Re: RHAS LVS Gaps

RHAS supports failover does it not? I believe that is
what you are looking for. Piranha handles the load
balancing and cluster manager is for setting up the
failover? I have not implimented either of these
features yet myself, but this is my understanding from
the docs I have read this far.
