STORAGE CONTROL DEVICE AND STORAGE CONTROL METHOD FOR CACHE PROCESSING ACCORDING TO TIME ZONES

A storage control device capable of avoiding a decrease in performance related to accesses to a storage device from a start time of a certain time zone is provided. A schedule information storing unit 130 stores schedule information indicating target data in an access to a storage device in a predetermined time zone. The target data is a target of a cache control using a cache memory. A cache processing unit 120 performs the cache control for the access to the target data and an access to data other than the target data in a time zone except the predetermined time zone, and performs the cache control for the access to the target data in the predetermined time zone. A preprocessing unit 140 performs a preprocessing to make the cache memory available for the cache control of the target data by a start time of the predetermined time zone.
