- ↑ 1.0 1.1 1.2 Each license of Windows Server 2012 Standard or Datacenter allows up to two processor chips. Each license of Windows Server 2012 Standard allows up to two virtual instances of Windows Server 2012 Standard on that physical server. If more virtual instances of Windows Server 2012 Standard are needed, each additional license of Windows Server 2012 allows up to two more virtual instances of Windows Server 2012 Standard, even though the physical server itself may have sufficient licenses for its processor chip count. Because Windows Server 2012 Datacenter has no limit on the number of virtual instances per licensed server, only enough licenses for the physical server are needed for any number of virtual instances of Windows Server 2012 Datacenter. If the number of processor chips or virtual instances is an odd number, the number of licenses required is the same as the next even number. For example, a single-processor-chip server would still require 1 license, the same as if the server were two-processor-chip and a five-processor-chip server would require 3 licenses, the same as if the server were six-processor-chip, and if 15 virtual instances of Windows Server 2012 Standard are needed on one server, 8 licenses of Windows Server 2012, which can cover up to 16 virtual instances, are needed (assuming, in this example, that the processor chip count does not exceed 16).
