Chris,
At University of Tennessee we have located our controllers in our two
main
data centers (with UPS and generators) where our network core devices
are located. No controllers are located
in regular buildings. We have a n+1 architecture between the two cores
and also two redundant Master controllers.
Each controller is connected to the core of the network with 10 GigE.
Anything between n+1 and n+n will give you a level of redundancy. Your
wallet is the limit!
In our case we have decided that if a whole core location goes down
(granted that each location has a lot of redundancy and it would
have to be catastrophic to completely fail), we will have bigger
problems than worry about wireless!

I work for a University that is starting to rely on the wireless
more and more. I am currently using the meru wireless system with
the Nplus1 technology. This works great as long as you don’t have
more than one controller go down at a time, but if you would lose a
whole building or more than one controller there will be an outage.
I was wondering what other universities are doing to get true
redundancy? Are you buying a nplus1 controller for every production
controller?
Thanks in advance,
