No , I have not tried Unraid, just ESXi because I have been using ESXi for over 12 years. I was able to get it working on 6.7U1. I have not tried any other versions yet. I will try 7.0U1 in the future. I wanted to let anyone know that this will work in ESXi though (at least 6.7U1) if anyone is searching and stumbled across this thread like I have.
Cheers!
