Abstract
A management computerconfigures a coordinate plane from a first axis, which denotes a performance value of a virtual machine, and a second axis, which denotes a performance value of a volume, and partitions this coordinate plane into multiple areas in accordance with a prescribed criterion. The management server computes to which area of the areas a pair configuration of a virtual machine and a logical volume belongs, and stores the result. At a prescribed time, the management serverre-evaluates a coordinate of the pair configuration, and determines whether or not an initial area and a latest area match. The management server creates a migration plan so that the latest area matches the initial area.
