  • Failure detection and failure handling in cluster controller networks
    Patent number: 6934878
    Abstract: A cluster network may manage the detection and handling of failures in a cluster of RAID arrays by detecting failures and reconfiguring the cluster. A storage controller may interrogate its neighboring controller to determine if the neighboring controller is active.
    Type: Grant
    Filed: March 22, 2002
    Date of Patent: August 23, 2005
    Assignee: Intel Corporation

  • Distributing access rights to mass storage
    Publication number: 20030188096
    Abstract: A cluster network may manage access to a RAID array by allowing only one controller of a group of controllers to access the same array at the same time. Tokens may be assigned for access to a given array by an appointed master controller. All other controllers requesting access to the array must request a token from the master. After the token has been assigned, the master may request the assigned token user to yield its access to the array in favor of another request.

  • Implementing clustering in raid controllers
    Publication number: 20030182479
    Abstract: A cluster network may manage access to a RAID array by allowing only one controller of a group of controllers to access the same array at the same time. Tokens may be assigned for access to a given array by an appointed master controller. All other controllers requesting access to the array must request a token from the master. After the token has been assigned, the master may request the assigned token user to yield its access to the array in favor of another request. To detect network errors, each controller may monitor one or more neighboring controllers.
