摘要： Storage apparatus and data management methods provide for high-speed copying of a compressed data volume. A control unit of the storage apparatus divides a pool into a plurality of chunks including a plurality of pages storing data, compresses data which is written to a logical volume by a host, and assigns one of the plurality of chunks to a compressed data logical volume which stores the compressed data. When the compressed data logical volume is copied, the control unit makes a page length of the chunk assigned to the compressed data logical volume that is a copy source equivalent to a page length of the chunk assigned to the compressed data logical volume that is the copy destination.

摘要： For betterment, by putting a virtual storage device into a suspend mode, physical resources are turned OFF on a virtual storage device basis. Moreover, control information and volume data of the virtual storage device are stored in any external volume, for example, and the resources that have been used by the virtual storage device are deallocated. At the time of resumption of operation, using any resources not in use, the virtual storage device is restored based on the control information in storage. When a change is made to a WWN on the side of a host, the storage device receives a WWN change notification from a management server, and makes settings again to a WWN table, thereby making it accessible from the host.
摘要翻译：为了改善，通过将虚拟存储设备置于挂起模式，物理资源在虚拟存储设备的基础上被关闭。此外，虚拟存储装置的控制信息和卷数据被存储在例如任何外部卷中，并且由虚拟存储装置使用的资源被解除分配。在恢复运行时，使用任何未使用的资源，根据存储中的控制信息恢复虚拟存储设备。当对主机侧的WWN进行了更改时，存储装置从管理服务器接收到WWN变更通知，再次对WWN表进行设定，从而能够从主机访问。

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： An example of an information storage system includes physical storage drives for providing real storage areas to a pool which is tiered into tiers different in performance, and a controller. The controller monitors accesses in a first tier in the pool. The controller determines a loaded state of the first tier based on the accesses to the first tier. The controller holds management information relating loads to the first tier to relocation speeds and/or modes of moving data in data relocation between a second tier in the pool and the first tier. The controller determines at least one of a relocation speed and a mode of moving data in data relocation between the second tier and the first tier based on the determined loaded state of the first tier and the management information.

摘要： A storage apparatus for which a hierarchical data management system is adopted is designed so that when receiving a read request for a first logical area to which a first storage area of a first storage device in a virtual volume is allocated, whether or not to migrate data in a first storage area of the first storage device, to a storage area of a second storage device is decided according to an access frequency to the first logical area in synchronization with the read request. When it is decided that the data stored in the first storage area of the first storage device should be migrated to the storage area of the second storage device, the data is migrated to a second storage area of the second storage device and the second storage area thereof is allocated to the first logical area in the virtual volume.

摘要： In a storage system which supports a redundant disk configuration, while securing fault tolerance, a longer drive access time as well as a drop in I/O throughput are prevented when a redundant data update, generated due to a data update, is mirrored in the drive.A controller for controlling data I/O to and from the drive updates first redundant data and block data of a corresponding data stripe in the disk drive in correspondence with an update of block data of the logical volume, and the controller updates second redundant data on the basis of a predetermined number of block data which belong to the same data stripe as the updated block data with different timing from the update of the block data.
