Abstract
An information processing apparatus includes a plurality of storage units, a mirroring control unit configured to execute mirroring processing, which includes writing processing for writing same data on each of the plurality of storage units and reading processing for reading data from either one of the plurality of storage units, and a power control unit configured to independently control supply of power to the plurality of storage units. If the supply of power to the plurality of storage units is reduced, if the mirroring control unit starts the writing processing, the information processing apparatus resumes the power supply to the plurality of storage units, and if the mirroring control unit starts the reading processing, the information processing apparatus resumes the power supply to a specific storage unit from which the data is read, and configured to execute control not to resume the power supply to the other storage unit(s).
