That said, here's how it looks assuming you'll be using vCenter. Licensing always tends to be a needlessly complex matter hence why it's best to talk to a reseller.

This is a pre-installed server for windows but it can also be used on Linux with a simple step to change from windows to Linux which can be asked on our Discord. If a vCenter Server license expires, the managed hosts become disconnected from the vCenter Server inventory, and you cannot add hosts to the inventory. License Expiration Upon license expiration, the vCenter Server software and the ESX/ESXi software continue to run, but certain operations stop working.In the window that opens, select Assign a new license key to this host and then type the license key when prompted. On the right panel, click the Configuration tab. On the left panel, locate and select the VMware ESXi server IP address.On ESXi hosts which have a sub-domain name with large, shared cookies a web console session may fail to initialize. We are working on a solution to this issue. On ESXi hosts which are assigned a VMware vSphere Hypervisor license, all modification operations will fail silently.
