ABSTRACT:
Disclosed is a method and system by which a high level of network availability is provided to a storage area network. The method and system transmit data over a storage area network from a source to a destination. A first and second path are configured from the source to the destination. Additional paths between the source and destination are created by connecting a first mid-span switch on the first path to a second mid-span switch on the second path. Additionally, the same data is multicasted over two (or more) of the paths (e.g., on different wavelength channels).
