The new stand alone hypervisor from Microsoft is designed to further the efficiency of the virtualization technology. Today organizations require increasingly adaptive applications and technologies to streamline their IT operations and reduce costs.
The new Hyper V Server 2008 R2 has added features like live migration, an expanded processor and memory support for host systems.
There are several features of Microsoft Hyper-v 2008 R2 designed to improve its performance:
1. Available live support for migration.
2. Clustering support present.
3. Networking Enhancements:
a. VM Chimney (TCP Offload) and VMQ (specific hardware NICs required) support are disabled by default.
b. Support Jumbo Frame.
4. Performance Enhancements:
a. Available CPU Core Parking.
b. Core Parking permit Windows and Hyper-V to consolidate processing onto the fewest no. of possible processor cores, and suspends inactive processor cores.
c. Available Second Level Address Translation (SLAT) in CPUs . SLAT support for both Intel (EPT) and AMD (RVI).
d. Storage Add/Remove: (VHDs and Pass Through Disks)
e. enhanced performance for the VHD for dynamic and difference disks.
The new hyper visor has made it possible for IT admins to enhance their existing virtualized environment. It has tools for patching, provisioning, management and support services. The learning curve is not very steep for those familiar with the previous versions of the hypervisor. Over all, this is the next generation hypervisor designed for a better performance and output for your virtualized environment.
What is Hyper-V Server?
Microsoft Hyper V Server 2008 is a virtualization product to virtualize a single stand alone server through 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 Hyper V hypervisor. Its a very light product with just the Windows hypervisor and another 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 are 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 difference 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 the hypervisor-based server virtualization product that allows customers to consolidate workloads onto a single physical server.
What is virtualization?
With virtulization technique, partitions are created in one physical server to create several virtual servers. Each of these virtual servers can function as a standalone server and can be individually rebooted. Virtualization products like Hyper V from Microsoft have radically improved the output and performance of windows virtual hosting environments
What is Vmware workstation?
You can load this virtualization software on the Operating System like Windows XP. After that it is possible to create any number of virutal machines with the help of this software. Virtual machines created with the software have their own individual memory like a stand alone server. User can installl their preferable operating system on it. It will work freely with the help of master machine’s processer and memory. It must be a own IP address. If any cases it crashes then user can start again with the help of the software. User’s master machine will be safe. It is the one of the best and most popular virtulazation products.
What are the different types of virtualization ?
There are mainly three types of virtualization. Those are as follows :
Storage Virtualization :
As the name suggests, this virtualization method brings together the storage devices on a network to create one large storage. Since all the storage devices like hard drives are united, they are easier to manage through one central monitoring system. Network administrators can easily maintain the resources and detect any increase in demand for storage capacity. It also makes taking backups easier as all data is centrally stored.
Network Virtualization :
As with storage virtualization, network virtualization pools together all the network resources. This allows the administrator to easily allocate network resources to individual users according to requirement. Bandwidth is divided into individual units so that users can access all of the network resources like files and folders on the computer, printers or hard drives etc from their computer.
Server Virtualization :
When multiple virtual machines run on one server, they can perform a multitude tasks without extra load on the server processor or space. It also allows for mistakes and errors to be detected instantly because all the tasks are running in separate virtual spaces although they are on the same server.
