Hyper-V: Vm replica and Microsoft Licenses

[Dotmax]

Hi to all, not sure is the right place to aks this, but i need an information.

I have 2 Hyper-V Hosts (nothing shared, 2 single workgroup hosts with local storage).

The first is the main server (with 1 VM running our application, and 1 VM running "MSSQL server Standard server licence", as the db backend for our application)
The second is a backup/DR server (with 2 vm replicas, powerded off, made by B&R).

My question is: do i have to buy 2 windows server licenses? one for the master and one for the replica? or (given that the powered on vm will be always only one) is ok if i buy only one license?
Same question for the MSsql server license, the running instance of sql server will be only one, is one license enough?

Thank you
Max

Hi Dotmax,

It would be best for you to discuss this with your license supplier/Microsoft, as only they can give an authoritative answer on license requirements when replication is involved.

I understand you're hoping for some guidance and maybe others can share what they were told, but for a reliable answer for your licensing requirements, you should ask the license vendor to avoid potential misunderstandings and license violations.
