It also simplifies the administration because you do not to have to configure and patch another operating system. Unfortunately the vCSA is really rare in a production environment. In my opinion this is caused by the fact that the vCenter Server Appliance always has some limitations, which are often not completely understood.
Here are the limitations from the current version of VMware vCenter Server Appliance 5.1:Read More »VMware vCenter Server Appliance 5.1 (vCSA) Limitations
Are you looking for a free alternative for a Windows based Active Directory controller?

While doing some patchmanagement I faced an issue with the current Windows Management Framework 3.0 (WMF) and the VMware vSphere Update Manager PowerCLI 5.1. Everytime when i invoked one of the VMware.VumAutomation cmdlets the PowerShell crashed with an StackOverflowException:
