Abstract
A storing unit stores therein mapping management information indicating mappings between each of a plurality of divided regions created by dividing logical storage space on a storage apparatus and one of a plurality of identification numbers each representing a different write frequency. A control unit measures the write frequency of each of the plurality of divided regions and updates the mappings indicated by the mapping management information based on results of the write frequency measurement. Upon request for a data write to a write address included in a divided region after the update of the mappings, the control unit identifies an identification number associated with the divided region based on the mapping management information, appends the identified identification number to a write request for the write address, and transmits the write request with the identified identification number appended thereto to the storage apparatus.
