VMware vCloud Air Database Performance Scalability with SQL Server

Previous posts have shown vSphere can easily handle running Microsoft SQL Server on four-socket servers with large numbers of cores—with vSphere 5.5 on Westmere-EX and more recently with vSphere 6 on Ivy Bridge-EX.  We recently ran similar tests on vCloud Air to measure how these enterprise databases with mission critical performance requirements perform in a cloud environment. The tests show that SQL Server databases scale very well on vCloud Air with a variety of virtual machine (VM) counts and virtual CPU (vCPU) sizes.

The benchmark tests were run with vCloud Air using their Virtual Private Cloud (VPC) subscription-based service.  This is a very compelling hybrid cloud service that allows for an on-premises vSphere infrastructure to be expanded into the public cloud in a secure and scalable way. The underlying host hardware consisted of two 8-core CPUs for a total of 16 physical cores, which meant that the maximum number of vCPUs was 16 (although additional processors were available via Hyper-Threading, they were not utilized).
