摘要： 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.

摘要： A first computer is provided that executes a plurality of virtual machines (VMs), a storage device, and a second computer is provided that applies patches to OSs (operating systems) operating upon the VMs to the VMs. The storage device holds storage regions (golden images (GIs)) that store data of the OSs operating upon the VMs at certain time instants, a storage region (i.e. a storage pool) that stores patches applied to the OSs of the VMs after those certain time instants, and snapshots of the GIs. Patches applied to the OSs of the VMs accessed in the snapshots are stored in the storage pool. The second computer selects, as a GI to be a source of acquisition of snapshots, a GI to which are applied patches of a combination that can be created from patches applied to the OS of some VM, and deletes patches that are patches applied to the selected GI, and that moreover, among the patches applied to that VM, are stored in the storage pool.

摘要： Since only one golden image (GI) of a snapshot can exist and is shared among a plurality of storage apparatuses, there was a problem that migration or copy thereof deteriorates the capacity efficiency and increases the cost for managing consistency. The present invention solves the above-mentioned problem by either (1) a direct sharing method of generating a parent-child relationship of snapshots among different storage apparatuses at the time of creating differential LUs from the GI or (2) a virtual sharing method of creating virtual LUs of the GI in the respective storage apparatuses and creating differential LUs of the snapshots from the created virtual LUs, using a storage virtualization function among a plurality of storage apparatuses.

摘要： When migrating a virtual server between a plurality of physical servers, a pre-migration connection relationship between the virtual server and a storage area used by the virtual server is maintained after the migration of the virtual server by using a cooperative mechanism between a plurality of storage apparatuses even if the storage area used by the virtual server is migrated between the plurality of storage apparatuses. A computer system includes: a first system having a first physical server, a first storage apparatus, and a first network for connecting them; a second system having a second physical server, a second storage apparatus, and a second network for connecting them; and a management computer for managing the first system and the second system. When the management computer accepts information for designating a virtual server to be migrated from the second physical server to the first physical server, the management computer: stores a storage area used by the virtual server and specifies a migration target volume existing in the second storage apparatus; sets a migration destination volume, which is a migration destination of the migration target volume, in the first storage apparatus by associating the migration destination volume with the migration target volume by means of a cooperative function between the second storage apparatus and the first storage apparatus; specifies a connection relationship between the virtual server and the storage area stored in the migration target volume; and sets the connection relationship to the migration destination volume when migrating the virtual server from the second physical server to the first physical server.

摘要： A storage apparatus of an embodiment of the invention including one or more storage drives for providing real storage resources and a controller for controlling the one or more storage drives and accesses from a host computer. The controller initializes real storage resources and manages the initialized real storage resources. The controller receives an instruction for allocating an initialized real storage resource to a first virtual storage resource accessed by the host computer. In response to the instruction, the controller allocates a first initialized real storage resource which has been initialized in advance prior to the instruction to the first virtual storage resource.

摘要： The threshold excess is judged by a peak value, and therefore, since the threshold excess is judged by a value of high-workload IO of backup or the like that is designed on the assumption that the workload of storage is high, whether the performance limit has been reached remains uncertain. Furthermore, although an optimistic prediction trend with low workload trend and a pessimistic prediction trend with high pessimistic workload trend are presented, LUs that require improvement remain uncertain. Moreover, the time to improve the configuration and the effect of the improvement remain uncertain, and therefore, an improved configuration cannot be determined. Configuration information, performance information, and operation information are acquired from a storage, a performance limit excess time is predicted based on the performance information excluding LUs exceeding the performance trend, and an optimal improved configuration is determined from the performance limit after improvement and the time required for the improvement.
摘要翻译：阈值过剩由峰值判断，因此，由于通过假设存储量高的设计设计的备份等的高工作负载IO的值来判断阈值过剩，因此性能极限已经达到了不确定性。此外，虽然呈现出低工作量趋势的乐观预测趋势，以及悲观的工作量倾向悲观的预测趋势，但需要改进的LU仍然不确定。此外，改善配置的时间和改进的效果仍然不确定，因此，不能确定改进的配置。从存储器获取配置信息，性能信息和操作信息，基于不超过性能趋势的LU的性能信息来预测性能限制超时，并且根据改进后的性能限制和时间来确定最佳改进配置需要改进。
