摘要： A generation section periodically generates access frequency information for identifying an access frequency of each data item according to a status of write access of the data item transmitted from a host device to a storage device. Whenever access frequency information is generated by the generation section, a determination section determines whether to write data saved in a hard disk into the storage medium, or to hold a saved state of the data. A write section writes data into the storage device according to determination by the determination section.

摘要： A storage control apparatus includes a controller for receiving an access command from a host computer and controlling an access to a storage device and a monitoring period obtaining section for obtaining a monitoring period corresponding to the access command. The storage device is capable of operating in one of a power saving state and a normal state. The controller causes the storage device to return from the power-saving state to the normal state if the storage device corresponding to the access command is in the power saving state, and sends the host computer a response for preventing a timeout corresponding to the access command if the storage device have not yet returned to the normal state when the monitoring period elapses from receiving the access command.
