Abstract

The present invention provides a method and system for mapping addressing of SCSI devices (170, 180) between two SANs (110, 112, 115) connected by a SAN extender over a packet-based network with use of a Fibre channel protocol over large distances. The present invention seamlessly interconnects graphically distinct SANs (110, 112, 115) such that they operate as if they were local to one another by providing a means to generically and dynamically map SCSI device addresses between two SANs (110, 112, 115). The present invention provides a method and system for accessing a device (170, 180) from a host (110, 112, 115), wherein the host (110, 112, 115) and device (170, 180) are in layer and each of said SANs (110, 112, 115) is a node (120, 130, 150). This method comprises at each node (120, 130, 150) the steps of: mapping the device address into an intermediary device identifier, and mapping the intermediary device identifier into an address accessible by the host (110, 112, 115). Each node (120, 130, 150) can be a Fibre channel-to-SCSI router, and the intermediary device can comprise a node identifier and a generic device identifier. The transport layer can be a packet-based network.
