  • Redundant multi-processor and logical processor configuration for a file server
    Patent number: 7028218
    Abstract: A redundant file server includes at least two dual processor boards. Each physical processor has two logical processors. The first logical processor of the first physical processor of each board executes storage system code under the Microsoft NT™ operating system. The second logical processor of the first physical processor of each board executes control station code under the Linux operating system. The first logical processor of the second physical processor of each board executes data mover code. The second logical processor of the second physical processor of each board is kept in a stand-by mode for assuming data mover functions upon failure of the first logical processor of the second physical processor on the first or second board.
