What is a Standard core add-on?

It adds additional licensed cores to a Standard host.
Used when your server has more physical cores.
Sold in small packs for accurate core matching.
Helps keep licensing aligned with installed hardware.

How many core licenses do I need per server?

You must license all physical cores on the server.
Each CPU must meet the required core minimums.
Each server must meet the required core minimums.
Add core packs until all installed cores are covered.

What is the difference between Standard and Datacenter core add-ons?

Both cover physical cores, but virtualization rights differ by edition.
Standard includes limited Windows VM rights per licensed set.
Datacenter includes unlimited Windows VM rights per host.
Choose based on how many Windows VMs you run.

How does licensing work for more than two Windows VMs?

You stack additional core coverage to gain more VM rights.
One fully licensed core set typically covers two Windows VMs.
Add another full core set to cover two more Windows VMs.
Plan by counting Windows VMs and host core totals.

Can I use Standard core add-ons in a virtualization cluster?

Yes, but every host that can run the VMs must be licensed.
License each possible destination host for mobility scenarios.
Keep core totals and VM rights consistent per host.
Document host coverage to stay audit ready.

Do I need Windows Server CALs too?

Yes, server access rights are typically handled separately from core coverage.
CALs are commonly required for users or devices accessing services.
Core licensing covers server capacity and virtualization rights.
Plan both sides to avoid compliance gaps.
