We have a few 2 node NLB clusters on our network but they cause excessive network traffic due to the multicast mode. We're thinking about creating a vlan for NLB but want to keep the cluster IP / host IP on the current network. What's the best way to achieve this? If we have 2 nics in each host, could we have one in each dedicated to NLB heartbeat, doing the multicast and in a vlan, and the other 'production' nic for connectivity? Which would the virtual / cluster IP address be in?
e.g.
host1 nic1 = heartbeat vlan, multicast traffic
host2 nic1 = heartbeat vlan, multicast traffic
host1 nic2 = production vlan
host2 nic2 = production vlan
cluster ip = production vlan.
Or is there a better way to do it? It needs to be multicast due to VMware etc..
