Virtualization is one of the fulcrum

As the financial turmoil swept across the globe, people began to pay more attention to cost. While controlling the investment budget, more enterprises began to pay attention to energy saving and environmental protection. At such a time, all aspects of the links are more profound experience of this, and green it, energy conservation and environmental protection, virtual technology and so on are unprecedented hot up, recently PChome News center reporters visited the "virtualization experts" called VMware Company, In the current industry focus on the topic with the VMware Greater China Technical Director Mr. Zhang Zhenlen in-depth communication.

Reporter asked about the current situation of the unprecedented high virtualization technology, VMware Greater China Technology director Zhang Zhenlen that the rapid development of virtualization technology has two reasons: first, in recent years, PC server in the domestic application of a sharp increase in domestic ownership of thousands of or even tens of thousands of servers IDC also began to emerge, After the data center has reached this size, the original architecture and management will face great challenges, so today's majority of users in the server to dozens of units, hundreds of more than the scale, will consider how to effectively manage, and virtualization can effectively solve the number of PC server rapid expansion problem; In addition, the rapid development of hardware, dual-core, quad-core or even six-core CPU drive, making the server's memory expansion capacity, and virtualization technology can help users greatly improve the utilization of server resources, and reduce TCO cost.

With all the people "green" vigorously advocated, the virtualization of this quite backstage technology, has moved to the foreground, and become the realization of "green it" key technology, can be said that virtualization is the realization of "green it" the main technical means. As a result, many users of virtualization is the "God". Although this is not the answer, from the current application of the current situation, users have effectively benefited from it.

In fact, from the principle of virtual technology virtual is the instruction set. All it devices, whether PCs, servers, or storage devices, have one thing in common: they are designed to perform a specific set of instructions, which form a set of instructions. For virtual technology, "virtual" actually refers to these instruction sets. There are many different types of virtual machines, but they have a common theme that simulates the concept of a set of instructions. Each virtual machine has a set of instructions that the user can access, and the virtual machines do the work by "mapping" these virtual instructions to the actual instruction set of the computer.

When "virtual" becomes a reality, its benefits are also obvious: to consolidate server resources, reduce the total cost of ownership of the system, to serve those who want to use the server resources, but do not want to buy the server users, to improve the system's resource utilization, to provide monitoring of the operating system, Provides load balancing of HA support and resource usage, simplifies work to meet new application requirements, and helps reduce operating system dependencies on hardware platforms.

Our Status:

In our life, "green" in the people's mind is more and more important. To go to the supermarket to buy things, more and more people tend to buy food with "green" label. Whether it is vegetables or oil, rice, "green" label, it represents the rest assured, healthy, non-polluting.

Now, "green" has spread to our work environment. From green products, green data center, to now advocated green enterprise, green it, "green" is more representative of energy saving, emission reduction, environmental protection, reduce costs. In particular, the sudden global financial crisis, "green" has become a focus of various industries, users. Maybe it can help us through the winter.

This wonderful wish is beyond our consideration. At least one set of numbers can tell us how important green is.

• Some statistics and market research institutions reported that the current global server installed capacity of 35 million units, the annual server consumption of electricity costs is about 50% of the cost of procurement server, about 29 billion U.S. dollars;

• The cost of global energy consumption has accounted for the 30%~50% of operating costs consumed by IT industry;

• According to the calculation, the total power consumption of China's IT products in 2007 between 30 billion ~500 million kwh, almost equivalent to the Three Gorges power generation total;

......

Therefore, "Green it" is definitely not a slogan, but a real goal. But building green data centers, or green businesses, is not as simple as planting green vegetables. Behind it is the need for advanced information technology to support. One of the virtualization technologies, its focus on the "green it" par.
