Abstract
A storage router having an internet protocol (IP) port for coupling to a network supporting IP packets, a fibre channel port for coupling to a fibre channel network to a plurality of storage devices, and a SCSI router having an iSCSI interface that extracts SCSI command and data information from packets received through the IP port, wherein the SCSI router passes the extracted SCSI command and data information to the fiber channel port. Some embodiments further include a session to an information-handling system. The session supports a target-only mapping (wherein a source-specified target value is replaced by a mapped target value that is then passed by the SCSI router toward a first storage device and its LUNs), or target-and-LUN mapping (wherein source-specified target and LUN information is replaced by mapped target-and LUN information such as a loop-ID and LUN combination, a WWPN and LUN combination, or a WWNN).
