Windows 2008 Servers, which require no graphical user interface can be installed as the core. Only a minimal system is installed, which out-of-the-box is administered through a command line interface. Since only the required features are included, the footprint is smaller than a full installation of Windows Server. Fewer Bits & Bytes also means a smaller attack surface and thus less patches.
As a Server Core installation not the familiar Windows user interface is used, "are given) for the completion of the server configuration does not standard procedure (" Out-of-Box Experience. Instead, the initial configuration manually run with Command prompt tools, so the popularity of the server core keeps administrators in the unfortunately still quite limited. In order to show easier ways like a server faster and easier it will be put into operation, following a brief overview of the Server Core Management Tools.
Model-based virtualization host Virtual Server, which required running virtualization on top of your computer operating system, Hyper-V is a virtual environment that works directly on the hardware level, without exchanges with the operating system. Hyper-V architecture consists of a microkernel hypervisor, as well as parent and child partitions.
All versions of Hyper-V has one parent partition. This section controls the functions of the Hyper-V. From the parent partition running the console Windows Server Virtualization. In addition, the parent section is used to run virtual machines (VM), supporting streaming emulation of old hardware. Such VM, built on the ready-made templates that emulate the hardware, are analogues of VM, working with virtualization products on the basis of the host, such as Virtual Server.
Hyper-V offers more features than Virtual Server 2005 R2. Since Hyper-V only works on 64-bit platforms, the host system allocates up to 1 TB of RAM. Hyper-V does not limit the number of active VM: the maximum number determined by the capacities of the hardware host. In addition, VM Hyper-V are more scalable than VM Virtual Server. Hyper-V supports both 32-bit and 64-bit guest operating systems. Guest systems may use high-performance architecture VMBus, as well as get more RAM and CPU resources than offer Virtual Server. Technology, Virtual Server 2005 R2 does not support symmetric multiprocessing and has a limitation in the allocation of memory (up to 3.6 GB per VM). Hyper-V allocates for each VM to four virtual processors and up to 32 GB of RAM. To harness these opportunities fully, the host system must have at least four processing cores and more than 32 GB of physical RAM.
Hyper-V provides a new data storage technology. Support for Storage Area Network (SAN) allows you to download the VM and implement clustering interception refusal guest systems, and virtual servers. Package Hyper-V also provides data storage with access via the VM. With the help of technology Hyper-V can apply to the images of virtual hard disks without mounting the VHD image to the active VM. Hyper-V also allows you to use the service Volume Shadow Copy Service (VSS) for backing up VM. At the network level technology Hyper-V allows you to install a new virtual switch with support for the mechanism of Windows Network Load Balancing (NLB) to connect the VM and the various servers. In addition, Hyper-V allows you to make snapshots of active VM and provides an opportunity to make a return of virtual systems on any of the stored snapshots.
Hyper V on Windows Server 2008
Hyper-V is not installed by default with the system of Server 2008. To install the component Hyper-V using Server Manager from the Windows Server 2008. In the Start menu, select Programs, Administrative Tools, then click Server Manager. In the Server Manager add the role of virtualization. To do this, click Add Roles Wizard, and then Add Roles Wizard.
In the wizard Add Roles Wizard to mention the role of Windows Server Virtualization. Next, click Next and see the wizard screens, allowing to explore and configure Hyper-V. The first thing the wizard will explain that, you may need to configure support for virtualization in the BIOS. The program will link to the files Relief Services Windows Server Virtualization Online Help. Next you'll be prompted to specify the network connection that you want to associate with the virtual networks. By default, the wizard creates a virtual network for each actually installed network adapter. Next will be asked to confirm the information, and reboot the system
Systems technology AMD-V virtualization by default. However, if the system uses virtualization technology Intel-VT, will have to see the BIOS settings at boot time and make sure that virtualization is enabled. When you work with motherboards from Intel to press the F2 key during startup to view your BIOS. You can set the parameter Enable VT, to allow the processor to support virtualization. After the reboot screen Resume Configuration Wizard. Use it to finish adding the role of Windows Server Virtualization. The new role will be added to the container-established roles in Server Manager.
