Core Infrastructure

Windows Server supports the core infrastructure services required to run your network. As Windows Server has matured, so have the included roles and features. Windows Server 2008 maintains and enhances the core infrastructure services that have always been part of Windows Server, providing a solid foundation for your business.  Click on one of the Core Infrastructure roles to learn more:

What’s new in Windows Server 2008 R2?

Windows Server 2008 R2, builds on the award-winning foundation of Windows Server 2008, expanding existing technology and adding new features to enable IT professionals  to increase the reliability and flexibility of their server infrastructures. New virtualization tools, Web resources, management enhancements, and exciting Windows 7 integration help save time, reduce costs, and provide a platform for a dynamic and efficiently managed data center. Powerful tools such as Internet Information Services (IIS) version 7.0, updated Server Manager and Hyper-V™ platforms and Windows PowerShell version 2.0 combine to give customers greater control, increased efficiency and the ability to react to front-line business needs faster than ever before.

Leveraging Sophisticated CPU Architectures

Windows Server 2008 R2 is the first Windows operating system to be offered for only 64-bit processors. With customers being unable to purchase a 32-bit server CPU for over two years, the performance and reliability advantages to moving to this architecture were too beneficial to ignore. Additionally, Windows Server 2008 R2 now supports up to 256 logical processor cores for a single operating system instance. Hyper-V virtual machines are able to address up to 32 logical cores in a single host. These improvements not only guarantee more bang for your server hardware buck, but also offer better reliability with fewer locks and greater parallelism.

Increased Operating System Componentization

Microsoft introduced the concept of server roles to allow server administrators to quickly and easily configure any Windows-based server to run a specific set of tasks and remove extraneous OS code from system overhead. Windows Server 2008 R2 further extends this model with support for more roles and a broadening of current role support, like the addition of ASP.NET within IIS 7.0.

Roles have been refined and feature sets redefined as customers have expressed desires for certain capabilities in popular scenarios. The Server Core installation option is an appropriate mention here with new (and much demanded) support for PowerShell scripting made possible by the addition of the .NET Framework to the list of server roles supported in the Server Core installation option.

Improved Protection of Intranet Resources

The Network Policy Server (NPS) is a Remote Authentication Dial-In User Service (RADIUS) server and proxy and Network Access Protection (NAP) health policy server. NPS evaluates system health for NAP clients, provides RADIUS authentication, authorization, and accounting (AAA), and provides RADIUS proxy functionality.

NAP is a platform that includes both client and server components to enable fully extensible system health evaluation and authorization for a number of network access and communication technologies, including:

  • Internet Protocol security (IPsec)-protected communication

  • 802.1X-authenticated access for wireless and wired connections

  • Remote access virtual private network (VPN) connections

  • Dynamic Host Configuration Protocol (DHCP) address allocation

  • Terminal Service (TS) Gateway access

Improvements in Backup and Recovery

Backup and recovery features are very important for the continued operation of the services and applications running on Windows Server 2008 R2. Windows Server 2008 R2 includes a number of improvements that are related to backup and recovery, including improvements in:

  • The Windows Server Backup utility.

  • Recovering from total failures of disk volumes by using LUN synchronization.

  • Integration with System Center Data Protection Manager 2007.

Improvements in Full Volume Recovery

Windows Server 2008 R2 includes support for LUN resynchronization (also known as LUN resynch or LUN revert). LUN resynchronization creates hardware-based shadow copies that allow you to recover a volume from an existing shadow copy of the volume.

LUN resynchronization is a method for quickly restoring volumes that leverages the capabilities of storage arrays (such as SANs).  This allows you to create shadow copies of entire LUNs and then restore from those shadow copies (using the inherent snapshot or copying features in the storage array). You can use LUN resynchronization to help you recover from data loss or to help quickly create duplicates of productions LUNs for use in a storage environment.
