When I looked into this subject I found that lanfree supports:
- vtl
- physical tape
- file devices on GPFS (a san filesystem)
- file devices via Sanergy (nfs but with data being sent over fibre
channel)
- I found a specific comment that straight NFS for sharing File devices is
not supported by IBM (doesn't mean it doesn't work)

>From what I could figure out, Sanergy works below the NFS protocol.
Sanergy slips in below the NFS protocol and routs NFS data blocks across a
fibre channel connection.

Sorry, By not supported I meant for lan-free. Every bit of documents
I've read only refer to using a physical or virtual tape library.

Not supported by what?

If you've got a DD, then the simplest way to connect it to TSM is via
files.  Some backup apps require something that looks like a library, in
which case you'd be buying the VTL license.

FWIW, if you're already in DD space, you're paying a pretty penny.  The
VTL license isn't chicken feed, I agree, but it's not a major component
of the total cost.
