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： There is provided a storage subsystem having a virtual volume and a page volume which has a page physical area allocated to the virtual volume. The storage subsystem divides an address space of the virtual volume into a plurality of pages, classifies each of the pages into one of a plurality of states including at least a first state and a second state, and further divide a page which is classified into the second state into a plurality of segments to managed the page classified into the second state. The first state is a state in which a page physical area is allocated to the page from the page volume, and the write data is stored in the page physical area. The second state is a state in which the predetermined pattern data and the segment are managed, in the memory, by correlating with each other.

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： A plurality of CPU cores each have control rights for logical storage areas of one or more types among logical storage areas of a plurality of types. As a source for an area to be assigned to the logical storage areas, a physical storage area which is common to the logical storage areas of the plurality of types is managed. Each CPU core, in the case of a data access to a logical storage area corresponding to the control rights of the CPU core, assigns an area required to store the data from the common physical storage area.

摘要： This invention is intended for the purpose of providing the storage system, the storage apparatus, and the storage system by which, even if the storage areas allocated to the virtual volume are managed in management units set by the RAID group, overhead for parity calculation does not become excessive. This invention, by releasing a specific management unit not fully utilized for page allocation from allocation to the virtual volume and migrating the allocated pages belonging to this specific management unit to the other management unit, makes the storage areas of the specific management unit available for the write accesses for the other virtual volumes from the host computer.
