  • Patent number: 8683122
    Abstract: A storage system includes: an identification information providing means that provides identification information distinguishing a group of data requested to be stored, to the group of data; a data set generating means that divides storage target data as part of the group of data into multiple pieces and makes the data redundant, thereby generating a data set composed of multiple fragment data; and a distribution storage controlling means that distributes the fragment data composing the data set and store the fragment data, respectively, in same positions within storage regions formed in the respective storing means, thereby storing the storage target data. The distribution storage controlling means stores the fragment data composing respective data sets corresponding to multiple storage target data included in the group of data provided with the same identification information, into the respective storage regions so that storing positions within the respective storage regions become successive.

  • Patent number: 8683121
    Abstract: A storage system includes: a plurality of storing means and a data processing means that stores data into the plurality of storing means and retrieves the data stored in the storing means. The data processing means includes: a data set generating means that generates division data by dividing storage target data into a plurality of pieces and also generates redundant data for restoring the storage target data, thereby generating a data set composed of a plurality of fragment data that are the division data and the redundant data; and a distribution storage controlling means that distributes and stores the fragment data into the respective storing means. The distribution storage controlling means stores the fragment data composing the data set in same positions within storage regions formed in the respective storing means, respectively.

  • Publication number: 20110271050
    Abstract: A storage system includes: a plurality of storing means and a data processing means that stores data into the plurality of storing means and retrieves the data stored in the storing means. The data processing means includes: a data set generating means that generates division data by dividing storage target data into a plurality of pieces and also generates redundant data for restoring the storage target data, thereby generating a data set composed of a plurality of fragment data that are the division data and the redundant data; and a distribution storage controlling means that distributes and stores the fragment data into the respective storing means. The distribution storage controlling means stores the fragment data composing the data set in same positions within storage regions formed in the respective storing means, respectively.
