I think I already know the answer to this one (No), but thought of taking your opinions. Suppose a shop wants to use different clusters for different purposes - RAC, RHCS, ServiceGuard, HACMP, Veritas and even VMware vSphere. For interconnects, they plan to have one dedicated private VLAN that will be isolated from public traffic. My question is - can the same private VLAN be used for RAC interconnects as well as other cluster interconnects? They will be having only one cluster of each type. If the answer is No, I suppose each cluster type will need a separate VLAN? For example - RAC private VLAN RHCS private VLAN HACMP private VLAN and so on. Thanks in advance!
