Beschreibung
Zusammenfassung:	The storage device of the present invention has: a first recording unit that records a time zone history of access to each storage area assigned to a virtual volume; a second recording unit that executes a predetermined calculation based on the time zone history of access to a plurality of storage areas belonging to a plurality of pool areas and records the calculation result for each of the plurality of pool areas; a comparison unit that acquires, from the first recording unit, the time zone history of access to an optional storage area among the plurality of storage areas and compares the acquired access time zone history with the calculation result recorded in the second recording unit; and a migration unit that selects, from among the plurality of pool areas, a pool area for which the calculation result is similar to the acquired access time zone history on the basis of the result of the comparison by the comparison unit, and migrates the data stored in the optional storage area to a storage area in the selected pool area.
