Needless to say, the benefits of virtualization, I believe we all already know a lot. Most of the data center or are deploying virtual machines, or interested in the deployment of virtual machines, virtualization is a growing trend in the case, this phenomenon is inevitable, and who do not want their data centers with better performance, more low power consumption, better performance of it? Then as a data center management, in the face of the physical machine to virtual server migration, you considered what the problem occurs, how to solve these questions?
A good plan is half transplantation
By those who have achieved virtual survey: in the Transplantation of the virtual process, the program accounted for 90% of the entire work, the actual migration process only 10%. This work cutting wood with a knife is not wrong reason, a good plan is like transplanting a good knife grinding, knife a double reward.
First scheme is the choice of virtualization platform
Perhaps the biggest risk of virtualization is transplanted from the choice of virtualization platform, VMware, Xen, SWsoft, or Virtual Iron Software, and many other virtualization platform, which would you choose it? Maybe you choose the wrong platform to determine your entire transplant program errors, there are no deliberate smear virtualization platform which company will not do mean, just telling you the truth: to select the most suitable is right!
Also as virtualization platform independent software vendors leads (ISV) licensing support issues, as before the IT network of experts also reported that some manufacturers have not introduced ISV support for virtualization technology and licensing policy, as this problem may occur because ISV does not support or do not permit their application in a virtual machine running on the situation.
Compared with OS virtualization for server consolidation of aging, a dedicated application server and domain controller for server virtualization is a better choice. The platform includes VMware ESX Server, XenServer, and Microsoft Virtual Server R2.
OS virtualization platforms, such as SWsoft and Sun Microsystems Inc. Solaris Containers provide the most suitable for high-performance web applications, databases and file services.
Some virtualization platforms, such as XenSource or VMware ESX, lists a series of hardware can support them, recognize that this is very important. Therefore, in this, we need to check the hardware and application compatibility.
In addition, virtualization also estimated the impact on hardware and equipment, as well as analysis of the existing environment to determine the host virtual machine and physical storage location in the data center.
So, the choice of a virtualization platform, consider your operating system and applications, ISV support, and environmental performance every day.
Virtualization transplantation techniques
Collect system information, to prepare for the transplant and recovery, at least one month to collect system information, the ideal situation is for 6 months, which is to ensure transplant success.
Physical machine to virtual machine (P2V) migration application can be accomplished by manually transplantation, or by thermal transfer, broken image or a bare metal storage manner.
The author is a P2V migration proposal, the best way is to heat transplantation and manual transplanting. Because transplantation is a manually operated manually install the OS applications, by way of recovery from backup synchronize data, and do manual replication. The heat transplantation in 95% of the time the work of state, to prevent the occurrence of hardware failures, and product maturity, like VMware, LeoStream, Platespin and other companies have a very mature product.
In short, the improvement of application program availability, infrastructure flexibility, enhanced long-term hardware costs of the Jiang Di, lower power consumption and testing, training and Bushu of more simplicity of the Dai Lai these virtual interests and benefits of a good Du Xu Yao transplant programs and techniques to achieve!
