This depends on what you mean by "some failover protection".  (Also what
you mean by "3 servers"  -- 3 frontends, 3 backends, etc?)

It makes the failure of some part of the system more likely (more pieces
make things more likely to break).  However, in the event of a failure,
you will only loose a portion of the system (provided, of course, you
don't mean 1 frontend, 1 backend, and 1 mupdate server).
