Can I deploy vCenter HA network over VXLAN?

Hi All, hope you are doing fine in this difficult times.

Just a Silly question, i'm reviewing vCenter HA and it requires a portgroup for Active/Passive/Witness heartbeating.
Do you think this can be accomplished with a VXLAN logical switch? I have googled a little bit and found noone that has done it this way.

Hi Nacho. You can. please take a look at https://blogs.vmware.com/vsphere/2018/04/vcenter-high-availability-deep-dive-part-1.html.

Also consider that if you have a problem with NSX VTEPS in the esxi that has a VCHA node, you may have some problems, but at the end it is the same problems you would have with any VM over vxlan. I think for management workloads I would go with VLAN but it always depends of the scenario

Agree that some issues can exist. 

thinking on a stretched cluster solution or something like that not all organizations have the means to extend a VLAN. In that way VXLAN is a more cost effective solution.

Hey Nacho ,

I believe we should be able to achieve this .

• Create a cluster having three hosts .
• Have 2 logical switches : one for management network ,Other one for heartbeat network
• Have interfaces configured on the DLR
• You can also have edge gateway  ,transit switch, in-case you want to keep VCSA open to internet for patching .
• Before configuring check the connectivity of the logical switches between the hosts, vmk (vtep) test
• Also check if you are able to ping from one network to the other . Connectivity on DLR part is fine
• Each VC node on each host

VTEP test  (Tried in lab)

Cheers!!
