Abstract
A pool, which is configured by multiple actual areas, is formed on the basis of two or more storage devices. A second storage control apparatus (DKC) determines, for each storage device, an unused capacity to be given to a first DKC with respect to each first DKC based on an unused capacity of each storage device and a request value of each storage device for each first DKC, and gives, for each first DKC, the unused capacity for each storage device determined with respect to the first DKC, to this first DKC. The request value of the storage device is based on a performance value, which is a value related to the performance of this storage device. The total capacity of multiple actual areas allocated to the virtual volumes by the first DKC is equal to or less than the unused capacity given with respect to each storage device.
