Abstract: A memory system includes a nonvolatile memory and a memory controller including a bus, a cache memory, a direct memory access controller, a first search circuit, a second search circuit, and a transfer control circuit. The direct memory access controller transfers cache target data stored in the nonvolatile memory to the cache memory. The second search circuit searches the cache target data that is being transferred. The transfer control circuit assigns, in response to the second search circuit detecting a search hit, to the transfer control circuit and the second search circuit, a bus right which has been assigned at least to the cache memory for the transfer of the cache target data to the cache memory, and obtains, by using the assigned bus right, a search result from the second search circuit via the bus.

Abstract: An object of the present invention is to provide to suppress deformation of a terminal member caused by abutting contact of the terminal member with a housing side during attachment of the terminal member to the housing. When a terminal bolt is mounted, a ground terminal rotates in conjunction with rotation of the terminal bolt. In this case, a side edge of an abutting portion, which is formed like a plate, comes into abutting contact with a side surface of a second housing. At this time, a side edge of the terminal main body, which is also formed like a plate, also comes into abutting contact with the side surface. Thus, the rotation of the ground terminal is regulated.

Abstract: Proposed is an operation method for seeking a power interruption operation target in which MTBF will become longest. When a target value regarding a power interruption time and a target value regarding a power interruption count per 24 hours is input from an administrator to a management computer, the management computer calculates the MTBF after one year and the annual power consumption for each of the input target values, and, as a power interruption operation target in which the MTBF will become longest in one year, a target value regarding a power interruption time and a target value regarding a power interruption count are respectively selected among multiple target values in which the MTBF will become longest based on each of the calculation results, and displayed on a screen of an output unit.

Abstract: When there is a change in a group of volumes managed by a host computer, data duplication processing is immediately carried out against the changed volume. The host computer includes a volume-managing portion, a data duplication-controlling portion which executes the data duplication of data stored in a volume in a main data center, and a data duplication storing portion which stores data necessary for the data duplication. The data duplication-controlling portion compares data held by the volume-managing portion with the data in the data duplication storing portion, and updates the data in the data duplication storing portion based on the data held by the volume-managing portion.

Abstract: A computer system having a plurality of operating systems and a module for switching the operating systems in view of priorities of tasks to be performed by each of the operating systems. Each of the operating systems performing a plurality of processes or threads in accordance with the priorities assigned to these processes or threads has a module for notifying the computer system of the priority of the currently executing process or thread. The computer system includes a module for translating the priorities sent from each operating system into priorities (normalized priorities) common-throughout the computer system, and a module for comparing the normalized priorities obtained by the priority translation module in order to select and execute preferentially the operating system having a common priority higher than that of any other operating system.

Abstract: A computer system of a multi-operation-system (multi-OS) has a main memory having a memory area for a first OS and a memory area for a second OS, both the areas being independent from each other, and a plurality of I/O devices divisionally allocated to the first OS and the second OS. The first OS is loaded in the first OS memory area, and thereafter when the first OS is operated, the second OS is loaded in the second OS memory area and initialized. When the first OS is operated, the first OS hardware resources and the second OS hardware resources are registered by the first OS. Thereafter when the first OS is operated, the first OS inhibits the registration of an interrupt number already allocated to the second OS I/O device. In response to an interrupt request from a second OS I/O device, the second OS starts operating.

The computer includes: an interface coupled to the network, a processor coupled to the interface and a memory coupled to the processor. The storage system includes a plurality of volumes in which files are stored. The processor is configured to: decide duplicating files from among the files stored in the plurality of volumes as files to be consolidated; identify a plurality of volumes in which the files to be consolidated are stored; select at least one volume from among the identified plurality of volumes as a consolidation volume based on loads imposed on the identified plurality of volumes; and delete the files to be consolidated stored in the volumes that are not selected. Accordingly, in data de-duplication, it is possible to avoid extra loads from centralizing in a high-load-bearing volume.

Abstract: A lock structure for a box includes a first box member having a retaining projection, and a second box member having an elastic retaining arm. The retaining arm has at its distal end a retaining portion for engagement with the retaining projection. The first box member has an arm restraint rib which restricts a releasing movement of the retaining arm in a condition in which the retaining arm and the retaining projection are engaged with each other. When the arm restraint rib is pressed by the elastic retaining arm, the arm restraint rib is deformed by a pressing force of the elastic retaining arm. A retaining distance of the retaining projection relative to the retaining portion of the elastic retaining arm is larger than a gap between the elastic retaining arm and the arm restraint rib in the engaged condition.

The host computer 10 comprises a volume-managing portion (unit) 12, a data duplication-controlling portion(unit) 11 which executes the data duplication of the data stored in the volume 32 in the main data center 3, and a data duplication storing portion (unit) 13 which stores data. necessary for the data duplication. The data duplication-controlling portion 11 compares data held by the volume-managing portion 12 and the data in the data duplication storing portion 13, and updates the data in the data duplication storing portion 13 based on the data held by the volume-managing portion 12.

Abstract: An operation site has copy management information including state information that is used when executing a remote copy. The copy management information is stored in a storage device included in each of all storage device subsystems in this computer system. The copy management information is updated every time a remote copy is executed. When the operation site fails, by use of a copy management program in another operatable site, and with reference to the copy management information stored in the storage device of the storage device subsystem in each site, the copy is executed from a point to which the copy processing has progressed before the failure. As a result, when the production site in which an application is operated suffers from a disaster, it is possible to quickly recover data at the time of the disaster by executing a disaster recovery management program from another site in which no failure occurs, and then by restarting the remote copy.
