    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: Proposed is technology for shortening the time required for analyzing and processing commands issued from multiple hosts and speeding up the processing. When a controller receives a command including random IO processing and the reception of commands is complete, it determines whether the valid extents prescribed in seek parameters attached to an LOC command overlap, and executes extent exclusive wait processing which causes access to the logical volume to enter a wait state or access processing to the logical volume based on the determination result. If the reception of commands is incomplete, the controller determines whether the access ranges (extents) designated in a DX command overlap, and executes extent exclusive wait processing or access processing to the logical volume based on the determination result.

    摘要: Provided is a storage system enabling the addition of a storage apparatus without going offline. When a first storage apparatus receives from a host system a command for writing first data in any one of the primary volumes in a primary volume group, it writes the first data in the relevant primary volume and sends to a second storage apparatus a first command for writing the first data in a secondary volume specified using first mapping information. When the second storage apparatus receives from the host system a command for writing second data in any one of the secondary volume groups in a secondary volume group, it writes the second data in the relevant secondary volume and sends to the first storage apparatus a second command for writing the second data in a primary volume specified using second mapping information.

    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: 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.
