These virtual machines can be Server R2 Standard or Essentials edition. Similarly, if you install a Windows Server R2 Datacenter editionthen you can install an unlimited number of virtual machines. Scenario 2 : Install Server Standard Edition on a physical server with 1 physical processor, running 8 instances of virtual machines. Sfandard total of 50 users will be accessing the server. Remember that a single Standard edition license covers up to two physical processors and up to two instances of virtual machines.
Since the requirement is to run 8 instances of virtual machines, we need больше информации Standard edition licenses. If we decided to use the Datacenter edition in this t2, a single license with hyoer-v CAL would be enough to cover our needs, because the Datacenter edition license supports an va number of virtual instances and up to two physical processors.
