    摘要: Improving response time performance by executing exclusive extent processing of a plurality of I/O requests is proposed. A storage apparatus, which includes a plurality of microprocessors, a first memory which stores counter values indicating the order of the I/Os to and from the storage areas, and a second memory which stores control information of the I/O requests for each of the I/O requests, is configured such that the microprocessors store, if there is one I/O request from the host apparatus, an I/O request range of the one I/O request in an area for storing control information of the one I/O request of the second memory, the microprocessors acquire the counter value from the first memory and store the counter value in the area for storing control information of the one I/O request of the second memory, and the microprocessors compare, if the counter value of the one I/O request is greater than the counter value of another I/O request, the I/O request range of the one I/O request stored in the second memory with the I/O request range of the other I/O request.

    摘要: A storage apparatus includes a microprocessor package configured to access a logical volume and a local memory in the microprocessor package. An input/output (I/O) request range of one I/O request, including a start position address and an end position address of the logical volume which is a target of the one I/O request, is stored in the local memory. A counter value indicating a number of I/O requests to and from the logical volume associated with the one I/O request is acquired and stored in the local memory. If the counter value associated with the one I/O request is greater than the counter value associated with another I/O request, the I/O request ranges of the one I/O request and the other I/O request are compared. If there is no overlap between the I/O request ranges, the one I/O request is executed; otherwise, the one I/O request is placed on standby.

    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: A storage apparatus comprises a disk device and a disk controller for controlling the disk device. The disk controller provides a data volume including an actual volume and virtual volume with a volume capacity virtualization function. The virtual volume is associated with a pool volume for storing the actual data and the actual data is stored in the pool volume. In response to a write command from a host computer, the disk controller compresses write data under RAID 5 control and stores the compressed data in a storage area in the actual volume. If the entire compressed data cannot be stored in that storage area, the disk controller stores the remaining portion of the compressed data in the virtual volume.

    摘要: A method and system are provided that can realize data migration between volumes accessed by a host computer without stopping the host computer accessing the volumes.A host computer 10 is connected to a storage subsystem 14 via paths 54 and 56, and the storage subsystem 14 is connected to a storage subsystem 12 via a path 58 (or paths 58 and 60). While data is being copied from an old volume 62 in the storage subsystem 12 (a migration source) to a new volume 64 in the storage subsystem 14 (a migration destination) via the path 58 (or paths 58 and 60), if a request for I/O processing is sent from the host computer 10, the storage subsystem 14 responds and handles that I/O processing.
