VMware, introducing new license model made a big confusion among users, admins and customers especially with free version of vSphere 5 ESXi hypervisior. A lot of people wrongly interpret or have a problems with correct interpretation. In this post I will try to explain ESXi free license in” human readable” format
Let see what VMware documentation states:
VMware vSphere Hypervisor
VMware vSphere Hypervisor is a free product that provides a simple
and easy way to get started with virtualization at no cost. vSphere
Hypervisor provides only basic virtualization capabilities allowing
to virtualize servers and run applications in virtual machines in a
matter of minutes. vSphere Hypervisor cannot connect to VMware
vCenter Server and therefore cannot be centrally managed. Users
can remotely manage individual vSphere Hypervisor hosts using
the vSphere Client. vSphere Hypervisor is entitled to 32GB of vRAM
per server (regardless of the number of processors) and can be
utilized on servers with up to 32GB of physical RAM.

What does it mean ? Basically means that you can run ESXi 5 free version on a physical hosts which has max 32GB RAM and as many CPUs as physical host can support (number of CPU sockets are not limited in ESXi 5 free version only RAM is limited). I hope it’s clear now but what about VM’s configuration ? Well, max RAM size for VM is 32GB of RAM and 8 vCPU.
