even if we choose the diagram, the x8 you mentioned remains the same problem: x16 on the GPU to the Z590 totaling 24, and from the Z590 4 to the NVMe SSD with the remaining 4 going to the network and IO—this is what I’m trying to figure out where my calculations might be off.
The DMI is an x8 interface. It will perform more than adequately. Given that the typical speed cap for data transfers here is 10gbe, it stays well within the DMI's capacity. You won’t be able to use the DMI for copying data across the network regardless of your storage setup. The processor supports 20 PCIe lanes—4 dedicated to the GPU and 16 to the NVMe storage. The CPU also includes a DMI connection on its chipset, providing an additional 24 PCIe lanes (varies by configuration), bringing the total to 44 lanes. This capacity comfortably accommodates all connected devices. There are more than enough I/O ports available. You’re asking why this setup is suitable for a NAS? I’d recommend something similar to the ASRock Rack Board with X570—offering excellent support and integration options. Also, the backup uses SSDs; HDDs only should be reserved for storage, as they won’t significantly impact performance.
The main idea is that a 4x PCIe device passing through the chipset isn't taking over 4x DMI lanes. The chipset combines DMI into PCIe, so it can distribute up to 24 PCIe lanes among connected devices. This setup lets the shared bandwidth be spread across all 24 lanes instead of being fully consumed by a single device even when unused.
it has four pcie lanes shared among 24, which means if you're running the computer this way it might slow things down! the 10gbe connection won't cause throttling, but what about the rest of the disks handling data? your goal is clear—when you back up to NAS, you'll free space on your local drive so you can reorganize files and make copying easier. this way, you won't have to wait for the network transfer to finish before moving files quickly between disks.
