  • Storage system
    Patent number: 9201891
    Abstract: Duplicate storage elimination is performed in units of block data generated by dividing a data stream into arbitrary-sized blocks. Further, sub-block data is generated by further dividing the block data into a plurality of pieces of data, and sub-address data based on the data content of each of the pieces of sub-block data is stored in a predetermined storage device. As such, duplicate storage elimination is also performed in sub-block data units based on the sub-address data.
    Type: Grant
    Filed: August 25, 2011
    Date of Patent: December 1, 2015
    Assignee: NEC CORPORATION
    Inventors: Bartlomiej Romanski, Lukasz Heldt, Wojciech Kilian, Krzysztof Lichota, Cezary Dubnicki
  • Controlling throughput of processing units associated with different load types in storage system
    Patent number: 9182923
    Abstract: The storage system includes a progress status detection unit that detects respective progress statuses representing proportions of the amounts of processing performed by respective processing units to the amount of processing performed by the entire storage system, each of the processing units being implemented in the storage system and performing a predetermined task; a target value setting unit that sets target values of processing states of the processing units, based on the detected progress statuses of the respective processing units and ideal values of the progress statuses which are preset for the respective processing units; and a processing operation controlling unit that controls the processing states of the processing units such that the processing states of the processing units meet the set target values.
