search for "nvidia vm passthrough" until you come across instructions on modifying the nvidia VBios for your card. There is a header which must be removed from the vbios file(using a hex editor) I do believe SpaceInvader has more than one video on YouTube demonstrating the procedure. I have the same gpu and this step was necessary

used these to make my custom banner

a little KDE Neon love

I am on the board of directors for Bliss OS which is an Android based operating system developed for x86 hardware. Cheap plug here :-) but this is the icon i use for my test VM

From what I can tell(from reading a lot!) is that when the h310 is flashed to IT mode, it does support TRIMM commands for enterprise level SSD's. My SSD(I own 2 nearly brand new): Intel DC S3510 Series 1.2TB

I did try this: label unRAID OS menu default kernel /bzimage append iommu=pt initrd=/bzroot I added "iommu=pt" to each of the boot options in the syslinux.cfg as you suggested and as I've seen mentioned in other threads here on the forum. It did not affect anything. Still get errors during boot and ssd/sata3 control card undetected by the OS. The performance gain from using the Dell PERC H310 should pay for itself in the long run versus this StarTech brand card. I didn't have time or patience to fiddle with option roms/firmware/bios flashes for this StarTech card. I also paid a little extra for the H310 I found which is said to have been pre-flashed to optimal firmware/bios/option rom and tested in use with the UnRaid OS. Should have the part and cables by Friday and ready to move forward with everything else :-) I very much appreciate your responses and trying to assist me. In the end, I chose to replace the part in question with a better & hopefully fully compatible one. We can call this subject matter resolved, and thread can be archived. Thanks again @saarg

I require the capability to passthrough hardware to my VM's.... including my MSI GTX 1050Ti 4gb OC GPU. So in the long run , disabling VT-D will not be an option for me. I've read some discussions of flashing a more recent firmware to the controller may work, but there is a lot of inconsistency in people finding success with this. I've located a recent firmware file, but i'm not really comfortable with flashing different firmware/bios files to an item i may end up returning.therefore this PCIe card may need to be replaced. :-( instead.... I believe i am going to get this card: Dell H310: https://www.ebay.com/itm/162834659601 Already having an older device, i'd rather limit compatibility issues between hardware and UnRaid.... as I imagine I have a big learning curve moving forward when trying to make the hardware play nice within my VM's. I'd rather go with a slightly more expensive PCIe card and limit the hastles of getting this StarTech(or other buggy Marvel chipsets) to work properly. From what i've gathered here on the forums, this H310 SAS/SATA controller is listed as compatible with UnRaid OS. It is also mentioned as being a top performer(read/write speeds) in Z800 forums. It is described as giving the Zx00 series the same SATA3 performance as the Zx20 series machines(they use the same LSI controller) There is also RedHat driver support for a long time for the H310, so my Arch based Linux distro(Android build enviroment) SHOULD play nicely with the hardware....... we shall see. Am going to pull the trigger and order the H310 right now. Will take 5 days to be delivered, in the meantime I can focus on getting my VM's installed and configured as i'd like, and then swap out cards later and enable the harware passthroughs at that time. Baby steps to getting my machine fully operational and modernized/upgraded :-)
