Is anyone aware of a method whereby I could force a particular DTU to authenticate to a particular server all the time. In my setup, I have two Sun Ray Servers and 24 clients, I want to split the clients up evenly between the two servers and force 12 to always authenticate with one server and the other twelve to authenticate with the other server. Using the Sun Ray load balancing is not an option since I have 4
Do you mean the SunRay FOG (Fail-Over Group) as load balancing? If not, explore the FOG option first, it might be better ;)
critical workstations (DTUs) that can’t all be down at the same time, which is a possibility when using SRSS load balancing.
Well, in layman's terms, the DTUs can't be "down" - they don't do anything by themselves anyway, they only paint the server's X session. So by having some DTUs connect to just one server only, you would only add a SPOF, I think - they would not fail over to a working server if "theirs" one fails. Still, there is a number of solutions. Off the top of my head: 1) DHCP: you can try to have the different DTUs receive different options from your DHCP server (AuthSrvr and AltAuth macros; perhaps listing same servers in varying order). 2) DNS: If you use DNS to find names "sunray-servers" and/or "sunray-config-servers", you can use different ISC BIND "DNS Views" to return different information to clients (DTUs) based on their IP addresses. 3) VLANs/dedicated network segments: You might want to set up different VLANs providing one sunray server each, and assign the DTUs to access a certain VLAN. For quicker tests you can just use the GUI firmware and type in the different settings for the particular DTUs, to see if such segregated solution actually suits you at all.
