Dual socket servers – servers that ship with two “sockets” to support two centralprocessing units (CPUs) − are the mainstay of nearly every datacenter and server room. But walk through any server room or datacenter and slide three servers on their rails, pull off the cover and you will probably find at least one of those servers will be populated with only one CPU. And if you go to a console and run the performance monitor (PerfMon) utility against any server, you’ll more than likely see CPU utilization inthe 25% - 35% range.
Advances in CPU microarchitectures and design have led to server platforms that can reach incredible performance levels. In many cases, compute power and resources are overmatched for the workloads supported. Even in large enterprise IT organizations, CPUs sit highly underutilized. This begs the question – why continue to deploy two socket servers if they are underutilized in your server room?
