Hi, What's a 'power fencing device'? Can we set up a cluster between 2 RHES (Ver 5.1) just by using one additional network port on each server or do we need 2 network ports per server (as hearbeat link?). Can Remote Supervisor ADapter II be used for clustering? Any specific info for setting up clustering on IBM hardware x3850 M2 & x3950 M2 is appreciated.
