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.

Abstract: A distributed method and system for managing power usage among server data processing systems are disclosed. According to one embodiment, a server data processing system of a plurality of server data processing systems is provided, where the server data processing system comprises a power management communication port to communicatively couple the server data processing system to all other server data processing systems of the plurality of server data processing systems and a system management processor coupled to the power management communication port. In the described embodiment, the system management processor comprises communication logic configured to monitor power usage of all the other server data processing systems of the plurality, and power management logic configured to perform a power management operation on the server data processing system based upon the monitored power usage.

Abstract: A system and method for managing power usage of a data processing system subsystem are disclosed. According to one embodiment, a power-managed server data processing system is provided which comprises a bus configured to communicatively couple the power-managed server with a data processing system resource; and a bus controller coupled to the bus. In the described embodiment, the bus controller comprises bus control logic configured to process a plurality of access requests associated with the bus, and power management logic configured to inhibit processing of a current access request of the plurality by the bus control logic for a power management delay time period. The power management delay time period is determined utilizing a processing latency time period associated with a prior access request of the plurality of access requests.

Abstract: A hierarchical system and method for managing power usage among server data processing systems is disclosed. According to one embodiment, a hierarchical power management system is provided which comprises first and second power management controllers, a power management command combination element, a power management command terminator, a power-managed data processing system element, and a power management bus coupled between the power management controllers, power management command combination element, and power management command terminator.
