Hey everyone, sorry for the nooby questions!
We have the need to deploy vDSs. We have a couple of hosts on one site and a couple on another, with multiple 10gb ports between physical sites, including aggeregation. We've deployed two clusters and 2x10gb nics dedicated to VM workloads. We have some VLANs in common between the two sites (vMotion and other app subnets) and some VLANs specific to each site. Therefore, the VLAN list trunked on each site for workload NICs is slightly different.
To assist with vMotion (and following the traditional VSS technique), I had intended two vDSs - but even two separate vDSs can't seem to have the same named Distributed Virtual Port Group. (see attachment).
Is my solution to have one dVS across the two sites, with two separate uplink groups, both with vlan tag restrictions? (in screenshot 2). Would this work, or is this setting for policing rather than working out if a path is local/remote? If I have a VLAN in common between the two sites, would this still function?
Lastly (just to understand the architecture) what would happen to traffic put in a port group for whose vlan-uplink was not on that VMs' host?
