joe.sDell response to a request for getting a set up as I initially described was
"it is unlikely that we will get a resolution to this issue with the current setup (even with the latest firmware in place).
Ultimately what you are trying to achieve is outside of the ‘supported operations’ for the T620 Server, based on its Server ‘architecture’.
The display options and Graphics setup for these particular Servers are only supported in a specific configuration and unfortunately it would appear that your preferred configuration will not function."
But you understand why that is the answer they give ... it is the only answer they CAN give. They do not have ANY documentation from the people who designed and worked with these machines as to what will and won't work and how - and no doubt the engineering teams did NOT test anything that was not a designed feature or function of the server. The support agents also do not have access to machines to try anything on their end (although frontline agents can escalate troubleshooting of SUPPORTED features/functions to an analyst(s) to be attempted on a real/live/test machine). Dell's only response can be "it is not supported", so it is up to users to try it and to troubleshoot any situation outside of Dell's design parameters, which are sufficient for more than 99% of users/uses. Same thing with installing, say, Windows 7, on it ... it is not supported, but that doesn't mean it won't work, just that Dell will not assist you in attempting it, because they can give you no guarantee that it will work, not being purposefully designed to run it. If you were opening a case with a Dell engineer (which isn't possible), they might be able to give you better insight into what will and won't work and why, but the frontline agents are given only the information on the system they need to assist customers with system hardware and other supported scenarios.
