A burden placed on an administrator in creating a volume is reduced. An evaluation hint value and a performance hint value are employed as hint values for each hint. The evaluation hint value is determined by the administrator considering a service usage and the like of the service server 1 to which the volume is allocated. The performance hint value is used to determine a performance and a setting of the volume to be created in the storage system 3. The management server 2 has a conversion table indicating a correspondence between the evaluation hint value defined considering the hardware configuration and the performance hint value, with respect to each storage system 3. The management server 2 converts the evaluation hint value designated by the administrator to a performance hint value, by use of the conversion table associated with the storage system to which the volume is to be created, and the management server creates the volume in the storage system 3 according to the performance value.
