  • Ensuring data integrity on a dispersed storage grid
    Patent number: 9996413
    Abstract: An improved system is disclosed for ensuring the integrity of data stored on a dispersed data storage network. Checksums are used to ensure integrity of both data segments and data slices. Checksums appended to data slices are checked by receiving slice servers to ensure that no errors occurred during transmission. Slice servers also periodically recalculate checksums for stored data slices to ensure that data slices have not been corrupted during storage. Checksums appended to data segments are checked when data segments are read from the storage network.
    Type: Grant
    Filed: October 9, 2007
    Date of Patent: June 12, 2018
    Assignee: International Business Machines Corporation
    Inventors: Greg Dhuse, Vance Thornton, Jason Resch, Ilya Volvovski, Dusty Hendrickson, John Quigley
  • Systems, apparatus, and methods for utilizing a reachability set to manage a network upgrade
    Patent number: 9092294
    Abstract: A method of upgrading software components within a dispersed data storage network is disclosed. A list of identifiers corresponding to devices within the dispersed data storage network is assembled. Each member of the list is assigned to an upgrade set based on the devices that are reachable by the vaults associated with the device.

  • Rebuilding data on a dispersed storage network
    Patent number: 8880799
    Abstract: A rebuilder application operates on a dispersed data storage grid and rebuilds stored data segments that have been compromised in some manner. The rebuilder application actively scans for compromised data segments, and is also notified during partially failed writes to the dispersed data storage network, and during reads from the dispersed data storage network when a data slice is detected that is compromised. Records are created for compromised data segments, and put into a rebuild list, which the rebuilder application processes.
