    摘要: A storage system assigns a real area from a pool to a virtual area in a virtual volume, and stores data into the real area. The pool comprises a plurality of real areas based on a plurality of types of storage devices with different characteristics, and the plurality of real areas are managed as a plurality of tiers depending on the characteristics of the storage devices. Moreover, the storage system moves the data from one tier to another tier in the pool, for each real area.

    摘要: A storage management program is provided with a function of determining a suspension/continuation of a remote backup based on an operation-at-failure management table, and accomplishes the suspension/continuation of the backup based on the application in which a failure has occurred and the mode of this failure. The storage management program is also provided with a function of computing a change in the quantity of data from the last backup before the occurrence of the failure until the first backup after the occurrence of the failure, and determining the suspension/continuation of the backup, enabling to suspend/continue the backup in line with the operating status of the application.

    摘要: A storage system which has flash memories constituting a storage area and a function of placing and handling the flash memories in on-line mode and off-line mode, and which stores and manages management information of the flash memories in on-line mode. The storage system includes: when some or all of flash memory in on-line mode is placed in off-line mode, creating a management area in off-line mode in the flash memories by moving existing data in an area used as the management area to an area other than the management area; writing the management information of the flash memories to the created management area; and placing the flash memories in off-line mode.

    摘要: A management computer manages the pool application information that indicates a pool application for a pool and the application condition information that indicates the condition for the pool application. The management computer calculates an excess storage capacity based on a pool usage status for the pool. The management computer specifies a pool application for the pool and the condition for the pool application based on the pool application information and the application condition information. The management computer judges whether the specified condition is satisfied even in the case in which a storage area having a storage capacity equivalent to or less than the calculated excess storage capacity is deleted from the pool. In the case in which the result of the judgment is positive, the management computer defines a capacity equivalent to or less than the excess storage capacity as an unused capacity.

    摘要: In a storage system 1, a storage apparatus A having a first pool 1430 including segments as unit storage areas and a storage apparatus B having a second pool 1430 having the same configuration are communicably connected to each other. In the storage system, an external volume identifier is associated with a logical volume 1420 included in the first pool 1430, the external volume identifier being used by a controller 1500 in the storage apparatus B to identify and manage the logical volume 1420 as an external volume 1425 that is a virtual volume in the storage apparatus B. Moreover, a volume identifier 5110 of the logical volume 1420 included in the first pool 1430 is rewritten into the external volume identifier in order to enable the storage apparatus B to utilize the logical volume 1420 created from the first pool 1430.
