By LANFree, you mean LAN Free to disk?

last time I looked at it, Sanergy was NFS for UNIX hosts, and CIFS for
Windows. (So if you have both platforms in your environment, you needed
two setups.)

If you used NFS for the front-end semantics, you still had some
range-based locking for the shared disk accessed over the SAN. The
presence of the SAN disk and the Sanergy special sauce made this solution
"LAN Free".

If you're just talking about using NFS as a storage target for a storage
agent, then that is something else. Unless you're running TCP/IP over your
FC switches, that NFS traffic is going over the LAN. If the data traffic
flows over the LAN, that isn't LAN Free.

Thanks,

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.
