    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: 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: The present invention creates a pool comprising tiers corresponding to the performance of logical volumes.A first storage apparatus either acquires or measures the performance of multiple external pool volumes of an external storage (S1711 through S1714), and creates a pool volume group based on the performance of the external pool volumes (S1715, S1716). The rank order of a tier is decided in accordance with the performance of each pool volume group (S1717, S1718). This makes it possible to relatively easily create a pool comprising multiple appropriate tiers that are suited to the current situation.

    摘要: This computer system includes a first storage system and a second storage system. The first storage system has a data transfer unit for transferring the data stored in the first volume to the second volume of the second storage system. The second storage system has a snapshot creation unit for creating a snapshot of the second volume in a third volume based on a snapshot creation command. When the snapshot creation unit receives the snapshot creation command while transferring the data from the first volume to the second volume with the data transfer unit, it delays the creation of the snapshot of the second volume in the third volume until the transfer of the data from the first volume to the second volume is complete.
