Licencing Server 2019 DataCenter - HyperV

Colin A 1 Reputation point

One of our customers has 2 copies of MS SERVER 2019 DataCenter, as we have a PRIMARY Hypervisor with 2 CPU's.. This is running their "LIVE" VM's

Next to this server in the rack, they have another "old" server, and we want to use this as the REPLICA server.., so nothing running on it, just sitting there in the event of a DR... Hyperv will replicate the VM's over to it, but they will not be live..

Do we need to buy more SERVER 2019 DataCenter licences..?, I can't see we would as this is not live and no VM's are spun up on it...

I would be grateful for anyone's advice..?

    Sounds like you may be Ok with two licenses. Each host needs to be licensed for all cores.

    So, the PRIMARY HV has 2 CPU, and we therefore have 2 copies of SERVER 2019 DataCenter to cover each CPU.., so the PRIMARY is legal.

    It was really if we need to buy further licences for the secondary machine which is just running as a REPLICA will all the VM's off..?
