Abstract
A system and method for providing redundant access paths to a storage device make use of a processor to analyze instructions received from hosts to allow for command queuing, host switching, and command replacement where necessary. The system allows for either Serially Attached SCSI or Serial ATA hard drives to be connected to the same topology and to require no host intervention on the coordination of drive access in a multi-host environment. A single ported SATA device can then appear multi-ported and can support a redundant architecture within a SAS topology.
