With the System Centre Configuration Manager licensing model now changed into the Core Licensing model there has been various sources which give an explanation and breakdown of how the licensing works, but not necessarily enough that provides a real breakdown and examples of how to work it out.
So i have developed a licensing tool which is a spreadsheet which contains formulas that works out the licensing which is required for each server that has an SCCM role or a hyper visor which hosts VMs which use SCCM server roles.
Below is more information on the tool and a small breakdown of how the licensing model works.
This spreadsheet has formulas added to specific columns so that it can work out the following information;
Example 1 – Non Host
If there is a server that has 2 processors at 12 cores each which is 24 cores.
Each server requires a 16 core license at a minimum, so then you need to make up the rest of the cores by getting them by the 2 core licenses.
As 16 cores are covered you need 8 more to make 24 cores, so its 4x2 core licenses.
Example 2 – Non Host
If you have a server with 4 processors and 10 cores each which is 40 cores.
As every default requirement is to have a 16 core standard license per server, you would purchase a 16 core license. But as you have the option to buy additional 16 core licenses you would buy 2 which makes it 32 core licenses.
Then you only have 8 left to make up the rest, so you would then purchase 4x2 core licenses to make it a total of 40 cores.
Example 3 – Hyper visor Host
If you have a server which has 2 processors at 12 cores each making it 24 cores, but you also have 3 VMs running.
You would purchase the minimum requirement of a 16 core standard license. But as the caveat is that the license only permits you to run 2 VMs maximum, you would require another 16 core license.
Though this would make 32 cores, because the 16 core standard license is applicable to 2 VMs running, you still have 8 cores to make up on each so you will need 8x2 core licenses to make it 24 cores for each.
Example 4 –Hyper visorHost
If you have a server which has 2 processors at 6 cores each, making it 12 cores but you are running 6 VMs.
You would need to purchase a 16 core datacentre license, which will permit you to run an unlimited amount of VMs on your host.
