ABSTRACT:
A media area network includes a storage system having at least one storage device for storing digitized information. A host bus adapter provides a link between the storage system and a host system that provides overall control of the media area network. Within the host bus adapter, a lower-level port driver monitors communications between the storage system and the host bus adapter. In the event of a communications failure, the lower-level port driver initiates switching from a failed port to an alternative port, thereby achieving fail-over recovery. Allocating the responsibility for fail-over recovery to the lower-level port driver assures timely handling of port failures, thereby reducing potential latency delays.
