VMware ESXi and vCenter Server.
First step is to install ESXi on a physical server. Download the latest version from VMware website (latest version was: 6.7.0 u3): https://my.vmware.com/en/web/vmware/evalcenter?p=free-esxi6
After the installation is done, get the IP for that host and will be used to install vCenter Server Appliance.
Second step is to install vCenter Server Appliance. This step will run from Windows. Get the latest ISO from VMware website (latest version was: 6.7.0): https://my.vmware.com/group/vmware/details?downloadGroup=VC670&productId=742&download=true
For this step you’ll use the IP from ESXi to install it.
