  If the devices only allow one IP for the RADIUS server, you can only
have one RADIUS server.

  You need to make sure the server is running.  See various HA systems
for redundancy.  But if you have less than 10K users, it's probably not
worth it.  Just monitor the system to be sure it doesn't go down.
