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 power-managed server data processing system among a plurality of server data processing systems, said power-managed server data processing system comprising:

a power management communication port to communicatively couple said power-managed server data processing system to a power management server data processing system of said plurality of server data processing systems;

a system management processor coupled to said power management communication port comprising;

power-managed logic configured to transmit power management data to said power management server data processing system and to receive a power management command 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;

wherein said power-managed logic is further configured to detect a decoupling of said power-managed server data processing system from said power management server data processing system and to assume a predetermined power consumption level in response to said decoupling.

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

said power-managed server data processing system and said plurality of server data processing systems compose a rack server;

and

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

4. The power-managed server data processing system of claim 1, wherein said power-managed logic is further configured to perform a power management operation in response to said power management command.
