ABSTRACT:
There is provided a method of controlling power consumption of a memory, which is executed in a computer system including operation server and a management server. The operation server includes one or more memory chips which are units to control the power consumption of the memory, a power control module for controlling power consumption of the memory chips, and a virtualization module for operating one or more virtual servers. The management server manages the mapping between the one or more virtual servers and the one or more memory chips. The method comprises the steps of instructing the operation server to change the power consumption of the one or more memory chips based on whether the obtained access information is capable of achieving predetermined target performance and the mapping information, and changing the power consumption of the one or more memory chips based on the instruction from the management server.
