Heartbeat in Windows Server 2016 Failover Clustering

    Discuţie generală

  • Hi,

    Good day! :)

    I'm trying to figure out the importance of private network in windows clustering. From what I've searched, private network is for heartbeat. Is it necessary to have dedicated link for heartbeat?

    I have already set up windows clustering with 2 nodes. I have public and private network. I assume private network is for the heartbeat. In my testing I remove private and public network link connection of node 1 and as a result, service failover to node 2 without any problem. And then I reconnect only the public network connection of node 1. Then I remove the public network connection of node 2 and service failover to node 1 without any issues (private network still not connected).

    I tried to get traces using windump and I noticed that public network also has heartbeat packets. Does that mean that WSFC is possible even without private network dedicated for heartbeat?

    I hope you could help me with this.

    Thank you.
