We matched the configuration and size of the databases and the VMs for the tests of both systems. The test methodology for the legacy system is a two-step stress test in which the first step is running a single virtualized database and the second step is two virtualized databases running in parallel. The test findings provide a detailed performance comparison between the legacy SQL Server architecture and the Ready Solution, and insights into the advantages of the new hyper-converged infrastructure.
The following figure illustrates the test configuration for the legacy SQL Server architecture.
