An information processing device, for an information processing system including a plurality of information processing devices, executes a process causing a processor of the information device to: classify the plurality of information processing devices into a plurality of device groups each including a given number of information processing devices; select information processing devices one by one from each of the plurality of device groups based on a given selection condition; assign the selected information processing devices to a first update group; and transmit, to first information processing devices each of which is any of the plurality of information processing devices and belongs to the first update group, an instruction to update software applied to the first information processing devices.

Information processing device, information processing system, and control method

A storage control apparatus controls a storage device. The storage device includes a first storage area and a second storage area different from the first storage area. An error detection information storage unit generates an ECC for each of data blocks in data to be written, as error detection information. The error detection information storage unit stores generated ECCto ECCin the first storage area. A data storage unit stores data blocks DBto DBin the second storage area. A detection unit performs error detection on each of the data blocks according to the error detection information read from the first storage area and the data to be written read from the second storage area.
