# Answer Question

### SQL Per Core Licensing and Core Factors

This should be a fairly simple question but a colleague has debated on the interpretation of the wording in regards to SQL per core licensing so I'm looking for a bit of assistance to put this to bed.

Example

Server A

# of Processors = 2

# of Cores per = 8

So the question is, there are obviously 16 cores here. Considering we buy the licenses in packs of 2, this can be interpreted as requiring 8 such licenses (2 core licenses per pack x8 = 16 cores covered).

The debate came in when applying the core factor. Do we then need to apply the core factor (x2 for dual core) on top of that or is the point of the core factor just to arrive at the same point?

The way Microsoft words this suggests that you have to apply the core factor to the total number of physical cores. This would mean that we would have to apply the core factor of x2 to the 16 cores essentially doubling the amount of licenses that would be required.

I have been looking for an example of this but haven't been able to find a definitive one.

This all stems from the language Microsoft uses to describe this licensing model.

"P hysical Cores on a Server. You can license based on all of the physical cores on the server. If you choose this option, the number of licenses required equals the number of physical cores on the server multiplied by the applicable core factor located in the SQL Server Core Factor Table ."

Some assitance on this would be greatly appreciated!
