Windows Server 2016 Licences for cluster
-
@Dashrender said in Windows Server 2016 Licences for cluster:
Here's an easier situation.
You have two servers in a failover cluster, you purchase one DC license. You run 100% of your VMs from just one of the two nodes in your cluster. You can move all those VMs to the other host as often as you like under this SA mobility allowance.
So, it's patch Tuesday, you patch the unused server, reboot it, done
You then migrate all VMs to the patched server, transfering the license to that one server
now you patch the unused server, reboot it, done
Now you can move all the VMs backIf you didn't have SA, you could not legally do the above process (specifically that last step) unless you license both servers for enough Windows licenses to cover your needs.
To clarify for the eventual stupid that will come up.
The above works when Hyper-V Server or XS or KVM or VMWare is the base Hypervisor.
You cannot do that if you try to install Server 2016 Datacenter on the hardware. In that case, you need both licensed.

Yeah - JB had a phone call with MS or their agent and basically shut them down because they were telling him that he needed to license the passive failover server for the number of licenses that could be running there. Your post says differently

But what I'm thinking, is that because of this:
...you could just move the OSE DC license (along with all 50 VMs) to the other Node in the cluster. That way the passive failover server would be properly licensed.

Yes. As long as everything goes with it, you can do that. Once ever 90 days without SA, or whenever you want with SA.

This turned into an awesome discussion. I need to bookmark this one, some dynamite licensing info here.

Guys you are wrong in your interpretation. The Server pool rights you are referring to are a general guideline, each Server Application is different. To understand the rights you have with a specific application, in this case Windows Server, you need to look at the Product Terms specific to Windows Server starting on page 45.
No license mobility!
Therefore you cannot move vm's more than once per 90 days just by having SA, you need to be properly licensed meaning you have a Windows datacenter license on each host, or sufficient standard licenses to cover the maximum number of vms on EVERY host in the cluster at once.
In this example, you need either 2 datacenter licenses (which would be overkill for such a small number of vms) or 2 standard licenses on EACH host. (4 licenses total or the equivalent in core licenses)Look at the licensing for SQL Server, its different, it clearly spells out that SQL with Software insurance includes License Mobility. Windows Server does not.

@Scott_AssetLabs well that's crap
But makes more sense.

That was basically where I was 2 years ago - but clearly I didn't find the correct docs for my original thinking.
