Abstract
An operational management server manages a storage device that includes a plurality of types of disks having different performances. A setting unit sets a target value of a performance to a volume produced by using the different types of the disks. An allocation rate management unit determines allocation rates of the respective types of the disks included in the volume on the basis of the target value set by the setting unit, and instructs the storage device to reproduce the volume in accordance with the determined allocation rates.
