Packeteer's IShared appliance is suited for CIFS over the WAN. You put a
server appliance in the "datacenter" and a remote appliance in the branch
office. The appliance runs windows and to the users in the branch it looks
like a windows file server. The shares the users see are a real-time
window
into the datacenter file servers. There is an optimized tunnel that runs
between the datacenter and branch appliances, that does streaming and
compression and file aware differencing. So as users access files they see
on
the remote they get optimized accross the WAN then stored on a cached
volume
on the remote. The datacenter appliance places a lock on the original file
on
the file server while the user in the branch has it open. If a user makes
a
100k change to a 3 meg word file, only the changes get sent across the wan
and the original gets updated. The next access to that same file will be
served up from local cache and the software will first checkk the
datacenter
and see if the cached copy is the locked and if it's the latest rev. If
it's
not locked and the original has changed..it'll send the deltas to the
branch
and serve it up to the user. It's cool cause you can forget about file
servers and the hassles of backups in the branch. The authoritative copy
is
always on the datacenter file servers. It's truely "tight collaboration"
unlike R2's "loose collaboration". Another cool thing is since that the
appliance runs windows it can be a DC, DNS, DHCP and Print server all in
one
footprint. Yet another cool thing is that they sell software..which is
what
we bought...so I've deployed the WAFS solution on DELL 1850's instead of
an
appliance.
Thanks -- that is interesting.
Sorry for the long winded responce...hope this helps...any more questions
let me know...I'd be happy to answer.
Never need to apologize for a complete response since
that is both how we learn AND anyone who doesn't care
can just hit next or delete.
So (as I understand it) it looks and acts like DFS BUT it
is much more optimized for file transfer and file locking,
i.e., not dependent on the built-in FRS for the replication?

No problems with the appliance do you have any questions about it? I've
deployed many.

Thanks for the reply. I understand the auth and dns issues. Trying
to
deploy
a Tacit Networks/Packeteer IShared WAFS appliance in a remote site
and
want
it to be the link target for the dfs namespace but we might not be
able
to
put DC's in all sites. Was hoping that it wasn't a technical
requirement..Thanks to all who replied.

Quick question about DFS site selection...
Can you create a site in AD, add subnets, links..etc but not have
a
domain
controller in the site and have DFS site selection work? Trying
to
figure
out
if a DC is a requirement...
No, not a technical requirement but consider that if DFS
is a domain resource and access to that resource is critical
then DOMAIN AUTHENTICATION is also critical.
Chances are this will argue for a DC and a DNS server in
that site but you already have at least one server (the DFS)
so it might not even cost you a machine.
And you authentication will be more efficient too.
Any info appreciated...thanks,
