In the past, virtual server software sat on top of the network operating system and each guest session was dependent on many shared components of the operating system. Hyper-V provides a very thin layer between the hardware abstract layer of the system and the operating system that provides guest sessions in a virtualized environment to communicate directly with the hardware layer of the system.
Without having the host operating system in the way, guest sessions can perform significantly faster than in the past, and guest sessions can operate independent of the host operating system in terms of better reliability from eliminating host operating system bottlenecks. A technology enhanced in the core Windows Server R2 operating system is a power-management technology called core parking. Normally, when a multicore server runs, all cores on all processors run at the highest speed possible, regardless of whether the server is being utilized.
For organizations that need high capacity during the weekdays when employees are working, that means their systems are effectively idle during evenings and weekends, or more than two thirds of the time, yet consuming power and expending heat. With core parking, servers with the latest processors that recognize core parking protocols will shut down cores on a system when not in use. So, on a core server, if only 2 cores are needed, the other 14 cores are powered off automatically.
This dramatically improves power management and decreases the cost of operations of server systems. As much as there have been significant improvements in Windows Server R2 under the hood that greatly enhance the performance, reliability, and scalability of Windows Server R2 in the enterprise, Windows servers have always been exceptional application servers hosting critical business applications for organizations. Windows Server R2 continues the tradition of the operating system being an application server with common server roles being included in the operating system.
The various server roles in Windows Server R2 typically fall into three categories, as follows:. File and print services— As a file and print server, Windows Server R2 provides the basic services leveraged by users in the storage of data and the printing of information off the network.
Domain services— In enterprise environments running Windows networking, typically the organization is running Active Directory to provide centralized logon authentication. Active Directory continues to be a key component in Windows Server R2, with several extensions to the basic internal forest concept of an organization to expanded federated forests that allow Active Directories to interconnect with one another. These applications are initially made to be compatible with Windows Server R2, and later are updated to leverage and take full advantage of the new technologies built in to the Windows Server R2 operating system.
This book focuses on the Windows Server R2 operating system and the planning, migration, security, administration, and support of the operating system. Windows Server R2 is also the base network operating system on top of which all future Windows Server applications will be built.
