Witness vCF Streched Cluster

[santunezlenovo]

Hello Guys

I need to configure 2 clusters with vCF that are independent, I need to convert them to Stretched Cluster.

The VCF of the Secondary Site is not productive, so I am going to decommission the nodes of the Secondary Site. In a tertiary site, I will install Witness, but I have a doubt about what traffic I should pass, because I have read that I should pass vSAN and Management traffic only, between both sites.

Could you confirm if it is correct that I only have to pass that traffic.

Thank you

vSAN and management traffic will be needed for your requirement.

Note that you also need to stretch a couple of VLANs between AZ1 and AZ2:

Between AZ1 and AZ2 to the Witness Site you only need connectivity for Management VLAN (AZ1) and Management VLAN (AZ2), not vSAN since WTS is being used.
