We are in the process of doing this. We have 2 servers in one county
and 2 servers in another. We have our data stored on a 3rd server. We
have a server in our second county. There is an additional dedicated T1
between the 2 counties. Every hour, the data on our data server is
copied to the server in the other county. If something happens at our
primary location, we simply promote the secondary data server and turn
the logins on, on our 2 spare Citrix servers. We don't have both sets
of Citrix servers running at the same time, because on pair of servers
sends data to the primary data server and the secondary pair of Citrix
servers send data to the secondary data server. We are looking at
having about 1 hour of down time, if the entire county falls off the
map. This is not exactly what the original post was asking, but I think
it may help some with their DR plans.

I might be misunderstanding.. but if you have one farm, two sites, and
(let's say) 10 servers. You could create two zones in MF with fives
servers in each zone (zone = site). This way you could manage all of
your servers from one CMC. From here you should only need to setup load
balancing. If one zone of servers is not available, any user connecting
will get their new session initiated with the servers that can be
contacted (assuming same apps are published).
This would have to be well thought out. Many questions would come to
mind: Where would your profiles and home dirs be stored? If one site
or the other goes down would your published apps still run? Where's the
production data, would it still be accessible?
Just to get you thinking...

Since hurricane season is on us again, management is looking at
disaster
recovery. Is anyone operating one farm, at two different sites,
transparent
to the user? When a user clicks to connect to the published desktop,
they
can hit either location and not know the difference. Or, some other
configuration that is totally transparent to the user, but happens
behind
the scenes in case of failure?
