Chris,

I try to explain to my customers in the following order:
1. Normal behavior (LAN) is in three steps - Node storage -> TSM Client ->
TSM Server -> Tape
2. LAN-free transfer reduces them to two steps eliminating one by
combining last two in one - Node storage -> TSM Client/Storage agent ->
Tape (last step requires SAN-shared tape)
3. server-free eliminates one more step, skipping both TSM server (as in
LAN-free) and TSM client (new add-on) - Node storage -> SAN-tape
The last "single-step" is accomplished using SAN data mover, i.e. device
on SAN capable to perform data transfer between a disk (Node storage) and
tape (TSM server storage) without any host involvement (neither server nor
client).
Currently supported data movers are IBM SAN Data Gateway (2108-G07 and
same module in IBM 3583) and Pathlight 5000.
Hope this helps to you to understand. This will prove my "customer"
explanation :-)

Hi All

Can someone please explain the difference between serverfree and lanfree
backup?

My understanding is that LAN free still involves the clients they just
send
their data over the SAN, and Serverfree uses some method to backup without
involving the client.

What software/clients/agents do you need to achieve both of these
solutions?

Working on a big implementation at the moment, including win2000, HSM,
2000
clusters, Exchange clusters new SAN, new storage etc etc etc.  I think you
going to be hearing a lot from me over the next couple of months, ! !!
