The relative positioning of 2 and 4-socket servers for server virtualization has been an open question for a long time - a question that has stumped the most astute of IT professionals time and again. In fact it might not be an exaggeration to say that this open question is almost in the same class as the famous Riemann's hypothesis that has remained unsolved for over a century! (If you accept that premise, then there's some real estate on the moon that I'd like to bring to your attention as well). Although advocates for either class of servers have been emphatic in their respective positions, compelling data-points supporting their positions have been few and far between.
To remedy this sorry state of affairs, an Intel IT team conducted in-depth tests and analysis using current quad-core processor based 2 and 4-socket servers in a virtualized environment. This effort culminated in a comprehensive framework for comparing server platforms for virtualization. This comparative framework encompasses the majority of common deployment scenarios and usage models and answers - once and for all - the long unanswered question "which server is more appropriate for my virtualization project?"
