  • Publication number: 20150012716
    Abstract: A data management apparatus has a first storage unit, a first selecting unit, a second selecting unit, and a second storage unit. The first storage unit stores data associated with first identification information. When writing data out to a storage medium, the first selecting unit selects a first storage medium on which the first identification information corresponding to the data to be written out is displayed, from among a plurality of storage media. When the first storage medium is not available, the second selecting unit selects a second storage medium attached with a display unit configured to display stored information, from among the plurality of storage media, and stores the first identification information in the display unit of the second storage medium.

  • Publication number: 20140281796
    Abstract: A processor generates a parity from dummy data attached to a first piece of data of a plurality of pieces of data and a piece of data other than the first piece of data when writing the plurality of pieces of data into a first storage apparatus. Then, the processor stores the parity in a second storage apparatus. The processor performs a reading-out process in parallel with a restoration process when reading out the plurality of pieces of data from the first storage apparatus and writing them into the second storage apparatus. The reading-out process is a process to read out the first piece of data from the first storage apparatus and to write it into the second storage apparatus, and the restoration process is a process to restore a second piece of data among the plurality of pieces of data by using the dummy data and the parity.

  • Publication number: 20130246886
    Abstract: A storage control apparatus writes n pieces of data (here, n is an integer greater than 1) in a first memory apparatus, and reads the n pieces of written data from the first memory apparatus. A parity calculation unit calculates parity based on divided data extracted from each of the n pieces of data for each certain size, and stores the calculated parity in a second memory apparatus. A read control unit restores, in reading the n pieces of data from the first memory apparatus, at least one of the n pieces of data instead of reading it from the first memory apparatus but using other data having been read from the first memory apparatus among the n pieces of data and the parity stored in the second memory apparatus.

  • Patent number: 8516206
    Abstract: A generation section periodically generates access frequency information for identifying an access frequency of each data item according to a status of write access of the data item transmitted from a host device to a storage device. Whenever access frequency information is generated by the generation section, a determination section determines whether to write data saved in a hard disk into the storage medium, or to hold a saved state of the data. A write section writes data into the storage device according to determination by the determination section.
