This question came up last week asking for a programmatic method to identify whether NSX-V or NSX-T is deployed in your environment. With NSX-V, vCenter Server is a requirement but for NSX-T, vCenter Server is not a requirement, especially for multi-hypervisor support. In this post, I will assume for NSX-T deployments, you have configured a vCenter Compute Manager.

Both NSX-V and NSX-T uses the ExtensionManager API to register themselves with vCenter Server and we can leverage this interface to easily tell if either solutions are installed. NSX-V uses the com.vmware.vShieldManager string to identify itself and NSX-T uses the com.vmware.nsx.management.nsxt string to identify itself.

Here is a quick PowerCLI snippet that demonstrates the use of the vSphere API to check whether NSX-V or NSX-T is installed and provides the version shown in the registration:

Here is a screenshot from my environment which has both NSX-V (6.4) and NSX-T (2.1) installed:


Note: Due to some current testing, I have not upgraded my NSX-T deployment to the latest 2.2 release, so I do not know if the version gets bumped to match the actual released version
