 From imapd.conf man page:

        mupdate_config: standard
             The configuration of the mupdate servers  in  the   
Cyrus  Murder.
             The "standard" config is one in which there are discreet  
frontend
             (proxy) and backend servers.  The  "unified"  config   
is  one  in
             which  a  server can be both a frontend and backend.   
The "repli-
             cated" config is one in which multiple backend servers  
all  share
             the  same mailspool, but each have their own  
"replicated" copy of
             mailboxes.db.

             Allowed values: standard, unified, replicated

I'm not sure what I'd add to this description, other than the  
assertions I've made about the relative stability of the various  
components.

What's a "normal setup"?
