I'm not sure if it is a good thing to have physical serves, although we have a vmware cluster in both nodes which has enough capacity (ram, cpu, disk)? I once read that the vmware boxes have a performance issue with heavy udp based services. Did anyone of you face such an issue? Are your dns servers all running on physical or virtual boxes?
where did you read that?we don't run *anything* on physical machines and all our nameservers (auth, caching with a mix of bind/unbound/rbldnsd) as anything else runs on top of VMware vSphere 5.5, previously 4.1/5.0 since 2008
there is zero to no justification these days for run anything on bare metal when you read artciles like https://blogs.vmware.com/vsphere/2015/03/virtualized-big-data-faster-bare-metal.html
