摘要： A disk array device selects a redundant generation method for reducing the overhead and improving the reliability associated with generating redundant data. The disk array device includes a disk controller connected to and controlling an array of disk drives. The disk controller includes a redundant data generator, a difference data generator, and a redundant data generation method selector. The redundant data generator is able to generate redundant data via a read and modify method and an all stripes method. The disk array device selects a method of generating redundant data from a method of read and modify and all stripes, and a method of generation in a drive and a method of difference, both of which are executed to generate redundant data on a disk drive. The disk array device selects the method of generating redundant data that will minimize the time required to process, transfer and store both the received host data and the generated redundant data based on the length of write data received from the host, an access pattern specified by the host, by the current load state of the disk drives, and by the existence of a failure state in a disk drive. Divided write data and previous data to be updated may be transferred depending on the write data length.

摘要： Two data centers located in the vicinity are connected using a synchronous transfer copy function, and one of the data centers is coupled with a third data center disposed at a remote location by an asynchronous remote copying function. The order whereat a storage sub-system located in the vicinity has received data from a host is consistently guaranteed, and the third data center holds the data. Further, each storage sub-system includes a function whereby, during normal operation, data can be exchanged and the data update state can be obtained by the storage sub-systems located in the two data centers that do not directly engage in data transmission.

摘要： A data transfer control system in a data transfer apparatus including a plurality of data processing units having different data transfer speeds and a temporary holding circuit provided between the data processing units for temporarily holding data transferred between the data processing units. The data transfer apparatus sends a transfer request for data corresponding to a data storage capacity of the temporary holding circuit of the data transfer apparatus to the data processing unit on the side of sending data and sends a transfer request for data corresponding to the data storage capacity of the temporary holding circuit after an elapse of a delivering time of data to an information processing unit on the data transferred side of the temporary holding circuit from the time of the data transfer request is sent until the requested data from the data processing unit on the data sending side reaches the temporary holding circuit of the data transfer apparatus.
