    摘要： A plurality of commands which may be sent sequentially from a host computer are interpreted by a host command interpreter to generate a disk command for each disk unit. When these commands make up an access demand for a single continuous area, they are grouped into a single command, which is executed substantially at the same time at each disk unit. Also, a plurality of RMW processing systems having different command issued to disk units are available. A selection condition is detected from the I/O demand information supplied by a host computer, and an optimum one of a plurality of RMW processing systems is selected and executed on the basis of the selection condition.

    摘要： A host computer is connected with a magnetic disk storage device by an SCSI bus. In the magnetic disk storage device, a plurality of partitions are set in a disk drive unit and have device identifiers (ID's) respectively allocated thereto as SCSI ID's=1, 2 and 3, which are supported by a disk controller. When the host computer has acquired the control of the SCSI bus through arbitration and has selected, for example, the partition with the device identifier SCSI ID=1, the disk controller permits the host computer to access the partition in response to the selection. Since the partitions are different in attributes, properties etc., they appear as magnetic disk storage devices that are separate from one another when viewed from the host computer. Thus, the single magnetic disk storage device can be managed as a plurality of storage devices of different nature.

    摘要： In a disk array system, data read out and data written anew are temporarily held as former data in a former data holding portion. When a write operation has occurred, a CPU searches the holding portion for write data, it generates update data from the new and former write data items, and it holds the generated update data in an update data holding portion. In addition, the CPU stores the storage address of redundant data associated with the held update data, as log data in a log data holding portion. Further, the CPU operates asynchronously with the write operation to read out the redundant data of the address of the holding portion, to calculate new redundant data from the read redundant data and the held update data, and to write the new redundant data into the address of the log data. On this occasion, a parity area and a data area are separated so as to heighten read/write processing speeds and a parity generation processing speed.

    摘要： In a computer system utilizing an array disk for an external storage device, an array controller arranged between a host computer and disk unit group has a main controller for controlling the array disk; a buffer for temporarily buffering data transferred between the host computer and the disk units; a parity data generator for generating parity data; and an interface controller for controlling interfaces connecting the host computer with the disk units. The buffer has memories for storing transfer requested data and parity data as previous data and previous parity data, respectively. The array controller also has memory management information for managing the memories.
