In addition to Per Core licensing, replacing Per Processor licensing, SQL Server 2012 also introduced new virtualization rights. For SQL Server Standard Edition, the only method of licensing virtual machines is by licensing each individual virtual core (up to the 64-core technical maximum). For the new SQL Server Enterprise Edition – Microsoft’s top-of-the-line database software (replacing Datacenter Edition) – allows for the number of virtual instances equal to number of licensed cores. Thus, a dual-CPU, quad-core server – that is, eight (8) cores – can run SQL Server Enterprise Edition in up to eight (8) virtual instances.
