Abstract
A method for adjusting power consumption during server operation is disclosed. The method comprises initializing the server to a system power performance state (SPP-state) that comprises a plurality of constituent power settings, determining whether power regulation is required while the server is operating at the current SPP-state, setting a flag if power regulation is required, and increasing at least one of the plurality of constituent power settings associated with the SPP-state if the flag has been set.
Claims19
A method for adjusting power consumption during server operation, the method comprising:
- initializing the server to an initial system power performance state (SPP-state) that comprises a plurality of constituent power settings contained in a table;
- modifying at least one of the plurality of constituent power settings stored in the table;
- and
- comparing a maximum power consumption threshold to a power consumption measurement at the initial SPP-state and reducing at least one of the plurality of constituent power settings associated with the initial SPP-state if the maximum power consumption threshold is less than the power consumption measurement at the initial SPP-state.
A server comprising:
- a central processing unit (CPU);
- a management processor coupled to the CPU via a bus, wherein the management processor adjusts power consumption according to executable code, the code causes the management processor to:
- initialize the server to an initial system power performance state (SPP-state) that comprises a plurality of constituent power settings contained in a table;
- during a boot process, negotiate power consumption for the server with a management device external to the server;
- and
- modify at least one of the plurality of constituent power settings stored in the table based on the negotiated power consumption for the server.
A server comprising:
- a central processing unit (CPU);
- a means for managing power within a server coupled to the CPU, the means for managing power performs a method comprising:
- initializing the server to an initial system power performance state (SPP-state) that comprises CPU frequency and clock modulation settings contained in a table;
- and
- comparing a maximum power consumption threshold to a real-time power consumption measurement for the initial SPP-state and reducing at least one of the CPU frequency and the clock modulation settings associated with the initial SPP-state if the maximum power consumption threshold is less than the real-time power consumption measurement for the initial SPP-state.
