Abstract
A group generation unitregards, as an invalid area, an area of a first storage medium in which data to be updated is stored and stores updated data in the first storage medium. A reorganization processing unit executes a process of selecting some first groups, calculating, for each of the selected first groups, the number of second storage media to be secured to store data that is stored in an area other than the invalid area of the first storage medium, securing the second storage media according to the levels of priority that are determined according to the calculated number, and transferring the data that is stored in the area other than the invalid area of the first storage medium to the second storage media. A volume management unit moves, to a second group, the first medium on which the transfer performed by the reorganization processing unit completes.
