Abstract: 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.

Abstract: 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.

Abstract: A storage control device includes a processor that reads out a group write area, in which data blocks are arranged, from a storage medium and store the group write area in a buffer area. The processor releases a part of the payload area for each data block arranged in the first group write area stored in the first buffer area. The part stores invalid data. The processor performs the garbage collection by performing data refilling. The data refilling is performed by moving valid data stored in the payload to fill up a front by using the released part, and updating an offset included in a header stored in a header area at a position indicated by index information corresponding to the moved valid data without changing the position indicated by the index information corresponding to the moved valid data. The header area is included in the data block.

Abstract: 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.

Abstract: A DE-DISK-TBL in a CMT stores configuration information on a storage apparatus, and an acquisition unit acquires information on connected DEs and disk devices and stores the information in an ENCMAP. Then, a member notification unit acquires DE-Nos from the DE-DISK-TBL by using as a search key the information on the disk devices stored in the ENCMAP. A class notification unit acquires DE-Nos from the DE-DISK-TBL by using as a search key the information about the DEs stored in the ENCMAP. Then, an integration unit determines the DE-Nos of the connected DEs on the basis of the DE-Nos acquired by the member notification unit and the class notification unit. A check unit determines whether there is an incorrect cable connection on the basis of the DE-Nos determined by the integration unit.

Abstract: 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.

Abstract: This invention relates to a molding material composed of a liquid thermosetting resin composition containing styrene monomer as a cross-linking component thereof and chopped glass fiber strands which can give a large molded product having high impact strength in high productivity and a method for manufacture thereof characterized by using glass fiber strands such that the number of glass filaments used in the glass fiber strands falls in the range of 600 to 1,400 per strand, the amount of a binder deposited on the glass fibers is not less than 1.0% by weight, and the percentage of styrene monomer insoluble binder falls in the range of 40 to 90% by weight.
