摘要： According to the prior art storage system, in order to add a storage device to a pool after a storage system has been operated for a certain period of time, the performance may be varied significantly according to the access performance of the application using the pool, and it was not possible to realize an optimum allocation corresponding to the operation form if the storage device is set to be included in a pool of a given tier based on the type of the storage device. Therefore, the present invention provides a system in which a performance test is performed in accordance with an access tendency of the application using the pool to thereby compute the tier capable of having the storage device added thereto, based on which the storage device can be allocated to an appropriate pool.
摘要翻译：根据现有技术的存储系统，为了在存储系统已经运行一段时间之后将存储设备添加到池中，可以根据使用池的应用的访问性能来显着地改变性能，并且如果根据存储设备的类型将存储设备设置为包括在给定层的池中，则不可能实现对应于操作形式的最佳分配。因此，本发明提供一种系统，其中根据使用该池的应用的访问趋势来执行性能测试，从而计算能够添加存储设备的层，基于该层可以分配存储设备到适当的游泳池。

摘要： When a plurality of applications operating in a host computer or a storage system uses a same pool, actual data constantly allocated to an upper tier drive satisfying the required response performance will continue to increase. Therefore, when data is migrated by IOPS in page units, the access performance such as the response speed may not be satisfied. Therefore, according to the present invention, multiple virtual volumes used in applications are subjected to grouping. Relocation conditions corresponding to performances required for each group are set in advance, and reallocation of tiers according to the relocation conditions is performed.
摘要翻译：当在主计算机或存储系统中操作的多个应用程序使用相同的池时，持续分配给满足所需响应性能的上层驱动器的实际数据将继续增加。因此，当数据以页面为单位迁移IOPS时，可能无法满足访问性能，如响应速度。因此，根据本发明，在应用中使用的多个虚拟卷被分组。预先设定与各组所需性能相对应的搬迁条件，并根据搬迁条件重新分配层次。

摘要： An exemplary storage susytem of the invention processes requests to access a primary volume and a plurality of secondary volumes forming pairs with the primary volume. In each of the plurality of secondary volumes, address areas are defined which are respectively associated with address areas of the primary volume. Each of the plurality of secondary volumes stores differential data with respect to data in the primary volume. A controller monitors write accesses to the primary volume and the plurality of secondary volumes, and retains a monitoring result. The controller controls, based on, in the monitoring result, presence/absence of past write accesses to a plurality of areas in the primary volume and areas respectively corresponding to the plurality of areas in the plurality of secondary volumes, accesses to the primary volume.
