Microsoft Windows Server 2019 is now available, so it's a good time to have a closer look at the Windows Server licensing.
As of September 2016, Microsoft introduced Windows Server 2016, including a new licensing model:
- Every physical server must be licensed for every physical core in the server.
- Every physical processor must be licensed for at least 8 physical cores.
- Every physical server must be licensed for at least two processors, thus at least 16 physical cores per physical server.
- Client Access License (CAL) required, which is calculated per device and / or per user.
Until September 30th 2016 it was possible to purchase the Windows Server license per processor + Server Client access license (CAL) model.
Microsoft end users with Windows Server Processor licenses including active Software Assurance (SA) have the option to upgrade to Windows Server 2016 at no additional cost. If processor licenses are still being used in an ongoing agreement with Software Assurance, then there is the possibility of using these processor licenses and the option to re-order until the end of the agreement. At the end of the Software Assurance period, "per processor" licenses will be exchanged into "core licenses" and the Software Assurance can be extended.
Every Windows Server processor license is converted by Microsoft into 4 core licenses. Each license covers 2 cores. (4x2 = 8 cores).
If you have servers with more than 8 cores per processor, it is possible to request additional core licenses when renewing the Microsoft contract. Microsoft does ask for this number of cores to be captured and to save the evidence as proof.
For our FNMS users, it is important that the Windows Server license in the FNMS system is converted to the Server Core model instead of the server Processor model. This also applies to the System Center licenses which, in the same way as described above, make a transition from Processor to Core Licensing model.
