 A virtual tape library operates and connects just like a physical tape
library in a SAN environment.  The VTL, TSM server and your client are
connected to the SAN so a LANFREE back-up works using TSM's LANFREE
technology.  Since the topology is conventional you should also be able
to add a SAN Data Gateway and do a "server free backup".  The key is
that a VTL is just a conventional fiber connected library with really
fast robotics and drives. Yes, you do need to make sure that the VTL
plays nice with TSM, so make sure your choice in VTL is TSM certified.
