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.
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?
