Abstract
An object of the present invention is to efficiently use a hierarchical pool. A management server manages performance information of multiple host computers, and based on each performance information, determines whether a prescribed host computer, which comprises a load of equal to or larger than a preconfigured prescribed threshold, exists among the multiple host computers. The management server creates a reallocation plan, which stipulates an allocation amount of a real storage area for each of multiple storage tiers, with respect to a prescribed virtual logical volume used by the prescribed host computer. Based on the reallocation plan, the management server decides a corresponding relationship between each logical storage area and each real storage area of each storage tier, and notifies a storage apparatus of this corresponding relationship.
