  • Patent number: 10824425
    Abstract: A storage system includes a management processor and main processors. Each of the main processors is configured to alternately switch between a period in which main function processing, including I/O processing in response to an I/O request from a host, is executed and a period in which a management instruction is executed. The management processor is configured to: manage information associating each of uncompleted management instructions, which are already transmitted to the main processors, with a transmission destination main processor to which the each of the uncompleted management instructions is transmitted; select, based on the uncompleted management instructions of the main processors, a transmission destination main processor to which a next management instruction is to be transmitted, from among the main processors; and transmit the next management instruction to the selected transmission destination main processor.

  • Publication number: 20190149423
    Abstract: The storage apparatus includes a control unit that manages a storage area allocated to the host computer. The control unit assigns an identifier to the host computer that accesses the storage area, and assigns the identifier to the first computer's first interface that accesses the storage area, assigns a second port identifier of a second interface of a storage device that communicates with a host computer to a first port identifier of the first interface by accepting a port identifier and sets a logical path, storing the port identifier and the second port identifier in association with each other in the host computer connection information, assigning the identifier of the storage area to the identifier of the host computer, associating the identifier of the storage computer with the identifier of the host computer, and storing the storage area allocation information.

  • Patent number: 7609320
    Abstract: An image pickup apparatus for performing dynamic assignment of an output image in a dynamic range according to a subject. An image pickup device picks up an image of a subject, a signal processing section generates a composite image having a relatively wider dynamic range than at least either of the dynamic ranges of a long-time exposure image picked up with a relatively long exposure time by the image pickup device and a short-time exposure image picked up with a relatively short exposure time by the image pickup device, by synthesizing the long-time exposure image and the short-time exposure image A, control section compresses the composite image and dynamically varies the assignment proportion of a high luminance dynamic range to a low-middle luminance dynamic range in a dynamic range of an output image to be outputted as a video signal.
