I'm attempting to define servers in different VLANs/subnets in the same server farm. I can't find documentaton on this. Can you help?
there is nothing special to do.
It does not mater for the loadbalancer if the servers are directly connected or not.
You just have to guarantee that they are reachable and that the return path from server to client goes through the loadbalancer. [ this is usually the most difficult part].
