Passthrough SATA Controller

[shuhdonk]

I have a Supermicro H12SSL-NT motherboard that has 2 slimsas ports on it, you plug a cable in and each cable has 8 sata connections for hard drives. I am curious if you can pass through one of those ports to a VM? I am new to Proxmox and linux and not sure exactly how this works. If I go to a current VM and I go to add hardware it lists 4 of these in the list (photo attached). I am not sure if those are those slimsas ports or not though, the FCH SATA Controller's listed.

Also, how can I tell which controller or port my hard drives are plugged into, is there a way to list where/what the drives are connected to? I have 2 ssd's connected to one of slimsas ports (proxmox is installed to them, they are mirrored).

Thanks for any help.

You might be able to get that info from ls -l /dev/disk/by-path.

It seems you have 4 SATA Controller entries, all in different IOMMU groups. Perhaps it will be possible to pass through one or more of those.
