  • Session-based target/LUN mapping for a storage area network and associated method
    Patent number: 7506073
    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).

  • SCSI-based storage area network having a SCSI router that routes traffic between SCSI and IP networks
    Patent number: 7437477
    Abstract: A system and method for accessing Storage Area Networks over an IP network. A SCSI request is generated and encapsulated in one or more IP packets. The encapsulated SCSI request is routed over an IP network and received by a storage router. The storage router extracts the SCSI request from the one or more IP packets and routes the extracted SCSI request through a virtual SCSI router to the storage area network.
