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： 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： 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.
摘要翻译：本发明的存储控制装置使用多个队列来管理正在使用的高速缓存段，以便在长时间段内保留包含大量数据的高速缓存段。其中一个队列管理存储大量有效数据的段。另一个队列管理存储少量有效数据的段。如果未使用的段数不足，则释放位于另一个队列的LRU端的段，并将其移动到空闲队列。由于使用了这个其他队列，所以可以保留相对较长时间内存储相对大量数据的段。

摘要： A controller 2 uses a virtual logical volume 3 having an expandable volume size to perform either a remote copy or an internal copy without suspending access from a host. The virtual logical volume 3 is able to expand a volume size in units of a cylinder group 6 that have a size equivalent to 25 pages. Information for managing a copy is stored in a control area 6B inside the cylinder group 6. This enables storing of copy management information in accordance with the expanded size of the virtual logical volume.

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： 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： 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.
