  • Volume duplication
    Patent number: 9870287
    Abstract: A method, computer program product, and computing system for receiving a point-in-time copy command for a virtual volume exposed within a storage virtualization layer of a storage system. The point-in-time copy command is provided to one or more data arrays underlying the storage virtualization layer. The virtual volume is associated with physical storage within the one or more data arrays, thus defining associated physical storage. A level of high-availability is identified for the associated physical storage. A copy of the associated physical storage is generated that has the same level of high-availability, thus defining a high-availability copy.

  • Data processing system using cache-aware multipath distribution of storage commands among caching storage controllers
    Patent number: 8627015
    Abstract: A data processing system includes a storage system and caching storage controllers coupled to the storage system and to a storage network. The storage controllers operate in an active-active fashion to provide access to volumes of the storage system from any of the storage controllers in response to storage commands from the storage network. The storage controllers employ a distributed cache protocol in which (a) each volume is divided into successive chunks of contiguous blocks, and (b) either chunk ownership may be dynamically transferred among the storage controllers in response to the storage commands, or storage commands sent to a non-owning controller may be forwarded to the owning controller.
