More servers, more demand, more cooling costs, increase more network devices, power increase ... ... telecommunications networks grow, the energy consumption is also growing. The introduction of IT in the telecommunications room virtualization technology is a hot topic in recent years, better centralized management of resources and higher efficiency it was a lot of people called "the green data center's economic engine." However, the revolutionary technology will inevitably bring pain, cost, energy consumption and so on, virtualization technology in the telecommunications room of IDC is not necessarily perfect.
Recently, the market research firm Gartner released a survey, 45% of respondents are expanding or planning to expand in the next two years, data centers, while 43% of the respondents planned data center consolidation. In a traditional data center, 35% to 50% of the electricity used for cooling. If the best strategy to run it, this proportion can be further reduced. End to end virtualization technology is a business that can profoundly affect the life cycle of IT infrastructure management at all stages of the IT strategy, it can drive the entire organization-wide higher IT efficiency, flexibility and cost savings.
From the accelerated application deployment to ensure that the systems, applications and data continuously available, to avoid rebuilding the server to shut down the server and desktop development environment for testing and deployment, to ultimately reduce risk, reduce costs and improve flexibility of the entire IT environment nature of virtualization technology has a strong ability to transform IT infrastructure, from data center to the desktop. Virtualization will be the operator business infrastructure and operations affecting one of the largest technology, it will change the operator's IT management model, including the way the system architecture and how to introduce a wide range of telecommunications services and determine the tariff policy. At present, 3G and all business operations to the communications industry, IT application has brought tremendous opportunities for development, virtualization technology has become the choice of many operators, eager, from the several existing typical deployment of view, virtualization technology not only to achieve the IT system of efficient, flexible and balanced low-cost and green IT to achieve important goals such.
All business operations of the times, IT systems and communications products, network, further integration of business, research and development and also the explosive growth of business data, server management costs and application of number and the number of linearly increasing relationship, resulting in tremendous pressure on IT management and cost. How to more effectively manage the data center to facilitate data set, reducing the cost of IT assets and management, how to use limited resources to invest in better business results, improve business efficiency and availability, as IT competent operators urgent problem. Through virtualization technology, is expected to solve these problems and realize the concept of green IT.
However, server virtualization, maximizing server efficiency, but also brings functional consumption. Application virtualization efficiency vary widely, and some can be close to the original run of the efficiency of the physical environment, while others are inferior to the level of end-users are unacceptable. Those who like the system or Microsoft EXCHANGE database applications, require large quantities of I / O and memory resources are not suitable for the implementation of virtualization technology.
In addition, to the storage virtualization will bring some potential dangers. As many candidates running virtualization in a distributed X86 system, so it is easy to forget that more centralized architecture of virtual resources, the possible impact. For example, the storage array can not handle the work load: the throughput too much, too many I / O. If the SAN storage array to cause paralysis and problems, each virtual machine will be adversely affected.
