Good morning.
Is it possible to just license the 3rd host with a View license and set up DRS rules so that servers stay on the first 2 hosts but VDI can use all 3?
Possible, yes. Recommended, no. Possible license violation, yes.
Will having the servers on the SAN and VDI clients on VSAN cause any issues?
No.
For my cluster network, can I have dual port 10GB cards in the hosts, connect one port to each host and use routing to route the cluster traffic over the correct NIC to the host?
Possible, yes. Recommended, no. It has been discussed in the forums before. Physical interface bridging possible in ESXi ???
From my personal experience and involvement in the forum, this type of setup when used in production leads to problems. I would not do it. Thank you, Zach.
