Windows Server VM License based on VMWare ESXi 5.5

[bylmy]

We have plan to purchase Windows Server 2012R2 Standard Version to build up our new system. In our blue print there are two physical DELL servers with VMware ESXi 5.5 installed, then 3 windows server 2012R2 virtual machines will be deployed on each physical server, that means total 6 windows server 2012 R2 for two physical servers. So in this case we would like to know is that OEM Windows Server 2012 R2 Standard 64-bit fit our request and how many sets can be covered all of 6 VMs, or I have to select retail version? Any help would be appreciate.

Welcome to the Community - I believe Standard only allows for 2 virtual instances so to support 6 windows VMs you will need 3 licenses - also pay attention Windows licensing is no per processor.

But you realy should confirm with Microsoft dor the official license information -
