Abstract

A power management server and method for managing power consumption is disclosed. According to one embodiment, a power management server data processing system is provided, where the power management server data processing system comprises a power management communication port to communicatively couple the power management server data processing system to a power-managed server data processing system and a system management processor coupled to the power management communication port. In the described embodiment, the system management processor comprises power management logic configured to receive power management data from the power-managed server data processing system, to generate a power management command utilizing the power management data, and to transmit the power management command to the power-managed server data processing system utilizing the power management communication port. Moreover, the power management data of the described embodiment comprises power management capability data.

said power management data comprises power management capability data.

2. The power management server data processing system of claim 1, wherein

said power management server data processing system further comprises a storage element to store data specifying a static power management priority level associated with said power-managed server data processing system,

said power management data comprises data specifying a dynamic power management priority level associated with said power-managed server data processing system, and

said power management logic is further configured to generate said power management command utilizing said static power management priority level and said dynamic power management priority level.

3. The power management server data processing system of claim 1, wherein

said power management data comprises first power management data,

said power management command comprises a first power management command,

said system management processor further comprises power-managed logic configured to transmit second power management data associated with said power management server data processing system to said power management logic, to receive a second power management command from said power management logic, and to perform a power management operation in response to a receipt of said second power management command, and

said power management logic is further configured to receive said second power management data, to generate said second power management command, and to transmit said second power management command to said power-managed logic.

4. The power management server data processing system of claim 1, wherein

said plurality of server data processing systems comprises a non-power-managed server data processing system, and

said power management logic is further configured to determine an effective power consumption level of said non-power-managed server data processing system and to generate said power management command utilizing said effective power consumption level.

5. The power management server data processing system of claim 1, wherein

said power-managed server data processing system comprises a first power-managed server data processing system,

said power management logic is further configured to detect a decoupling of said power management server data processing system from a second power-managed server data processing system, to determine an effective power consumption level of said second power-managed in response to said decoupling, and to generate said power management command utilizing said effective power consumption level.

6. The power management server data processing system of claim 1, wherein

said power management server data processing system and said plurality of server data processing systems compose a rack server, and

each of said power management server data processing system and said plurality of server data processing systems is coupled to a common power input.

7. A method of managing power consumption of a plurality of server data processing systems, wherein said plurality of server data processing systems comprises a power management server data processing system and a power-managed server data processing system, said method comprising:

receiving power management data from said power-managed server data processing system at said power management server data processing system via a power management communication port;

generating a power management command utilizing said power management data at said power management server data processing system; and

transmitting said power management command from said power management server data processing system to said power-managed server data processing system utilizing said power management communication port, wherein

said power management data comprises power management capability data.

8. The method of claim 7, further comprising:

causing data specifying a static power management priority level associated with said power-managed server data processing system to be stored within a storage element of said power management server data processing system, wherein

said power management data comprises data specifying a dynamic power management priority level associated with said power-managed server data processing system, and

generating said power management command utilizing said static power management priority level and said dynamic power management priority level.

9. The method of claim 7, wherein

said plurality of server data processing systems comprises a non-power-managed server data processing system, and

said method further comprises

determining an effective power consumption level of said non-power-managed server data processing system, and

generating said power management command utilizing said effective power consumption level.

10. The method of claim 7, wherein

said power-managed server data processing system comprises a first power-managed server data processing system,

said method further comprises

detecting a decoupling of said power management server data processing system from a second power-managed server data processing system of said plurality of server data processing systems,

determining an effective power consumption level of said second power-managed in response to said detecting, and

generating said power management command utilizing said effective power consumption level.

11. A machine-readable medium having a plurality of instructions executable by a machine embodied therein, wherein said plurality of instructions when executed cause said machine to perform a method for managing power consumption of a plurality of server data processing systems, wherein said plurality of server data processing systems comprises a power management server data processing system and a power-managed server data processing system, said method comprising:

receiving power management data from said power-managed server data processing system at said power management server data processing system via a power management communication port;

generating a power management command utilizing said power management data at said power management server data processing system; and

transmitting said power management command from said power management server data processing system to said power-managed server data processing system utilizing said power management communication port, wherein

said power management data comprises power management capability data.

12. The machine-readable medium of claim 11, said method further comprising:

causing data specifying a static power management priority level associated with said power-managed server data processing system to be stored within a storage element of said power management server data processing system, wherein

said power management data comprises data specifying a dynamic power management priority level associated with said power-managed server data processing system, and
