Windows Server 2012 start screen

Windows Server 2012 (codenamed Windows Server 8) is the sixth release of the Windows Server series of operating systems. It is the server version of Windows 8, and is the successor to Windows Server 2008 R2 and the predecessor to Windows Server 2016. It was released to manufacturing on August 1, 2012, and to the public on September 4, 2012.

Notable new features and improvements include:

Windows Server 2012 will be available in only 4 editions:

  • Foundation - Limited to 1 CPU and limited connections, AD must be forest root. Available through OEM only
  • Essentials - Limited to 2 CPUs, higher limits than Foundation. Available through Retail, VL and OEM.
  • Standard - Adds Hyper-V, Server Core, ADFS, and uses CALs. Available through Retail, VL and OEM.
  • Datacenter - Unlimited virtualization rights. Available only though VL or OEM


System requirements

Microsoft has indicated that Windows Server 2012 will not support 32-bit (IA-32) or Itanium (IA-64) processors,[1] but has not officially released any other system requirements, except for the Release Candidate. The following system requirements are for the Release Candidate, and are subject to change in the final release.

Minimum system requirements for Windows Server 2012 Release Candidate [2]
Architecture x64 (64-bit)
Processor 1.4 GHz
Memory (RAM) 512 MB
HDD free space 32 GB (more if there is 16 GB of RAM or more)

Upgrades from Windows Server 2008 and Windows Server 2008 R2 are supported, though upgrades from prior releases will not be supported.[2]

Editions

Windows Server 2012, unlike Windows Server 2008 R2, will have only four editions - the Enterprise, Small Business Server, Web, and HPC editions do not exist.[3][4][5][6]

  1. 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).
