Abstract
A storage system comprises multiple first storage apparatuses, and a controller which provides a first logical volume corresponding to a storage area of the multiple first storage apparatuses to a host computer. The controller partitions a storage area corresponding to the first logical volume into multiple first physical storage areas, manages the partitioned multiple first physical storage areas as physical storage areas of a storage pool, creates a first virtual volume which is provided to the host computer, and associates, from among the multiple first physical storage areas, a physical storage area in which user data is stored, with the first virtual volume.
