2 socket servers are actually the norm and dominate datacenters. 4 is still common but usually only done for the ability to address a large amount of RAM in a single machine or niche commercial workloads. 8 socket x86 servers are very unusual.
- shaklee3 7y agoTo add context, this is mostly because the numa properties get weird. With 2 sockets all of the inter-socket links can go directly to the other processor, and xeons have 2-3 of those currently. With 4 and 8 you end up having strange memory topologies that has hops that are less predictable unless you know your application was written for it.
