摘要： Two or more first storage control apparatuses (DKC) comprise two or more virtual volumes and two or more storage devices, and a pool, which is configured by multiple actual areas, is formed on the basis of the two or more storage devices. A second DKC determines, for each storage device, an unused capacity to be given to the first DKC with respect to each first DKC based on an unused capacity of each storage device and a request value of each storage device for each first DKC, and gives, for each first DKC, the unused capacity for each storage device determined with respect to the first DKC, to this first DKC. The request value of the storage device is based on a performance value, which is a value related to the performance of this storage device. The total capacity of multiple actual areas allocated to one or more virtual volumes by the first DKC is equal to or less than the unused capacity given with respect to each storage device.

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： 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 I/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，则不能执行短周期内的升级; 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。能够防止由于从长周期的观点对特定页面的I / O数量的暂时减少而能够防止降级的监视系统，并且能够响应于特定页面的3的I / O数量的增加而能够及时促进实现。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： 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： In a storage system which includes a plurality of microprocessors, it is desired to prevent delay in I/O responses due to synchronous processing waiting for asynchronous processing, while still ensuring the throughput of asynchronous processing. In a plurality of microprocessors possessed by a controller, synchronous processors and asynchronous processors are mixed together. The synchronous processors are microprocessors whose duty is to perform synchronous processing and not to perform asynchronous processing. And the asynchronous processors are microprocessors whose duty is to perform asynchronous processing and not to perform synchronous processing.

摘要： A first storage control apparatus unit comprises a first logical volume. A second storage control apparatus unit comprises a second logical volume, which is a virtual logical volume and is mapped to the first logical volume, and a third logical volume that is associated with the first logical volume. The second storage control apparatus unit receives, from a host, an I/O command which comprises information including, as information denoting an I/O-destination area, an ID of the second logical volume and an address of an area of the second logical volume. The second storage control apparatus unit identifies a logical volume comprising an area that serves as an entity of the I/O-destination area, and a storage control apparatus unit that comprises this logical volume. In a case where the second storage control apparatus unit and the third logical volume have been identified, the second storage control apparatus unit carries out an I/O with respect to the area that serves as the entity of the I/O-destination area in the third logical volume.
