Thanks, for responding, Andre.

First off, let me say that I'm relatively new to the VMWare world, though I've used Virtual Box on a couple of systems.

We are in the process of installing 5 physical servers (Dell R740/R440 mix) in our lab, each will have ESXi 6.7 installed.  With this we are getting

"vCenter Server" Standard licenses and the vendor's team will install vCenter on a VM.

When I searched the VMware site, I read that vCenter should be installed on a Windows system (I'm not sure what version of vCenter

we're getting; I suspect it's 6.7) and it can't be installed directly under ESXi , which I sort of understand.

So, to that end, we are also installing another real system with Windows 2016 Server.

Kind regards,
