Abstract: A management system (A) assigns a priority to each of a plurality of elements matching a predetermined condition based on management information including information representing a relation among elements and information representing a metric of each of the elements, (B) displays a visual representing a visual priority given to each of element based on one or more priorities given in (A), (C) when receiving selection of the elements from the visual displayed in (B), selects a higher or lower level layer of a layer containing a selected element, and selects one or more elements related to the selected element and contained in the selected layer, based on a level relation among a plurality of layers and a correlation between element types and layers, and (D) performs (A) with the one or more elements selected in (C) treated as the one or more elements matching the predetermined condition.

Abstract: A management computer 3 configures a coordinate plane from a first axis, which denotes a performance value of a virtual machine 1, and a second axis, which denotes a performance value of a volume 2, 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 server 3 re-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.
