@scottalanmiller Standard - per core pricing for 8 cores would be 4 x 2 core packs that cost $3,717 each.

For a total MSRP of $14,868.

That is if SQL Server requires you to license all physical cores or not. I never looked. I assume it does, but I cannot say it does.

Well I'll be fucked. You can license per virtual core.

Minimum is 4 cores (physical or virtual).
Physical, you license all cores.
Virtual, you license per vCore assigned to the VM.

When did THIS change?? WTF

[scottalanmiller]

@jaredbusch one of the complications is that there IS no virtual core. vCPU is NOT core.

Don't get bogged down in the semantics, you license each vCPU in the guest.

But traditionally, it WAS that semantics that determined the licensing.

a vCPU has vCores. Always. It might just be one. That is how it works.

[Obsolesce]

It was like 2 years ago, and it was MS SQL 2014, we licensed a VM (4 vCPU) and it was not anywhere near $30k. If I remember correctly, it was only a few thousand dollars, unlimited users, 4 vCPU.

Not in any system I've seen. What people call vCores are actually vCPUs. The vCPU might tell the OS it has multiple cores, but the idea of a vCore has never existed, only vCPUs. Vmware, KVM, etc. all the same. Core means physical, it's like having a physical virtual, it cancels itself out.

For MS SQL Server 2014, but may still apply:

For MS SQL Server 2014, but may still apply:

So at some point, MS made a new, industry conflicting term. vCPU has been standard and means something at the hypervisor level. The MS term is an MS only term.

I also see this:

So if you have hyper-threading enabled on your Hyper-V host, and you give the VM 2 vCPUs, you need to license for 4 cores.

Edit: This is also for SQL 2014, not sure about 2017.

That's tough as most deployments, people don't know what is supporting the vCPU. It's also confusing that this seems to ONLY apply with Hyperthreading in one case, but multiple cores in the second. Why does the HT get mentioned, given the second statement?

Who knows.

But here you go, just found this for 2017, which also confirms the above:

I am almost certain that VMWare lets you make a 1 CPU VM with 2 cores.

Hyper-V just says virtual processors.

KVM says CPUs.

But I very clearly remember some hypervisor letting me specify a vCPU and vCores.

VMware lets you specify how many CPUs, and Cores to "pretend" to have, but each is just a representation of the vCPUs. The vCPU unit is calculated from "presented CPUs * presented cores". But each core or CPU you present, is a vCPU.

KVM does let you:

Right, it's a presented topology. How you want the vCPUs to "look".

The wording on XenServer is more clear. The vCPUs are the things you have, the topology is how they look. It's less confusing in how they show it.

[Obsolesce]

Right, so what's the issue?
