Abstract
According to the present invention, methods and apparatus are provided for static and dynamic power management of computer systems. A power authority manages power usage levels in computer systems by monitoring power consumption levels and providing power consumption information to the various systems. In one example, the power authority updates power tables to vary aggregate power consumption levels.
Claims43
An apparatus, comprising:
- a plurality of computer systems, each computer system including a memory coupled to a processor and each computer system having a power consumption level, wherein an aggregate power consumption level comprises a combination of the power consumption levels associated with the plurality of computer systems;
- a power source providing power to the plurality of computer systems;
- a power authority subsystem for manipulating the aggregate power consumption levels by managing the power consumption levels of the plurality of computer systems.
A method for managing power consumption across multiple systems, the method comprising:
- identifying a maximum power output associated with a power supply configured to provide power to a first computer system and a second computer system;
- receiving power requirements information associated with the first and second computer systems;
- generating power consumption information using the power requirements information;
- providing power consumption information to the first and second computer systems, wherein power consumption information directs the first and second computer systems to run with an aggregate power consumption less than the maximum power output.
A computer readable medium comprising computer code for managing power consumption across multiple systems, the computer readable medium comprising:
- computer code for identifying a maximum power output associated with a power supply configured to provide power to a first computer system and a second computer system;
- computer code for receiving power requirements information associated with the first and second computer systems;
- computer code for generating power consumption information using the power requirements information;
- computer code for providing power consumption information to the first and second computer systems, wherein power consumption information directs the first and second computer systems to run at specified aggregate power consumption levels.
