  • Publication number: 20230244385
    Abstract: A processor is configured to, when writing of first data for a first storage device is requested during update of firmware of the first storage device, write the first data for a second storage device, and register a write destination address of the first data in management information in association with the first data, and when reading of second data from the first storage device is requested during the update of the firmware, refer to the management information, read the second data from the second storage device in a case where a read source address of the second data is registered in the management information, and acquire the second data based on data stored in another storage device other than the first storage device in a case where the read source address of the second data is not registered in the management information.

  • Patent number: 10346073
    Abstract: A storage control apparatus includes a memory and a processor. The memory stores selection condition information relating to a selection condition for storage devices to construct a RAID, group information relating to groups to which the storage devices belong, and connection information indicating a connection configuration of the storage devices. The processor is configured to perform a procedure including: selecting the storage devices that match the selection condition information; extracting groups to which the selected storage devices belong based on the group information; assigning group priorities, which indicate selection priorities in units of the groups of the storage devices, to the extracted groups based on the connection information; and selecting one storage device from each of the extracted groups in accordance with the group priorities until a predetermined number of storage devices have been selected.

  • Publication number: 20190065369
    Abstract: An information processing apparatus includes a memory, and a processor coupled to the memory and configured to set, in the memory, a first region having a first capacity, receive a first request which requests to change the first region to a second region having a second capacity greater than the first capacity, set, in the memory, the second region and a reserved region in response to the first request, and cancel a setting of the reserved region when a second request which requests to change the second region to a third region having a third capacity greater than the second capacity is not received within a first time period after the first request is received.

  • Patent number: 6999631
    Abstract: An image processing technique for generating a multi-valued image with fine contours from an input image that is generated by reading, as a multi-valued image, the dotted print contents of printed matter. An image processing apparatus of the present invention generates a contour extracted image by performing the contour extraction process for the input image, and deletes contours from the contour extracted image that satisfy a predetermined condition to generate a partial contour image. Then, the apparatus adds contours to the partial image according to the density distribution of the contour in the partial contour image, and generates a contour added image. By referring to the contour added image, the apparatus superimposes the input image and a smoothed image obtained by performing a smoothing process for the input image to generate a synthesized image.
