Heartbeat network in a windows 2016 cluster

Hello,

I have many servers on a blade where all have dSwitches with VLANID for network production servers, ratification, development and DMZ and so on.

I am creating a windows 2016 cluster for sql server in this VMware environment.

How would I configure a heartbeat NIC in this scenario?

Generally when we have a VMware server and we create a cluster in it for validation, as vSwitch is on the same computer, when I create an isolated vSwitch, it works perfectly.

But as I have multiple servers in VMware clustered with DRS, I was in doubt on how to do this setup.

Or even, do I need a heartbeat NIC for a clustered sql windows?

Thank you.
