in general, 'heartbeat'.     RHCS (Red Hat Cluster Service) is some 
wrappers around heartbeat, and rather a finicky control panel for it all.

you'll need sharable storage (SAN, dualport SCSI, etc), or drbd 
replication, or similar for any disk resources that need to be accessed 
by either side of the failover cluster.
