Hi all,

Have Physical Server with 2 Processors. Each processor has 8 cores. This means I have 16 cores in total (physical). However, there is feature on server to activate virtual cores, when doing this, I get 32 cores.
Physical Cores = 16
Physical + virtual Cores = 32

Now if we consider the Windows Server activation for Windows Server 2019 Datacenter, I have valid product key for the DC which I used to activate the server. Should I need to consider take other actions to activate Processor cores in addition to Operating System activation? If yes, please advise how?

    Hi,

    You don't need to activate processor cores, just use the product key to activate the server that you can have the operating system activated.

    Hope above information can help you.

    Only the physical cores should count. Some general info

    • Each host needs to be licensed.
    • A minimum of 8 core licenses is required for each physical processor and a minimum of 16 core licenses is required for each server.
    • Core licenses are sold in packs of two.
    • Standard Edition provides rights for up to 2 Operating System Environments or Windows Servers containers with Hyper-V isolation when all physical cores in the server are licensed. For each additional 1 or 2 VMs, all the physical cores in the server must be licensed again.
    • DataCenter Edition provides rights for unlimited Operating System Environments or Windows Servers containers with Hyper-V isolation when all physical cores in the server are licensed.
    • AVMA keys can be used only when the host is DataCenter edition

    Hi and thanks for reply.

    Could you please elaborate the "Core License"? is it different from the Server License?
    I have following options under keys:

    And following keys: I can't see something specific about the core license.

    No, the licensing is the same for core installation.

    Some confusion left anyhow.

    As per my screenshot, I have Windows Server 2019 Datacenter - Retail KEYs.

    I am using this to activate the Server, once server is activated, all done? If yes, then why to get linked with number of physical cores and core licenses?
