What is a Hyper-V Server?
Microsoft Hyper V Server 2008 is a virtualization product to virtualize a single stand-alone server through a hypervisor to handle multiple workloads. It offers a reliable and efficient virtualization solution that easily fits into user’s existing IT infrastructure so that they can increase server utilization and decrease costs.
What are the key advantages of Microsoft Hyper-v hosting?
You can easily virtualize a single server with a Hyper V hypervisor. It’s a very light product with just the Windows hypervisor and other kernel components to support virtualization. As the Microsoft Hyper-V Server 2008 is developed on Windows hypervisor, it is inherently more secure without any third-party device drivers in it.
It can be easily deployed on customers’ IT existing environments to further improve their existing patching, provisioning, management, and support tools and processes. ITPros can easily leverage their existing knowledge and skills with Microsoft virtualization products, as well as the collective knowledge of the community, minimizing any learning curve.
What are the new features of Microsoft Hyper-V Server 2008 R2?
The key new features in Microsoft Hyper-V Server 2008 R2 are:
Live Migration
Host Clustering
Support for up to 64 Logical Processors
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:
VM Chimney (TCP Offload) and VMQ support disabled by default
Jumbo Frame Support
Improved network performance via support for TCP Chimney and VMQ (specific hardware NICs required)
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 different disks
What is the difference between Hyper-V and Microsoft Hyper-V Server?
Hyper-V is a virtualization product using hypervisor for virtualizing Windows Server 2008. Microsoft Hyper-V Server is a hypervisor-based server virtualization product that allows customers to consolidate workloads onto a single physical server.
