  • Multi-controller write operations
    Patent number: 7478215
    Abstract: A system and method for high performance multi-controller processing is disclosed. Independent Network storage controllers (NSCs) are connected by a high-speed data link. The NSCs control a plurality of storage devices. connected by a Fiber Channel Arbitrated Loop (FCAL). To provide redundancy, for a given logical unit of storage one NSC will function as the primary controller and the other NSC will function as the primary controller and the enhance the efficiency of command-response data transfers between NSCs, mirror memory is correlated with primary memory and named resources are used for command-response data transfers. Methods are disclosed to provide for efficient active mirroring of data.
    Type: Grant
    Filed: April 18, 2005
    Date of Patent: January 13, 2009
    Assignee: Hewlett-Packard Development Company, L.P.
    Inventors: Clark E. Lubbers, R. Brian Schow, Wayne Umland, Randy L. Roberson, Robert G. Bean
