Abstract:
PROBLEM TO BE SOLVED: To provide a GUI-based display device for displaying contents of a currently set screen when a series of screen indications transits between a setting screen displayed in the past (past set screen) and a currently displayed screen (currently set screen) for the same screen.SOLUTION: A business management system includes: means for recording numbers and stay display times of a series of multiple setting screens to be transiently displayed; means for allocating a forgetting degree of a current screen as a transition from other setting screens displayed in a transition process from a past set screen to a current screen; means for evaluating a total forgetting degree of the current screen while considering all the forgetting degrees transiting from the other setting screens displayed in the transition process; means for determining a forgetting threshold value based on an importance degree of a job for each screen; means for comparing the total forgetting degree with the forgetting threshold value; and means for emphasizing and displaying overall screen contents (e.g., caution display) or a differential in the case where the total forgetting degree is smaller than the forgetting threshold value.
Abstract:
PROBLEM TO BE SOLVED: To achieve the use efficiency of a plurality of storages as a whole in the case of storing data in those storages.SOLUTION: In a storage node 20, a meta data extraction part 21 is configured to extract meta data from storage object data from a client 10, and a node determination part 24 is configured to, on the basis of the capacity information of each storage node stored in a capacity information storage part 22 and summary data obtained by integrating the meta data of the storage data of each storage node stored in a summary data storage part 23, determine a storage node in which the storage object data should be stored, and a data transfer part 25 is configured to, when the determined storage node is a self-node, store the storage object data in a data storage part 27, and a summary data registration part 26 is configured to register the extracted meta data in the summary data of the self-node, and the data transfer part 25 is configured to, when the determined storage node is another node, transfer the storage object data to the node.
Abstract:
PROBLEM TO BE SOLVED: To perform access not lowering a performance specialized in sequential media without executing mounting depending on a hardware device on an application side.SOLUTION: In a file system 60, a command processing part 61 takes out an option indicating a file listing method from a command, an index reception part 63 receives an index including a directory name, a file name and a recording position from a tape drive, and an index storage part 66 stores the index in the state as it is or in the state of changing the directory name or the file name according to the listing method indicated by the option. In the meantime, when an IRP reception part 67 receives an IRP (I/O Request Packet) from an OS, an IRP setting part 68 stores the file name inside the index in a buffer of the IRP in the order of the recording position, and a response transmission part 69 returns a status to the OS.
Abstract:
PROBLEM TO BE SOLVED: To provide a technology for optimally relocating a file from the viewpoint of power-saving. SOLUTION: This file relocation device is connected to a plurality of storage devices, for each of a plurality of files stored in the plurality of storage device, refers to history information of access requests to each file, and acquires the file and the number of access requests at the same time for each of all the files. Then, the relocation device divides the plurality of files into a plurality of groups by grouping the files frequently accessed at the same time. A plurality of files in one group are relocated in the same storage device. Then, the relocation device shifts a storage device having not accessed for a predetermined time to a power-saving mode.
