Abstract: In a computer system, even when the virtual storage capacity of pools is increased, it is possible to keep the availability of each pool at least at a desired level. The managing server compares a reference value beforehand stored therein with an evaluation value of availability which represents a degree of resistivity against destruction, the degree being derived by use of physical configuration information which is obtained from the controller and which is associated with the pool; and determines necessity of addition of an element to the pool if the availability evaluation value exceeds the reference value and indicates the addition of the element to the pool to the storage apparatus.

Abstract: 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.

Abstract: In a storage operation management system, upper and lower limits of a level threshold of a volume to be selected from a characteristic value of a volume management table are calculated and the volume within the range is presented to a user as an allocation candidate.
