what's your time line? replication at application level would be best,
but the 2.3 series is quite young.
we have an old installation, so we're using LVS (2 directors in
active/active) in front of Perdition (2 frontends) in front of 16 Cyrus
instances running on three nodes sharing a SAN. the cluster software
handling the three nodes is HP ServiceGuard.
these days, Murder is the way to go, IMHO. but I don't have production
experience with it myself.
