    摘要: The storage control device of the present invention uses a plurality of queues to manage cache segments which are in use, so as to retain cache segments which contain large amounts of data for long periods of time. One of the queues manages segments in which large amounts of valid data are stored. Another queue manages segments in which small amounts of valid data are stored. If the number of unused segments becomes insufficient, then a segment which is positioned at the LRU end of the other queue is released, and is shifted to a free queue. Due to the use of this other queue, it is possible to retain segments in which comparatively large amounts of data are stored for comparatively long periods of time.

    摘要: The present invention continues host access and holds data of a migration source volume as the latest data even when a fault occurs in any of a plurality of access paths.Upon receiving a first write command from a host computer via a first access path, the migration source controller writes first update data to the migration source volume and, upon receiving a second write command from the host computer via a second access path, the migration destination controller transfers second update data to the migration source controller via a storage path and, upon receiving the second update data from the migration destination controller, the migration source controller writes the second update data to the migration source volume.

    摘要: To efficiently manage data including control information.A storage apparatus connected to a host requesting data writing includes one or a plurality of storage devices and a controller for allocating a storage area in page units to an area of a virtual volume to write the data in response to a request from the host to write the data wherein if the data regarding which the host makes the write request includes control information and data excluding the control information is specified data, the controller releases the allocation of the page allocated to the area for writing the relevant data.

    摘要: Each actual page inside a pool is configured from a plurality of actual tracks, and each virtual page inside a virtual volume is configured from a plurality of virtual tracks. A storage control apparatus of a mainframe system has management information that includes information denoting a track in which there exists a user record, which is a record including user data (the data used by a host apparatus of a mainframe system). Based on the management information, a controller identifies an actual page that is configured only from tracks that do not comprise the user record, and cancels the allocation of the identified actual page to the virtual page.

    摘要: A storage apparatus comprises a disk device and a disk adapter for controlling the disk device. The disk adapter controls the disk device and forms a data volume and a pool volume, creates a data block for parity data, compresses write data and the created parity data, and stores a number of compressed data blocks equal to or less than a predetermined number and stores compressed parity data that are within a predetermined size in storage areas in an actual volume, and stores the remaining compressed data blocks of a number greater than the predetermined number and compressed parity data that exceed the predetermined size in storage areas in the pool volume corresponding to a virtual volume.

    摘要: When a double failure occurs in a storage device storing a mutual conversion table such as a track management information table in thin provisioning, the storage address of the track within the storage subsystem cannot be specified and user data is lost. In order to solve the problem, the present invention provides a storage subsystem capable of recovering data by referring to a track address stored in an accessible track management information table or a user data section, renewing the damaged track management information table to restore the corresponding relationship between track management information tables, and enabling the user data to be accessed again.
