There are a couple of pieces to the Fail Over Group. The first is load balancing, and the second is fail over.
In your case the basic process is.... DTU comes on-line gets DHCP from DHCP Server looks up sunray-config-servers tftp's a .parms file from sunray-config-servers reads .parms file for server conencts to server server starts CAM session. what you will want to do to make this process use both servers in the failover group for as many steps as possible is: make sunray-config-servers a round-robin DNS between the IP's of the FOG servers create/modify the .parms files on both FOG servers to have a servers= line that contains BOTH Sun Ray Servers Add a select=random line to the .parms files This will load balance both the TFTP step and the initial display connection step. The built-in SRSS load balancing will take care of spreading out the sessions across the members of the fog. These steps also facilitate failover if one of the members of the FOG is down. Note that fail over does not mean that your Sun Ray session is copied to the other FOG member. The resumption of your work is maintained at the Terminal Server Level, so it's important that you do not enable the destruction of disconnected RDP sessions.
