fileserver vm and direct access

Hello,

i'm thinking about setting up a new proxmox host based on a C2750. Unfortunately the chip doesn't support Vt-d. So pci pass-through isn't available.

The board has 6 SATA ports onboard. I would like to have a dedicated fileserver-VM with direct access to 4 disks.

I am not sure where but I think i read once that you don't need vt-d for sata pass through as it's not a pci extension. I think this sounds weird that's why i'm asking to verify.

Are there any possibilities to give direct access to some hard disks to the fileserver vm? I just don't want any vhds of 2TB or more...

Thanks very much
