Ok so I started to attempt to create a 3 server 2 client setup. I
thought I would use 3 servers and i would only want 2 copies of files.
I thought to do this you needed afr + unify.

However, AFR uses the number of servers as the number of copies, so
even using 3 servers I dont see a reason to use unify? Wont it just
send every write to all 3 servers anyway? So what is unify doing in
the example?

Is that just a bad example that I am trying to follow?
