Windows 2012

Windows Server 2012, codenamed “Windows Server 8” is a server version of

Windows 8 using new file system support called ReFS(Resilient File

System).

Advanced Features
Windows Server 2012 can switch between “Server Core” and “Server with a

GUI” installation options without a full reinstallation. Server Core – an

option with a command-line interface only – is now the recommended

configuration. There is also a third installation option that allows some

GUI elements such as MMC and Server Manager to run, but without the normal

desktop, shell or default programs like File Explorer.

Windows PowerShell has over 2300 commandlets, compared to around 200 in

Windows Server 2008 R2.

IPAM(IP address management: role for discovering, monitoring, auditing,

and managing the IP address) is used for the management and monitoring of

Domain Name System (DNS) and Dynamic Host Configuration Protocol (DHCP)

servers. Both IPv4 and IPv6 are fully supported.

Server Manager has been redesigned with an emphasis on easing management

of multiple servers.

By projecting a virtual NUMA topology into large virtual machines, the

guest operating system and applications such as SQL Server can leverage

their existing thread scheduler and memory allocation optimizations

Non-uniform memory access (NUMA) is a computer memory design used in

multiprocessing, where the memory access time depends on the memory

location relative to a processor.

The Active Directory Domain Services installation wizard has been replaced

by a new section in Server Manager, and a GUI has been added to the Active

Directory Recycle Bin.

Multiple password policies can be set in the same domain.

Upgrades of the domain functional level to Windows Server 2012 are

simplified; it can be performed entirely in Server Manager. Active

Directory Federation Services is no longer required to be downloaded when

installed as a role, and claims which can be used by the Active Directory

Federation Services have been introduced into the Kerberos token.

Active Directory in Windows Server 2012 is now aware of any changes

resulting from virtualization, and virtualized domain controllers can be

safely cloned.

Windows Server 2012, along with Windows 8, includes a new version of

Hyper-V.Each virtual machine in this version of Hyper-V can access up to

64 virtual processors, up to 1 terabyte of memory, and up to 64 terabytes

of virtual disk space per virtual hard disk (using a new .vhdx format).
Up to 1024 virtual machines can be active per host, and up to 8000 can be

active per failover cluster.

Windows Server 2012 includes version 8.0 of Internet Information Services

(IIS). The new version contains new features such as SNI, CPU usage caps

for particular websites,centralized management of SSL certificates,

WebSocket support and improved support for NUMA, but few other substantial

changes were made.
