Abstract
A power-saving control apparatus and method capable of power-saving and prevention of decrease in the speed of accessing files of a high level of importance is suggested.First file migration processing is executed for detecting a user access pattern for each file stored in a storage apparatus, grouping files of similar access patterns based on the detected access patterns, migrating each of the grouped files, by group, to memory media individually capable of power-saving control, and setting a power-saving control schedule for each group based on the access pattern for each file; and power-saving control of each memory medium is executed in accordance with the schedule set for each group; wherein the power-saving control schedule for each group is set based on the access pattern of the file whose level of importance is set to the highest level, from among the files belonging to that group.
