Abstract
A server system includes a control device and plurality of server devices. The control device calculates an actual power consumption of the server system and notifies the actual power consumption to the server devices. Each server device compares the actual power consumption with a threshold value, and restricts power consumption of the server device based on a power-saving policy for the server device that represents a lower limit of power usable by the server device when the actual power consumption is greater than or equal to the threshold value.
Claims13
A computer-readable recording medium that stores therein a computer program that causes a computer in a computer system to execute:
- comparing actual power consumption of the computer system with a threshold value;
- and
- restricting power consumption of the computer based on a power-saving policy for the computer that represents a lower limit of power usable by the computer if a result of comparison at the comparing indicates that the actual power consumption is greater than or equal to the threshold value.
A server system comprises a control device and plurality of server devices, wherein
- the control device includes
- a calculating unit that calculates an actual power consumption of the server system;
- and
- a notifying unit that notifies the actual power consumption to the server devices, and
- each server device includes
- a comparing unit that compares the actual power consumption with a threshold value;
- and
- a curtailing unit that restricts power consumption of the server device based on a power-saving policy for the server device that represents a lower limit of power usable by the server device if a result of comparison by the comparing unit indicates that the actual power consumption is greater than or equal to the threshold value.
A power control method realized on a server system that includes a control device and plurality of server devices, wherein
- the control device performing
- calculating an actual power consumption of the server system;
- and
- notifying the actual power consumption to the server devices, and
- each server device performing
- comparing the actual power consumption with a threshold value;
- and
- restricting power consumption of the server device based on a power-saving policy for the server device that represents a lower limit of power usable by the server device if a result of comparison at the unit indicates that the actual power consumption is greater than or equal to the threshold value.
