  • Information-storage system
    Patent number: 8429361
    Abstract: An information-storage system storing information includes, an information-storage unit configured to store data, an encoding/decoding unit configured to encode and store input data in the information-storage unit, and decode and output the encoded data stored in the information-storage unit upon receiving a request for an information output, a transmission unit configured to output the encoded data stored in the information-storage unit, the encoded data being left undecoded, and store the encoded data in a backup spot different from the information-storage unit, a status-monitoring unit configured to monitor an unusual status of the information-storage system, and a selection unit configured to select the transmission unit between the encoding/decoding unit and the transmission unit when the status-monitoring unit confirms the unusual status of the information-storage system.
    Type: Grant

  • RAID apparatus and logical device expansion method thereof
    Patent number: 7127557
    Abstract: A RAID device changes the redundancy of the RAID configuration, while allows various RAID level conversions and capacity increase. Using new and old RAID configuration definition information which define at least a RAID level and a number of logical devices, the control unit performs RLU mapping based on the respective RAID configuration definition information, and performs staging and write back to change the RAID configuration. Therefore various RAID level conversions and capacity increase can be implemented.
