摘要： A storage apparatus has a plurality of hardware engines which send and receive information to and from a controller, which, on the condition of acquiring a request command from a host, determines identifying information of the request command, executes data I/O processing to the storage device according to the request command when first identifying information has been added to the request command and when second identifying information has been added to the acquired request command, transfers the request command to the hardware engine, acquires the data requested by the hardware engine from the storage device and transfers the acquired data to the hardware engine. The hardware engine acquires and analyzes an add-on command from the host and according to the request command, requests the controller to transfer the data based on the analysis result, and thereafter executes processing to the data transferred by the controller according to the add-on command.

摘要： The PLD management system includes a PLD management unit that manages the usage status of each of one or more PLDs. The PLD management unit receives a PLD usage request from a request source module which is one of a plurality of processing modules sharing each of the one or more PLDs. when the PLD management unit receives the usage request, the PLD management unit performs control to prevent two or more processing modules including the request source module from utilizing the same PLD at the same time based on a current usage status of a PLD corresponding to the usage request and content of the usage request.

摘要： A management controller controls a data buffer and a flash controller, which controls I/O of data to and from flash memories, based on a search request. A data decompression engine includes a plurality of data decompression circuits for decompressing, in parallel, the compressed data transferred from the data buffer. A data search engine includes a plurality of data search circuits for searching, in parallel, data which satisfies search conditions among the respective data that were decompressed by the data decompression circuits, and transfers, to the search request source, the data obtained in the search performed by the data search circuits, wherein the flash controller reads, in parallel, a plurality of compressed data requested in the search request, and transfers the read compressed data to the data buffer, and the management controller transfers the compressed data to the data decompression engine when the compressed data is stored in the data buffer.

摘要： A computer system according to one preferred embodiment of the present invention has a server and a storage subsystem, wherein the server is configured to enable data write to a cache area of the storage subsystem. Further, the server manages the usages of the cache area. When storing data from the server to the cache area, the server determines whether a data-writable area exists in the cache area or not. If there is a writable area, data is stored in the writable area.

摘要： A purpose is to speed up a write process with a parity update. An information processing system includes storage devices constituting a RAID group, coupled to one bus and communicating with each other. Each of the storage devices includes a device controller and a storage medium for storing data. The storage devices include a first storage device storing old data and a second storage device storing old parity associated with the old data. A first device controller of the first storage device creates intermediate parity based on the old data and new data for updating the old data and transmit the intermediate parity to the second storage device specifying the second storage device storing the old parity associated with the old data, and a second device controller of the second storage device creates new parity based on the intermediate parity and the old parity.

摘要： To be capable of efficiently transmitting appropriate information on the motion improvement to a person in motion. A motion evaluation system includes a sensor unit, an information processing device, and an information presentation device. The information processing device includes a communication device, a storage device, and an arithmetic device. The arithmetic device acquires motion data acquired by observing a user through the use of a sensor via the communication device, checks the motion data against information about the correctness of motions in the reference information, determines a state of motion of the user, specifies a motion in a state to be improved as an improvement, check the motion data after the motion corresponding to the improvement against information about busy levels of the user to specify a busy level of the user, and outputs, as improvement suggestion information about the improvement, information with different contents at each of multiple times to an information presentation device based on the improvement and a rule predetermined according to each situation of the busy level.

摘要： A storage unit includes a plurality of storage devices that form a RAID group, that are coupled to the same bus, and that communicate with each other. Each of the plurality of storage devices includes a device controller and a storage medium. The plurality of storage devices store each of data and parities generated on the basis of the data, the data and the parities being included in RAID stripes. A first device controller of a first storage device included in the RAID group transmits, to the plurality of storage devices included in the RAID group other than the first storage device, an instruction to transfer the data and/or the parities included in the RAID stripes and restores the data or the parity corresponding to the first storage device of the RAID stripes on the basis of the transferred data and the transferred parities.

摘要： A work support system is capable of avoiding situations where a worker performs erroneous work. The system includes an identification unit which identifies a target of an inquiry from a worker based on a video acquired by an imaging device, a selection unit which selects determination model information corresponding to each of one or more targets of inquiry identified by the identification unit from a storage unit storing determination model information to be used in a determination model. A determination unit determines whether each of the targets of inquiry is correct by using each of the determination models in which the determination model information, which was selected by the selection unit, corresponding to each of the one or more targets of inquiry identified by the identification unit, has been set in the determination model. An output unit outputs a determination result of the determination unit.
