  • Publication number: 20190324969
    Abstract: A storage device, connected to a computer including a processor and first memory, and executing a program, stores data processed under the program. The computer includes a protocol processing unit that accesses data in the storage device, an accelerator that includes an arithmetic unit executing a part of a process of the program, and a second memory storing data, and executes the part of the process. The first memory receives a processing request for processing data, and causes the accelerator to execute a command to process data, corresponding to the processing request for the processing request including a process to be executed by the arithmetic unit. The accelerator requests the protocol processing unit to provide target data indicated by a command received from the program, reads data from the storage device via the protocol processing unit, and stores the data in the second memory. The arithmetic unit executes the command.

  • Publication number: 20190324697
    Abstract: An image forming apparatus operates in a normal mode in a first electric power state and in a power saving mode in which more electric power is saved than in the first electric power state. The image forming apparatus includes a motion sensor, an operation section, and a controller. The controller executes a first timer process in response to receipt of the detection signal and executes a second timer process in response to receipt of the operation signal. At a time when a first period elapses indicating that the first timer process times out, the controller transitions from the normal mode to the power saving mode. At a time when a second period elapses indicating that the second timer process times out, the controller transitions from the normal mode to the power saving mode. The first period is shorter than the second period.

  • Patent number: 10452292
    Abstract: In a scale-out type storage in which multiple physical storage systems are provided collectively as a single virtual storage system, a logical path is established between the host computer and the virtual storage system so that input/output performance of the storage is not deteriorated, wherein during allocation of a volume to the virtual storage system, if a logical control unit (logical CU) establishing a logical path to a volume is unallocated, a logical CU and a volume is generated to a storage system having either a small number of allocated logical CUs or a small amount of used storage capacity. On the other hand, if there is a storage system having a logical CU already allocated thereto, a volume is generated in that storage system.
