Abstract

A secondary host on a server area network (SAN) replicates files utilized and/or managed by a primary host by direct transfer of the files over the SAN to achieve substantially network free file replication. The secondary host may receive SAN relative mapping information from the primary host system, and may retrieve files identified by the SAN relative mapping information. The secondary host may also generate local mapping information from the SAN relative mapping information, and may store the files on a second set of storage elements of the SAN in accordance with the local mapping information. The SAN relative mapping information may be received over an external network from the primary host system. The SAN relative mapping information may physically identify actual storage elements and may include, for example, a vendor ID, a product ID and/or a device serial number.
