Storage management method, storage management program, storage management apparatus, and storage management system

摘要

A storage management method for allocating a dynamic allocation pool so as to avoid throughput reduction. An operation management server determines the dynamic allocation pool managing allocation of a real volume in a storage device to a virtual volume. The operation management server acquires an I/O characteristic of an application being executed in a business server, records I/O characteristic information indicative of a linkage between the application and the I/O characteristic of the application for the each application in an application management table, creates an application group on the basis of the I/O characteristics of the application management table for the each application, and links the created application group to the dynamic allocation pool.
