A storage control device, includes: a memory configured to store meta information and map information, the meta information associates a logical address to identify data from an information processing device which uses a storage with a data block identifier to identify a data block used for an arrangement of the data on the storage and including a header area and a payload area and an index indicating an order of additional writing of the data, the map information associates the data block identifier with a physical identifier indicating a physical position on the storage; and a processor specifies the data block and a write position in a payload area based on the physical identifier and the index, writes the data in the specified data block and performs a write control to write a data unit header including an offset and a data length at a position designated by the index.

Storage control device using index indicating order of additional writing of data, storage control method using index indicating order of additional writing of data, and recording medium recording program using index indicating order of additional writing of data

A first control apparatus of multiple control apparatuses in a system, including a memory unit and a processor. The memory unit stores multiple management information managed by respective control apparatuses and multiple modification information indicating update statuses of respective management information. In response to receiving first modification information corresponding to first management information managed by the first control apparatus from a second control apparatus, the processor compares the received first modification information, with first modification information stored in the memory unit. When the received first modification information does not match the first modification information stored in the memory unit, the processor notifies the second control apparatus of a response including information about the first management information and the first modification information stored in the memory unit, to cause the first management information and the first modification information stored in the second control apparatus, to be updated.

Control apparatus in a plurality of control apparatuses for managing management information

A communication system includes a communication apparatus comprising a plurality of first connectors; a controlling apparatus that comprises a plurality of second connectors; a first gathering unit that gathers first identifiers for the respective communication cables coupled to the plurality of first connectors of the communication apparatus; a second gathering unit that gathers second identifiers for the respective communication cables coupled to the plurality of second connectors of the controlling apparatus; and a connection normality determining unit that determines whether or not the communication cables that connect between the controlling apparatus and the communication apparatus are connected properly, by comparing the first identifiers with the second identifiers.

Graphic data generated by an application program implementing CAD, for example, are classified into groups according to their attributes and stored into memory. When a display request is issued, the graphic data are output onto a display device, one group at a time, thereby reducing the amount of attribute judging and attribute changing processing and thus achieving an increase in the display processing speed.
