Currently we would be using ClearPass for just wireless. To our instituion wireless is still a "nice to have" not mission critical. If we went down for minutes/hours it would be an inconvience.
When we start using ClearPass as our NAC for wired and wireless we will be forced to run a second ClearPassVM as then it would be a necessity.
I guess my question is more along the lines of "Does clearpass require two instances to run or can it run as a single unit?"
and it appears the answer is yes, but it's not best practice.
