according this example / poc the witness host's vmk0 is reachable over l3.
Do i run in problems if i connect the vmk0 over l2 in the same subnet like the vcenter and the vmk0's of the vsan hosts? For witness traffic i want to use the dedicated vmk1 on the witness host which connects via l3 to dedicated vmk's on the data nodes.
Thanks & Regards
Do you mean that all "three" sites will be on the same L2 for vmk0 (mgmt)? That's not a problem.
