  • Storage failure processing in a shared storage architecture
    Patent number: 10180871
    Abstract: The disclosed embodiments relate to systems and methods for coordinating management of a shared disk storage between nodes. Particularly, a messaging protocol may be used to communicate notifications regarding each node's perception of the shared storage's state. The nodes may use the messaging protocol to achieve consensus when recovering from a storage device failure. Some embodiments provide for recovery when localized failures, such as failures at an adapter on a node, occur.
    Type: Grant

  • Shared storage architecture
    Patent number: 9471259
    Abstract: A shared storage architecture is described for coordinating management of a shared storage between nodes of a network storage system. In various embodiments, the shared storage is partitioned into and different partitions are assigned to different nodes of the network storage system. The shared storage architecture provides techniques for asserting reservations on the shared storage, managing state of the shared storage, and implementing various configurations of the network storage system using the shared storage.

  • Bounding I/O service time
    Patent number: 7389396
    Abstract: A storage system with an array of redundant storage devices places bounds on access request servicing. If a storage device is unable to service the access request within the bounds, the storage system temporarily, individually offlines the specific storage device. Access requests pending for the storage device may be serviced by other storage devices of the redundant array while the storage device is offline. The offline storage device can perform error recovery and be brought back online by the system when error recovery has completed.
