How the heck does the OS see it as a single system, is there some pcie or rdma black magic that allows the kernel to just address memory in a different chassis? Maybe CXL?
Sounds like a HPE Compute Scale-up Server 3200, but again keep in mind that's something where there's probably a fabric between nodes one way or another.
It's bit cheating because it's cluster based system: https://www.hpe.com/psnow/doc/a50004268enw
So 4 sockets per chassis, up to 8 chassis in a complete system. Afaik OS sees it as single huge system, that is kinda their special sauce here.
