Both peak and average CPU utilization data showed a consistent increase as the load increased from 1 to 8 virtualized databases, as shown in the following figure. The net CPU utilization in the S2D cluster was 604 GHz, which shows that the eight virtualized databases with a peak CPU utilization of 245 GHz did not come close to using all the processing resources of the cluster. Thus, importantly, the SQL Server database on the hyper-converged solution had plenty of unused CPU to support additional databases.
