Abstract

A power-managed server and method for managing power consumption is disclosed. According to one embodiment, a power-managed server data processing system is provided among a plurality of server data processing systems which comprises a power management communication port to communicatively couple the power-managed server data processing system to a power management server data processing system of the plurality of server data processing systems. The power-managed server data processing system of the described embodiment further comprises a system management processor coupled to the power management communication port which comprises power-managed logic configured to transmit power management data to the power management server data processing system and to receive a power management command utilizing the power management communication port. Moreover, the power management command is generated utilizing the power management data, and the power management data comprises power management capability data.

Claims

1. 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:

transmitting power management data from said power-managed server data processing system to said power management server data processing system via a power management communication port;

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

said power management command is generated utilizing said power management data; and

said power management data comprises power management capability data; and

performing a power management operation at said power-managed server data processing system in response to said receiving;

detecting a decoupling of said power-managed server data processing system from said power management server data processing system; and

causing said power-managed server data processing system to assume a predetermined power consumption level in response to said detecting.

2. The method of claim 1, wherein said power-managed server data processing system is associated with 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 command is generated utilizing said static power management priority level and said dynamic power management priority level.

3. The method of claim 1, further comprising:

performing a power management operation in response to said power management command.
