RDS Farm across two subnets

Posted on 2014-12-01
Last Modified: 2014-12-16
To put it simply I am curious if there are limitations with having RD Session hosts in the same collection across two subnets. I have added one to an existing farm but it throws an error and no remote users get directed to it.

Here is what we have going on. We have two datacenters, our HQ which is VLAN 800 (10.200.x.x) and our remote failover site on VLAN 806 (10.206.x.x). We have an RDS Collection that our remote users connect to, there are two blades in HQ and we are planning for two blades at the remote site for failover/load balancing. The problem is that when I add the RDS host server from the remote site to our RDS Collection in HQ I get an error (which I can ignore and it get added to the collection anyway) and no users are routed to that host.

What you need to do is set up a proper fail over and be able to test it This entails having 2 of everything that is essential. With RDS cal's this will double your cost. As you will need 2 license servers and 2 rd-hosts.

That's kind of what I figured. So having a live environment across two subnets isnt going to be possible then?

Then it is not a fail-over but a high availability scenario,.. It is doable but as I stated it has higher costs. Making it transparent to the user is the hard part, but you'd have to have part of your DNS located outside of the current 2 physical areas.

I see, so if I was going to setup HA over two subnets across a WAN link I will need to use two brokers, license servers etc? There doesn't seem to be alot of documentation on this particular setup for Server 2012 RDS

the pricey point is the item that detects if the local network is down and routes it to the offsite network.. or simply use your domain settings from the domain registrar to point to your network and then all you have to do is change the A record to point to the offsite network. (keep your ttl small like 1 hour)  Personally I use cloudflare since domain registrars are usually terrible when it comes to domain management.
