Abstract: A management method and management apparatus that can prevent deterioration of response performance of an entire system is suggested.

Abstract: Power savings for a storage apparatus while preventing a drop in response performance is achieved. When the storage area supplied by the memory apparatus groups is not accessed by the host apparatus for a predetermined period, stop operation is performed for each of the memory apparatuses configuring the memory apparatus groups. The management apparatus groups, among the resources, resources with overlapping time zones for which the number of accesses by the application is zero, in the same group, and maps each of the groups to the memory apparatus groups respectively. At this time, if the number of accesses in each of the time zones of the groups of resources mapped to the memory apparatus groups exceeds the reference value of the memory apparatus groups, the group is divided into a plurality of groups and each of the plurality of groups is mapped to the memory apparatus groups.

Abstract: To solve a problem in that reliable detection of a performance problem caused by a configuration change needs detailed performance information, which is costly to keep and analyze, a management computer which manages a computer system having a host computer and a storage system is provided. The management computer is configured to: store performance information obtained from resources that belong to paths at first time intervals until a predetermined length of time elapses since the detection of an addition or removal of the resources to the paths; store performance information obtained from the resources that belong to the paths at second time intervals, which are longer than the first time intervals, without storing performance information obtained from the resources that belong to the paths at the first time intervals after the predetermined length of time elapses since the detection of the addition or removal of the resources to the paths.

Abstract: Performance of a storage subsystem is monitored at a proper level in a computer system having host computers, the storage subsystems, and a management computer. Each storage subsystem has physical disks and a disk controller to control input/output of the data to/from the physical disks. The disk controller provides storage areas of the physical disks as one or more logical volumes to the host computer. The management computer makes each of the logical volumes correspond to one of a plurality of groups, sets monitoring conditions of the logical volumes every group, monitors performance information of the logical volumes in accordance with the set monitoring conditions, and if a correspondence between the logical volume and the group is changed, changes the monitoring conditions set to at least one of the plurality of groups.
