B V A
I recently saw some interesting information out on the web on Windows Server 2012 and wanted to make sure everybody understands our licensing changes.
The Windows Server 2012 product line-up has been streamlined and simplified, making it easier for customers to choose the edition that is right for their needs:
Datacenter edition for highly-virtualized private cloud environments.
Standard edition for non-virtualized or lightly virtualized environments.
Essentials edition for small businesses with up to 25 users running on servers with up to two processors.
Foundation edition for small businesses with up to 15 users running on single processor servers.
Determining the number of licenses for Datacenter and Standard editions
The packaging and licensing structure for Windows Server 2012 Datacenter edition and Windows Server 2012 Standard edition has been updated to simplify purchasing and reduce management requirements. Each license covers up to two physical processors on a single server. The minimum number of licenses required for each server is determined by the number of physical processors. For Standard edition you can add more virtual instances by assigning additional licenses to the server (two incremental virtual instances are added per license).
A consistent processor-based licensing model that covers up to two physical processors on a server.
Windows Server 2012 Essentials edition and Windows Server 2012 Foundation edition remain unchanged.
Server-based licensing model – Foundation is for single processor servers and Essentials is for either one or two processor servers.
CALs not required for access – Foundation comes with 15 user accounts and Essentials comes with 25 user accounts.
Transitioning to the new licensing model
Windows HPC Server Suite
a) Windows Server 2012 Datacenter covers up to two processors per license, whereas Windows Server 2008 R2 Datacenter only covers one processor per license.
b) The grant provides you with an additional Windows Server 2012 Standard edition that you can use while maintaining rights to run your current Windows Server HPC edition, Microsoft HPC Pack Enterprise or Web Server licenses.
c) Window Server HPC edition and Microsoft HPC Pack Enterprise will receive a 2:1 (d) ratio of Windows Server 2012 Standard.
d) For these grants you will round up to the nearest whole number to determine the appropriate entitlement.

One of the better, succinct, explanations of the Server 2012 licensing model. Thanks for sharing.
Windows 2008 Enterprise licenses costs 3 times Windows 2008 standard. Nevertheless 2008 Enterprise with SA grants you two (2) Windows 2012 standard licenses.
Yet another little scam. Trying to exchange two 2008 enterprise licenses with running SA for one (1) 2012 datacenter license ? No way. While -2008- pricing is the same.
Microsoft SA, just say no..
