Hi,
One suggestion for future performance tests under the category Virtualizing Business Critical Enterprise Applications - Microsoft Dynamics AX 2012 (R2) running SQL Server 2012 SP1 with Analysis Services, Reporting Services and SharePoint Foundation 2010 with special focus on AOS (application server) and SQL Server performance characteristics.
Why? Since Microsoft has it's own hypervisor in Hyper-V, they will never invest in such performance tests (I bet), but a lot of customers are in fact running AX on vmWare. And AX is a mission critical application since it's an Enterprise Resource Planning application with a typical OLTP load (also some OLAP load).
I think a lot of people would appreciate such an initiative to get some facts on the table.
Microsoft has done a benchmark comparing the performance on the same hardware for 3 implementation scenarios: physical, virtual and mixed. The test showed a two digits (percentage) performance loss when running all servers as virtual and a little less when the SQL Server was running physical and all others virtual. The SharePoint server (AX Web application called Enterprise Portal) was not supprisingly the best candidate to virtualize in this benchmark. Since the document is partner restriced (Partner Confidensial), I can't publish the report here or give the real numbers. I can ask for permission to share it if this is of interest.
I don't know how to vote for applications to test, but it's worth a shot. AND I'm aware of the benchmarks for SQL Server and SharePoint, but it's still the application that makes the difference with it's unique characteristics.
