Yeah, I'm having a hard time coming up with an easy enough
the user. I agree with Dan though, the bus renumbering risk would be
fairly low in the custom hardware seeing the switches are likely going
to be directly soldered to the same board with the CPU.
I am afraid that soldered down assumption may not be valid. More and more PCIe cards with
PCIe switches on them are becoming available and people are using these to connect servers
to arrays of NVMe SSDs which may make the topology more dynamic.
