Server virtualization Green It's the most important

Green it. Commonly known as Green IT, also known as Green Computing, refers to the efficient use of computer and network resources of the habit. Energy and refrigeration have received the greatest attention in green IT solutions. The concept of green it is no longer a new gadget in the computer industry, in the modern society emphasizes is the sustainable development, when this idea with the present it profession unifies, naturally also has the pursuit green the power, according to the current domain development, the server virtualization is the most important.

Abstract server physical resources into logical resources, let a server become several or even hundreds of separate virtual servers, we are no longer limited by the physical boundaries, but let the CPU, memory, disk, I/O and other hardware into a dynamic management of the "resource pool", thereby increasing the utilization of resources, simplify system management, Implement server consolidation and make it more adaptable to business changes--------This is the virtualization of the server. This industry generally agreed with the concept of server virtualization, in fact, simply speaking is to integrate the server to save costs.

In China's current IT development process, the energy consumption is too high, has been a very serious problem, in foreign countries in the grasp of it energy consumption has risen to the law of the height, but in the domestic generally think that TI is to create value, ignoring the increase in intrinsic costs, Now a server three years consumes more power than the server at the time of the cost of procurement, if it is a low-end server. At present, the number of servers in China about 2 million, there is nearly a notebook computer or desktop computers, such a large user group has made us to the computer energy-saving considerations can not be ignored, the point of no delay. This not only to the user's own interests, but also related to the issue of social sustainable development.

According to a recent study by the Corporate Strategy Group (ESG), most enterprises generally believe that server virtualization will have a direct and significant impact on reducing the energy consumption of data centers. Its impact will be twice times the development of more energy efficient physical server technologies. In fact, server virtualization enables consolidation of the physical server environment, which means that the data center needs only a small number of physical servers to meet the needs of running an equal number of applications. But this is only the first step in the development history of server virtualization. The enterprise can also monitor the CPU usage or CPU energy consumption of the physical server, migrate the related virtual machine workload, and realize the energy-saving advantages brought by the server virtualization more fully. The comprehensive utilization of these technologies can provide important additional value for the user's application environment. How much energy the enterprise can reap from these solutions depends not only on power costs, CPU utilization caps, server energy consumption, but also on solutions and configurations chosen by the user. After the two processes mentioned above, I think server virtualization will not be "virtual".

The current cloud computing boom, server virtualization in the future is not going to go out of another road is still to be seen, then perhaps the work of server virtualization will have a dedicated person to manage, but the road to server virtualization, as long as the server in, virtualization must be done. In the future, server virtualization in the field of small and medium-sized enterprises may be less pressure, after all, there are clouds, just do not know whether the future SMEs can enjoy this treatment.
