Abstract
A receiving unit receives an input of information of a performance level with respect to a volume that is allocated by using different types of disks. A target value calculating unit calculates, on the basis of a distribution ratio that is previously determined for each type of the disks, a target value of the performance of sending and receiving data to and from the volume. On the basis of the target value calculated by the target value calculating unit, a performance management unit determines a distribution ratio for each type of the disks allocated to the volume, determines a band distribution with respect to the volume, and instructs the storage device to re-allocate the volume by using the determined distribution ratio and adjust the bandwidth in accordance with the determined band distribution.
