Idea is that they share same mails/rules and acti simultaneously. A
loadbalancer will stand in front of those boxes.

Sure if
a) You want the SAN to just be a disk store and CB1 and CB2
have
independent stores. The benefit of the SAN would be that you can add
additional partitions to CB1 and CB2 as the needs of each store increases.
b) Your SAN software provides Unix locking semantics between
CB1/CB2 then
you can have them both running.
c) Your SAN software provides heartbeat and/or other failover
support then
you can have CB1 fail over to CB2.

The botton of <http://asg.web.cmu.edu/cyrus/imapd/license.html> gives you
an address to send the reward for providing the base IMAP server. :-) We
may "soon" be able to accept credit cards too.
