Thanks for the reply.  I wondered if it was possible to have HA for 
stateful applications.  At least
I know my options better now.  I can tolerate brief downtime, like the 
time it would take a failover
node to take over, although no downtime would have been preferred.

Any suggestions on HA solutions for a non-SAN deployment?

Thanks,
Stephen
