    Abstract: PROBLEM TO BE SOLVED: To provide a storage device which reduces the load of processing for detecting a mistake in writing while maintaining high reliability.SOLUTION: A generation code storage part 122 stores a generation code indicative of an update state of block data associatively with identification information on the block data. A generation code management part 13 stores generation codes in the generation code storage part 122 while allocating a new generation code to detected successive data and new generation codes to respective block data other than the successive data included in write data. A data write part 15 adds the new generation codes to the block data and successive data and writes them to a storage device 19. A determination part 17 determines whether the generation code added to read-out block data or successive data matches the read-out generation code stored in the generation code storage part 122. A data transmission part 18 transmits the read-out block data or successive data when the generation code match each other.

    Abstract: PROBLEM TO BE SOLVED: To provide a data processing technology for a disk array device capable of realizing data duplication for improvement in device performance while reducing writing processing to a cache memory (via a switch). SOLUTION: In this disk array device, a host interface part 11 is provided with a non-volatile memory part 22 storing writing data from a host computer/server 1 and a data transfer control part 21 transferring writing data from the host computer/server 1 to the non-volatile memory part 22 and a global cache memory part 14. In receipt of a writing request from the host computer/server 1, the writing data are transferred by the data transfer control part 21 from the host computer/server 1 to the non-volatile memory part 22 and the global chace memory part 14 via a switch part 15 to be written.

    Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for constructing and executing a complicated software. SOLUTION: In a step S1200, input data are provided to one or plural defined storage positions. Next in a step S1300, it is determined which action of a dependent action system is to be made 'available'. When there is any action made available, control is moved to a step S1400. In the other case, control is jumped to a step S1500. In the step S1400, any one of available actions is executed.
