing a total power budget among the hierarchical groups, and assigning power consumption levels to individual members of a particular hierarchical group such that the sum total of the assigned power consumption levels does not exceed the total power budget for the particular hierarchical group. The act of dividing is dynamic with respect to time.

What is claimed is: 1. A computer implemented method of adjusting power budgets of multiple servers within a data center, comprising: organizing the multiple servers into hierarchical groups; dividing a total power budget among the hierarchical groups; and assigning power consumption levels to individual members of a particular hierarchical group such that the sum total of the assigned power consumption levels does not exceed the total power budget for the particular hierarchical group; wherein the act of dividing is dynamic with respect to time. 2. The computer implemented method of claim 1, further comprising at least one of the individual members of the particular hierarchical group requesting a greater power consumption level. 3. The computer implemented method of claim 1, further comprising periodically allowing one of the individual members of the particular hierarchical group to consume the total power budget for the particular hierarchical group. 4. The computer implemented method of claim 3, wherein the act of periodically allowing one of the individual members to consume the total power budget for the particular hierarchical group occurs according to a priority scheme. 5. The computer implemented method of claim 1, wherein the method is performed recursively at each level within the data center. 6. The computer implemented method of claim 1, further comprising negotiating a new power rating for a server within the multiple servers, wherein the negotiation occurs between a first management device located within the server and a second management device located higher up in the hierarchical orientation than the server. 7. The computer implemented method of claim 2, further comprising prioritizing, with a group manager, the order in which the multiple servers within the data center contribute power to the total power budget for the data center. 8. The computer implemented method of claim 2, further comprising prioritizing, with a group manager, the order in which the multiple servers within the data center acquire power from the total power budget for the data center. 9. The computer implemented method of claim 6, further comprising staging a power on of the multiple servers such that subsequent servers do not begin negotiating until previously powered on servers have reached a stable power consumption state. 10. The computer implemented method of claim 6, wherein the act of negotiating is based on a prior history of power negotiation. 11. A data center with adjusted power budgets, comprising: a plurality of servers within the data center, wherein the plurality of servers are hierarchically organized into groups and each hierarchical group further comprises a first management processor; and a second management processor that divides a total power budget for the data center among the hierarchical groups within the plurality of servers and communicates with the first management processor to assign a power consumption level to each server within a particular hierarchical group; wherein the sum total of the assigned power consumption levels does not exceed the total power budget for that hierarchical group; wherein the second processor divides the total power budget dynamically with respect to time. 12. The data center of claim 11, wherein at least one of the individual servers of the particular hierarchical group requests a greater power consumption level. 13. The data center of claim 11, wherein one of the servers within the particular hierarchical group is periodically allowed to consume the entire amount of power allocated to the particular hierarchical group. 14. The method of claim 13, wherein individual servers within the particular hierarchical group are each allowed to consume the entire amount of power assigned according to a priority scheme. 15. The method of claim 11, wherein power is divided and assigned recursively at each hierarchical level within the data center. 16. The data center of claim 11, wherein the first and second management processors negotiate a new power rating for at least one server of the plurality of servers. 17. The data center of claim 11, wherein at least one of the servers within the plurality of servers contributes a portion of the power that it was assigned back to other servers within the data center. 18. The data center of claim 11, wherein the servers within the plurality of servers are powered on in stages such that subsequent servers do not begin negotiation until previously powered on servers have reached a stable power consumption state.
