I am running a lab enviornment on my laptop two node SQL 2008 R2 running on windows 2008 R2 clustered Vms
Based on my understanding
a) Public Network or all Communication network
I see checkbox is enabled for cluster communication on this network also.
b) Private or HeartBeat or Cluster communication only network.
It appears to me that currently public network is used for cluster communication?
Is this correct? Does heartbeat network is used only for redundancy and cluster communication is primarily done on public network?
