# of Windows Server Licenses needed for my server

Hi,

 I have a new server with two INTEL XEON SILVER 4110 @2.1GHZ 8 Core CPUs on MB and like to know how many Windows Server 2019 standard license that I need to purchase.
 I am going to create three virtual machines in Hyper-V server.
 As I understand it, each server license covers two VMs, so I need total two server licenses and end user CALs?

Thanks.

Standard wisdom on EE is that licensing questions should be asked of the manufacturer.  "I read it on EE" will not be a good defense if you make an error!

You can discuss it with Microsoft or with your vendor.  

Last time I purchased server licenses, they were sold 2 cores at a time and you had to buy a minimum of 8.  The cost of 8 2-core licenses is about the same as the old-style single license.

From my understanding (with the warning that I have no authority on this), you'd need 16 2-core licenses (basically, two full server licenses).  That will allow you to install the host (that does nothing but host the VMs) and up to 4 VMs.

Microsoft has since "simplified" licensing by now having a base license SKU covering the first 16 cores, and then the 2 core add on packs. I don't know if you need 1 base license and then 8 x core add on packs, or two base licenses. Ask your reseller. At any rate, you have the correct general understanding on how to license.

I will talk to Microsoft. Thanks you all.

That is correct.

One Server Standard license covers 2 guests. So, in this case 2 Server Standard licenses plus the applicable version CALs would be required.

Since a Server license covers 16-cores by default you're good to go on the core count side of things too.

As an aside, if one VM will be a DC and host file, print, and back end database utilities (Sage, Intuit) I suggest using that fourth VM to host the file, print, and Db back end components.
