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： 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 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： 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： 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.
摘要翻译：提出的技术是缩短分析和处理从多台主机发出的命令所需的时间并加快处理的技术。当控制器接收到包括随机IO处理并且命令的接收完成的命令时，它确定附加到LOC命令的寻求参数中规定的有效范围是否重叠，并且执行扩展独占等待处理，这导致对逻辑卷的访问进入基于确定结果等待状态或对逻辑卷的访问处理。如果命令的接收不完整，则控制器确定在DX命令中指定的访问范围（扩展区）是否重叠，并且基于确定结果对逻辑卷执行扩展独占等待处理或访问处理。
