I can't recall exactly, but I thought there was some guidance a few years back, to avoid 4-way and only go 2-way? I know there's the obvious:
• Price of Quad Socket Servers
• Slower clock speed
• Balancing PCIe devices across 4 procs, instead of 2 (GPU's being the big one you'd want balanced)
Thought I'd start a conversation and see where it goes...

10/17/2024, 1:25 PMIn my mind, benefits of doing dual-proc, would be:
1. Balancing PCI-e Devices, such as NICs and GPUs across the CPUs would be easier.
2. Higher clock speeds
3. More hosts in Dual-Proc configs, losing a host is less detrimental.
4. Less users on a host, failure of a host isn't as painful
5. Easier to evacuate a host
6. Less opportunity for cross-NUMA data and communication

Additionally, what Sprint found was the loss of a quad socket host caused a much larger amount of users to re-login on the remaining hosts. The worst thing you can do to a host is login. So, they actually had an incident where one host failed. Everyone logged in again. This caused a short period of slowness, which caused other users to logout and back in again, prompting more slowness, and eventually bringing down their environment.
