Microsoft Windows Server 2019 Standard License

Microsoft Windows Server 2019 Standard - License - 2 Core Volume - Microsoft Open License - Single Language - PC
Mfr #: 9EM-00653

Microsoft Windows Server 2019 Standard - License - 16 Core Volume - Microsoft Open License - Single Language - PC
Mfr #: 9EM-00652

Please my friend uses only the 2 Core Volume license on his server and it works fine. But the licensing datasheet shows that you need a 16 Core license for such a physical server with a single processor of 4cores.

Please can anyone explain how this manages to work for him. because he doesn't know either.

Hi,

The licensing datasheet is for VMs, for example if you need your host to run three VMs instead of two. You need to meet the minimum.
So if you have 16 or more cores, then you must license all of those cores again in order to get permission to spin up two more VMs.

If you have no need for VMs, then they are working fine.

Hope above information can help you.

Thanks, @JennyFeng-MSFT for your response.

That means I can use the 2core volume license for my server as long as I am not using VMs.

Please kindly confirm this.....

I think he is asking if he can use a single 2 core pack to license the server

He actually needs 8 x 2 core packs for the server to be fully licensed as that adds up to the minimum 16 for a single physical machine.

Hello,

Please clarify once more:

A server with 1 physical processor with 4 cores can be licensed for Windows Server 2019 Standard using a 2 core license (9EM-00653) if there is no need for VMs on the server?

Thank you

Please could you clarify the following:

A server with 1 physical CPU that has 4 cores can be licensed for Windows Server 2019 Standard with a 2 core license (9EM-00653) if there is no need to run VMs on the server?

Thank you

That seems to be breaking the 16 core minimum required
One server would need 8 x 2 Core license packs to be licensed properly.

That would allow it to run windows and have up to 2 windows Virtual Machines on it.
If he runs more than 2 windows VM then he needs an additional 16 Cores per 2 above the first two.

Indeed, Microsoft licensing is so complicated even their own employees can't get it right
