I am at a loss and could really use some help. I have an Unraid server that I use for Plex. I want to add an Nvidia Quadro P2200 for hardware transcoding and I am having no luck. When I add the P2200, Unraid boots and sees the P2200, but no longer sees my SAS controller or any drives. If I remove the P2200, Unraid will then see the SAS controller and boot fine. I did some research and I think that the issue might be that my SAS controller is PCIe 2.0. So, I purchased a new SAS controller that is a PCIe 3.0, but this one doesn't work at all. Unraid boots with this controller installed (P2200 is not installed) but it will not see any drives. So now I'm back with my original SAS controller installed and Unraid is working with all my drives showing, but I'm sitting here with a $500 video card and a $200 SAS controller on my desk that don't make very good paper-weights. Any help or direction would be greatly appreciated!
