Best practice with UAG HA for internal VDI access

Hello:

I am working on a project where we are implementing a new Horizon environment.  Right now I'm focusing on the internal connection servers and if they can be highly available with just UAG appliances in front of them, without a 3rd party load balancer involved.  It appears that the answer to this is no, as the UAG documentation I've been looking at says to put a 3rd party load balancer between the UAGs and in front of the connection servers.  Plus, in the Horizon configuration of the UAGs, it only has one entry for the connection server (or one VIP for the 3rd party load balancer).

My main question is, if we did try to use the HA feature of the UAGs, and each UAG is pointed at its own connection server so that there's no 3rd party load balancer involved, if a connection server goes down what will happen?  Is the UAG smart enough to fail over to the UAG that still pointed at a working connection server?    I'm guessing the answer to this is also no, but I would like to confirm, if anybody knows.

Thanks in advance!

Chris
