Abstract: A management system outputs catalog data, which has been created based on catalog-source data comprising data showing at least an application of a relevant resource with respect to each of multiple providable resources, and which shows the respective applications of the multiple resources, and receives a selection of a resource to be provided from the multiple resources. The management system provides the selected resource as a provided resource, and determines, based on a performance threshold configured with respect to the application of the provided resource, whether or not a performance measurement value, which relates to the processing performance of a network service using the provided resource and which can be monitored by the management system, is normal.

Abstract: It is an object to use a storage region in an efficient manner and maintain a performance of a storage system. A volume group GR11 includes reference volumes 1411, 1413, and 1415 and source volumes 1412, 1414, 1416, and 1417 that derive from the reference volumes. Each of the volumes stores only the difference data from a volume that is a parent thereof. A volume that is a cause of a problem is moved or copied from a pool of the moment 1410 to other pool 1420. A configuration of a volume group is modified.

Abstract: A computer system is provided that is capable of reducing an administrator's operational errors by connecting a new server to a SAN and automating a SAN boot setting, and capable of lightening the administrator's task of checking for a wrong connection by detecting a wrong connection made when a new server is connected to an SNW connection device. Once a new server connected to a PnP SAN starts with a boot program obtained from a boot management server, the new server transmits configuration information on the new server to a resource management server. In response to a request from the resource management server, a storage device refers to PnP SAN information to transmit SAN information on a storage network connection device to which the new server is connected. The resource management server determines to add the new server to a resource group on the basis of the SAN information and requirement information.

Abstract: Backup and restore operations are made possible in a storage system that has dynamic chunk allocation (DCA) capability. In a DCA storage system, a chunk of physical storage area is not allocated to a segment of a volume until a write command is received targeting the segment of the volume. During a restore operation of the volume in the DCA storage system, the wasting of storage capacity when a backup image of the volume is restored is mitigated by preventing allocation of physical storage areas to segments of restore data that are only void data.

Abstract: A storage system comprises a storage apparatus which includes a processor, storage disks, and a memory storing a page mapping table, a page mapping program, and a page-filename mapping program. A file system manages a file tree of files with filenames. The page mapping table specifies a relationship between data volumes in the storage apparatus and the storage disks and the file system, the data volumes each including pages, each page including segments, each segment including sectors. The file tree has for each storage apparatus a hierarchy of directories and files based on relationships among the data volumes, the pages, and the segments. The page mapping program and the page-filename mapping program are executable by the processor to specify, by page, a location of data contained in the I/O request by referring to the page mapping table and the file tree.
