To reveal the Windows Server 2008 Virtualization
Different companies of all sizes have begun to realize that virtualization changes as a factor in the current scene. Server consolidation, energy efficiency, enhanced features and easier management and deployment of server virtualization for the shift, as well as the main virtual services have practical benefits.
Microsoft has seen the future of virtualization and Hyper-V began to seize the market (through its previous code name Viridian was you know, or by the previous brand name Windows Server Virtualization), the Beta version of it in this early on have been released, than expected in February 2008 to earlier releases. According to the company said, Hyper-V is the next generation of management procedures based on system (hypervisor) virtualization platform, and it will be integrated into the operating system, and allows you to dynamically increase the physical and virtual resources.
You may have learned from the whole concept of virtualization, but you may not be familiar with the specific details. Now we will see how Hyper-V is the work of its main advantages and when you can look forward to deployment in a production environment of these new features.
How does it work?
In order to understand the Hyper-V, first of all, consider its three main components: management procedures are (hypervisor), virtualization stack and the new virtualized I / O model. Windows is basically the management process used to create different partitions, and code examples of each virtualization will run in these partitions. Virtualization stack and the I / O provides the formation and function of Windows itself, as well as interactive and created the interactive features of different zoning.
All of these three components are the work of the order. Use are equipped with Intel VT-or AMD-V-enabled processors, server technology, Hyper-V can be interactive and management procedures, and management process is a very small software directly on the processor. The software will run the operating system and processor linked to the thread and the thread can effectively manage multiple virtual machines, a number of virtual operating systems, which are run on a single physical processor.
Because there are no third-party software products or drivers to install, you can almost guarantee full compatibility. Accompanied by an effective process management, you can in your virtual host of services, "hot swap" of resources. From the processor to memory, to the card, and then to additional storage media, you can increase the level of these devices to your machine without having to quit the service and any interruption of the user's conversation. You can also have a 64-bit client conversation, the conversation for the future use of 64-bit software is a big advantage. Virtualization you can migrate your system to save on the cost of deployment, and when you complete the migration, you can assess the needs in the end the number of physical host.
Virtualization is not just some of the ideas behind a copy machine, as well as reduce the cost savings, but also to ensure that services are available than those who do not use the number of server virtualization more. In this context, Hyper-V includes support for multiple clients clusters.
In addition, you can also run a number of Hyper-V components into the cluster of physical machines, so an example of virtualization from another host to resume, when the results occurred mainly when the host. Finally, you can be a virtual customer from one physical host to another stage transfer, without the need for time off to reduce the services and re-organizations, which normally will greatly limit the effectiveness of production services.
You can also use the same Windows Server 2008 on the new disk quota feature, which lets you have multiple locations in the cluster - for example, the east and west coasts in the United States or the world as a whole between different continents. You can do so, at the same time they do not need to have a single shared disk, which in the use of Windows Server 2003 operating system on the cluster is necessary.
In addition, you can Windows Server 2008 server core installation to achieve Hyper-V, and brought about by the use of such a deployment of an additional burden on the stability and. Of course, this will also lead to practical high-availability benefits of the object.
Then, when you can get Hyper-V brought about these benefits and enjoy these features do? Good news is that you can begin today to explore the product: the current in the Microsoft.com Web site, there is a Beta version of Hyper-V can be available for downloading. Microsoft Windows Server 2008 plans to go into production within 180 days of Hyper-V to stop the final build, and it will provide a number of Windows Server 2008 standard edition, you can choose with or without Hyper-V with Hyper-V. And Windows Server 2008 is expected to release in February 2008.
If virtualization in your structure, you are more concerned about time and money invested, you will be very pleased to learn that, when Hyper-V can be used when the official, Microsoft Virtual Server 2005 users can seamlessly migrate to the relative Hyper-V, and not have to worry about the loss of so far in the Virtual Server on the input. However, in some instances you need to understand the new hardware, because Hyper-V will need 64-bit hardware, and will not be a x86 version (32) in the release.
Hyper-V will be the history of Microsoft's virtualization an important next step. Through with appropriate hardware, you can enjoy the many unprecedented virtualization benefits.
