I am not (and cannot be) near the last production cluster. So please answers for inaccuracies and the such. YMMV etc. apply Let me get this straight: 1. You have a data network bond device of two MACs, 1 IP (not the cluster VIP, node host IP) 2. You have a "management" network of ILOs and IPMIs (actually a Single point of failure for a given box) 3. You have a third network, let us say power network consisting only of Electrical Power fencing devices . each one can be a VLAN perhaps if you have access to the networking pieces. If necessary, Inter VLAN routing may be used But highly unavisable. Keep the Data and Management/power vlan very very separate. If possible physically. Have got it right?
