Server Management Consulting and Support

Hyper-V is a new feature incorporated into Windows Server 2008 that provides the technology to build and manage an advanced virtualized server system. Hyper-V allows virtual machines to utilize unprecedented amounts of memory, high-powered multi-core processors, dynamic storage systems, and the latest high-speed network connectivity. With integrated tools for managing hardware and virtual resources, Hyper-V cuts the time required to configure hardware and software and replicate computing environments. Hyper-V offers advantages over Microsoft's Virtual Server 2005 by allowing the management of 32-bit and 64-bit virtual machines at the same time.

Hyper-V is hardware dependent and requires specific components:

• An x64-based CPU
• The x64-based versions of Windows Server 2008 Standard, Windows Server 2008 Enterprise, or Windows Server 2008 Datacenter
• Hardware-assisted virtualization, available with processors that support Intel VT or AMD Virtualization (AMD-V) technology
• Hardware Data Execution Protection must be enabled

Architecture of Hyper-V
Hyper-V's microkernelized hypervisor-based architecture provides a safer, more robust platform for managing virtual machines. The small-footprint hypervisor contains no drivers, which are instead hosted in the parent partition. Combined with the new IO sharing model, the Hyper-V architecture offers better protection than Microsoft's previous virtualization solutions.

Hyper-V allows you to take advantage of a new and enhanced feature set such as support for symmetric multiprocessing (SMP), dynamic storage solutions, support for up to 64 GB of memory per virtual machine, and the option for a minimal Server Core installation.

Hyper-V provides consolidation of a variety services which can be demanding on processing resources, such as Microsoft SQL Server. Hyper-V also supports third-party applications designed for previous versions of Windows or for Linux. As with all mainstream virtualization solutions, Hyper-V saves money by reducing the cost of server hardware and the costs of HVAC, utility bills, office space, and maintenance. Hyper-V also improves network availability, expandability, protection, and versatility.

Virtual machines powered by Hyper-V can utilize the security and capacity advancements offered by advanced server hardware. Server software designed for other operating systems such as Linux can run on the same hardware as Windows software and benefit from integrated, centralized management based-on Microsoft's familiar tools. This makes Hyper-V an economical alternative to setting up separate servers and managing them with diverse management utilities.

New Features of Hyper-V Server Virtualization Technology
Hyper-V incorporates an array of new and enhanced features engineered to improve network reliability, scalability, security, and flexibility. These features include:

• 64-bit native hypervisor-based virtualization
• Ability to run 32-bit and 64-bit virtual machines concurrently
• Uniprocessor and multiprocessor virtual machines
• Virtual machine snapshots, which capture the state of a running virtual machine. Snapshots record system state, so you can revert the virtual machine to a previous state.
• Integration of Virtual machine snapshot with Volume Shadow Copy Service
• Virtual LAN support
• Microsoft Management Console 3.0 management utility
• Windows Management Instrumentation interfaces for scripting
• Support for up to four virtual processors
• Support for 64 GB of RAM per virtual machine
• New efficient I/O architecture
• Support for Server Clustering and Network Load Balancing
• Microkernelized hypervisor architecture
• Minimal Server Core installation for improved security
• Granular VM management permissions, role-based security through Active Directory integration, and Authorization Manager
• Quick Migration and Cluster services
• Support for a variety of guest operating systems
• Support for all WHQL-certified drivers
