Microsoft® Hyper-V™ Server 2008 R2
Product Details
Microsoft® Hyper-V™ Server 2008 R2 is a stand-alone product that provides a reliable and optimized virtualization solution enabling organizations to improve server utilization and reduce costs. Since Hyper-V Server is a dedicated stand-alone product, which contains only the Windows Hypervisor, Windows Server driver model and virtualization components, it provides a small footprint and minimal overhead. It easily plugs into customers’ existing IT environments, leveraging their existing patching, provisioning, management, support tools, processes, and skills. Some of the new key new features that are available in Microsoft Hyper-V Server 2008 R2 are live migration, cluster shared volume support and expanded processor and memory support for host systems.
IT Pros can easily to leverage their existing knowledge and skills with Microsoft virtualization products, as well as the collective knowledge of the community, minimizing any learning curve. In addition, with Microsoft providing comprehensive support for Microsoft applications and heterogeneous guest operating systems, customers can virtualize with confidence and peace of mind.

Microsoft Hyper-V Server 2008 Features and Benefits
Microsoft Hyper-V Server uses the same virtual machine model as Windows Server 2008 w/ Hyper-V enabled so there is no need to re-tool your management infrastructure.
Live migration: Customers can dynamically move virtual machines from one physical machine to another with no downtime.
Host clustering and Cluster Shared Volume Support
Processor Compatibility Mode for live migration– allows live migration across different CPU versions within the same processor family, (e.g.”Intel Core 2-to-Intel Pentium 4” or “AMD Opteron-to-AMD Athlon”) enabling migration across a broader range of Hyper-V host hardware.
Networking enhancements: Microsoft Hyper-V Server 2008 R2 has the following networking enhancements:
VM Chimney (TCP Offload) and VMQ support are disabled by default
Jumbo Frame Support
Improved network performance via support for TCP Chimney and VMQ (specific hardware NICs required)
Microsoft Hyper-V Server 2008 R2 has the following performance enhancements:
Hot Add/Remove of storage (VHDs and Pass Through Disks)
Second Level Address Translation (SLAT) processor support for both Intel (EPT) and AMD (RVI)
Core Parking
Improved VHD performance for dynamic and difference disks
VHD format: To move a virtual machine from Hyper-V Server to a Windows Server 2008 Hyper-V environment (or vice versa), simply export the virtual machine and import it on the other host using the standard management tools.
BitLocker support: Hyper-V Server can take advantage of BitLocker technology to encrypt a Hyper-V Server so that even if it is stolen and the hard disks are removed, the data is still safe because it’s encrypted. This is particularly useful for branch offices or environments where physical security is a concern.
Live Backup support: Hyper-V Server includes native support for Volume Shadow Services so that it can provide Live Backup of running virtual machines without downtime.
Flexible hardware support: Microsoft Hyper-V Server leverages the Windows Server driver model and is compatible with a wide variety of server hardware and driver support for newer peripherals such as 10 Gb/E.
Flexible Storage: Hyper-V Server offers flexible storage support, such as:
Direct Attach Storage (DAS): SATA, eSATA, PATA, SAS, SCSI, USB, Firewire
Storage Area Networks (SANs): iSCSI, Fiber Channel, SAS
Virtual Machine Snapshots: Hyper-V Server fully supports virtual machine snapshots.
VSP/VSC/VMBUS: Both products fully leverage the driver enlightened architecture (VSP/VPC/VMBus) for high performance I/O. There is no conversion when moving virtual machines between Microsoft Hyper-V and Windows Server 2008 w/ Hyper-V.
Hyper-V Server (Parent Partition) provides:
Support for systems with up to 8 physical processors
Support for up to 64 logical processors (See the Microsoft Hyper-V Server 2008 R2 FAQ for more information.)
Support for systems with up to 1 TB of physical memory
Support for up to 384 virtual machines
Hyper-V Server virtual machines provide:
32-bit (x86) and 64-bit (x64) virtual machines
Up to 4 virtual processors per virtual machine
