Abstract
A method determines actual power consumption for system power performance states (SPP-states) of a server. The method comprises initializing the server, performing a worst case workload test, measuring power consumption of the server at one or more SPP-states, and adjusting values in a lookup table to reflect the measured power consumption of the server.
Claims22
A method for determining actual power consumption for system power performance states (SPP-states) of a server, the method comprising:
- initializing the server;
- performing a worst case workload test;
- measuring power consumption of the server at one or more SPP-states;
- and
- adjusting values in a lookup table to reflect the measured power consumption of the server.
2 more elements
A server comprising:
- a central processing unit (CPU);
- a power measurement circuit coupled to the CPU;
- a management processor coupled to the CPU, wherein the management processor is configured to select a system power performance state (SPP-state) from among plural SPP-states;
- and
- code executable by the CPU to:
- initialize the server;
- perform a worst case workload test;
- receive information regarding power consumption of the server measured by the power measurement circuit at one or more SPP-states;
- and
- adjust values in a lookup data structure accessible by the management processor to reflect the measured power consumption of the server.
7 more elements
A computer comprising:
- a power measurement circuit;
- and
- at least one processor to:
- receive a power measurement relating to power consumption in the computer from the power measurement circuit at each of plural system power performance states (SPP-states) while the computer is performing a workload test;
- and
- update values in a lookup data structure to reflect the power measurement at each of the SPP-states, wherein the lookup data structure is for use in selecting an SPP-state from among the plural SPP-states of the computer during operation of the computer.
