  • Preserving data integrity during controller failures
    Patent number: 11593236
    Abstract: Systems and processes are disclosed to preserve data integrity during a storage controller failure. In some examples, a storage controller of an active-active controller configuration can back-up data and corresponding cache elements to allow a surviving controller to construct a correct state of a failed controller's write cache. To accomplish this, the systems and processes can implement a relative time stamp for the cache elements that allow the backed-up data to be merged on a block-by-block basis.
    Type: Grant
    Filed: May 4, 2022
    Date of Patent: February 28, 2023
    Assignee: Seagate Technology LLC
    Inventors: Adithya Uligere Narasimhamurthy, Ritvik Viswanatha, Michael Barrell
