Deployment Advantages of Two- and Four-Socket Server Platforms

Intel IT and Intel’s Data Center Group conducted proof of concept (PoC) testing and total cost of ownership (TCO) analysis to compare two- and four-socket servers based on Intel® Xeon® processors for a variety of virtualization scenarios.

To conduct the PoC, we tested four different servers using the VMware VMmark 1.1.1* virtualization benchmark suite. A four-socket server based on Intel® Xeon® processor 7560 delivered 2.15 the aggregate performance of a two-socket server based on Intel® Xeon® processor 5670. Based on our test results, we then compared TCO and other advantages of each server in different scenarios.

Our analysis indicates that four-socket servers based on Intel® Xeon® processor 7500 series offer advantages in a number of scenarios, due to their higher performance, much greater memory capacity, and additional reliability, availability, and serviceability (RAS) features. These scenarios include:
• Hosting a large number of virtual machines (VMs), with a very large aggregate memory requirement, as cost-effectively as possible.
• When hosting requirements include very large VMs, requiring four to eight virtual CPUs and memory-intensive VMs requiring memory of 32 to 64 GB or more.
• When running a mix of memory-intensive and compute-intensive workloads, or when the workload mi is not known in advance.
• Data centers constrained by SAN or LAN connectivity or rack space limitations.
• When seeking to maximize virtualization cluster capacity for efficiency and ease of management.
• When maximizing RAS is a key design goal, such as when running mission-critical applications.
Two-socket servers based on Intel® Xeon® processor 5600 series offer advantages in maximizing performance per unit cost or performance per watt in deployments of small to medium-sized VMs.
