摘要： The present invention efficiently changes a volume size while maintaining a copy pair as-is. A PVOL and a SVOL #1 are in a pair state and are synchronized. The PVOL and a SVOL #2 are in a restore state. Upon instruction of expansion of the size of the PVOL, the size of a copy-destination SVOL #1 is first expanded, the size of the PVOL is then expanded, and the size of the SVOL #2 is lastly expanded. In the case of a PSUS state, only the size of the PVOL is expanded, and the size of the SVOL is left as-is.

摘要： A storage system comprises a virtual volume configured of multiple virtual areas and a pool configured of multiple actual area groups of different performances. The controller of the storage system manages which actual areas are assigned to which virtual areas and the access load on the actual areas assigned to the virtual areas. The controller, if the access load of a first actual area assigned to a first virtual area is inappropriate for a first actual area group comprising the first actual area, migrates data to a second actual area in a second actual area group which is appropriate for the access load of the first actual area from the first actual area. The controller performs data migration between actual areas for achieving data allocation at a certain point of time based on history information which is the information related to a virtual area at a point of time in the past and an actual area assigned to the virtual area. Data allocation is the allocation of data in a virtual area to an actual area in an actual area group.

摘要： A first virtual storage and a second virtual storage share an external LU (Logical Unit) inside an external storage. The first virtual storage comprises a first LU, which comprises multiple first virtual areas and conforms to thin provisioning, and an external capacity pool, which is a storage area based on the external LU, and which is partitioned into multiple external pages, which are sub-storage areas. The second virtual storage comprises a second LU, which comprises multiple second virtual areas and conforms to thin provisioning. In a data migration from the first LU to the second LU, for a data migration from a first virtual area, to which an external page has been allocated, to a second virtual area, the first virtual storage notifies the second virtual storage of a migration-source address, which is an address of the first virtual area, and an external address, which is an address of the external page that has been allocated to this virtual area, and the second virtual storage stores a corresponding relationship between the notified migration-source address and external address.

摘要： A second storage maps a migration source volume to a virtual volume of a migration destination volume according to storage virtualization technology. A host system including a host switches an access path from an access path to the migration source volume to an access path to the migration destination volume. The second storage executes copy processing of migrating, from the migration source volume to the migration destination volume, data in an assigned area of a virtual volume according to thin provisioning of the migration source volume based on the information contained in the first thin provisioning information in the first storage, and copying that data from the migration destination volume to a virtual volume according to thin provisioning of a copy destination volume in the second storage. The second storage associates the virtual volume of the copy destination volume with the migration destination volume in substitute for the original virtual volume.

摘要： With a computer system having a host computer and first and second storage apparatuses, the second storage apparatus virtualizes first logical units in the first storage apparatus and provides them as second logical units to the host computer, collects configuration information about each first logical unit, and sets each piece of the collected configuration information to each corresponding second logical unit. The host computer adds a path to the second logical units and deletes a path to the first logical units. The second storage apparatus copies data stored in the first logical units to a storage area provided by the second storage device and associates the storage area with the second logical units.

摘要： If a monitor measurement cycle is set as a long cycle, promotion in a short cycle cannot be performed; and even if the number of I/Os is very large in response to fluctuations of the number of I/Os in several minutes to several hours of normal work, pages will be promoted after waiting for several weeks. As a result, I/Os which could have normally accepted by an upper tier will be accepted by a lower tier, which results in a problem of worsening the performance efficiency. A monitoring system capable of preventing demotion due to temporary reduction of the number of I/Os for specific pages from a viewpoint of a long cycle and enabling prompt promotion in response to an increase of the number of U/Os for 3 the specific pages is realized.A load index value defined from a viewpoint of a long cycle and a load index value defined from a viewpoint of a short cycle are updated based on the number of I/Os which is counted cyclically for each storage area. Promotion and demotion are implemented based on a value(s) calculated from these load index values.

摘要翻译： 如果监视器测量周期设置为长周期，则不能执行短周期的升级; 即使I / O的数量在正常工作的几分钟到几个小时内因I / O数量的波动而非常大，等待几周后页面也会被提升。 因此，上层通常可以接受的I / O将被下层接受，导致性能效率恶化的问题。 能够从长周期的观点对特定页面的I / O数量的暂时减少进行防止降级的监视系统，能够响应于特定页面的3的U / Os的数量的增加而能够及时的提升， 实现了 基于对于每个存储区域循环计数的I / O的数量，更新从从短周期的角度定义的长周期和负载指标值的观点定义的负载指标值。 基于从这些负荷指数值计算的值来实现升级和降级。

摘要： In general, a DRAM is used as a cache memory, and when attempting to expand the capacity of the cache memory to increase the hit ratio, the DRAM is required to be physically augmented, which is not a simple task. Consequently, a storage system uses a page, which conforms to a capacity virtualization function (for example, a page allocatable to a logical volume in accordance with Thin Provisioning), as a cache area. This makes it possible to dynamically increase and decrease the cache capacity.

摘要翻译： 通常，将DRAM用作高速缓冲存储器，并且当试图扩大高速缓冲存储器的容量以增加命中率时，需要物理地增加DRAM，这不是一项简单的任务。 因此，存储系统使用符合容量虚拟化功能（例如，根据精简配置的可分配给逻辑卷的页面）作为缓存区域的页面。 这使得可以动态地增加和减少高速缓存容量。
