The continued surge in data traffic is driving the data center into the "megawatt-hour." For telecom operators, it is a challenge and an opportunity to adapt themselves to the needs of business development, realize the green operation of the data center, dig deeper into the value of "data" and complete the turnaround from traditional "voice" to "traffic" management. Zhang Ziyang, chief architect of Schneider Electric, said in an interview with reporters recently that the data center will be able to make changes in the "megawatt-hour" times. The telecom operators can follow the trend of data center development and tap the " Data "value, at a lower cost, higher efficiency to create future-oriented data center. Big data spawned cold data centers "Telecommunication operators are the true owners of communication big data," said Zhang Ziyang. The rapid fall of big data applications is bringing new opportunities to the telecom operators' business transformation. Compared to BAT and other Internet companies, telecom operators are the real big data owners, whether it is generated in the mobile communications data, or WeChat, Taobao, Baidu platform generated Internet data, are inseparable from the core backbone of telecom operators network. From the type of big data point of view, can be divided into hot and cold data, hot data that is well-known financial data, consumer data, the value of these data has been the industry's attention. However, compared to hot data, cold data is the "biggest" of big data, accounting for more than 90% of the total data, mining and utilizing cold data will lead to a huge market that can not be measured, which naturally involves To a keyword - cold data center. What is a cold data center? Since cold data centers are the product of the big data era, they necessarily differ from traditional data centers. Zhang Ziyang said the cold data center must be real-time storage and backup of cold data, while cold data center volume is very large, there are orders of magnitude difference with the hot data center. These characteristics of cold data center, making it higher for the power supply system requirements. There are two major paths to storage technology in the cold data center today: one is the use of inexpensive Blu-ray burners and the other is the use of cold servers + storage. The former low power consumption, but can not do real-time analysis, the latter can implement storage, but the power consumption is huge. Therefore, whether there is a large capacity, high continuity of power supply system is to create a cold data center is the key. Currently, Schneider Electric has introduced the world's largest single modular 1600KVA UPS system. Cold data cold, meaning that these data may be shelved for a long time, making the operation and maintenance costs become the focus of cold data center operators. Zhang Ziyang believes that under the continuous reduction of operation and maintenance costs, "unmanned data center" will become a trend that will place higher demands on the data center DCIM layer and remote management and control levels. Under this trend, early warning will be an important capability for cold data centers. Early warning software from Schneider Electric can help cold data centers alert early in the event of an electrical contact aging or overheating, greatly improving operational efficiency, reducing costs and reducing the likelihood of risk. In the traditional data center construction, refrigeration system can not be ignored. "Compared to hot data centers, cold data center requirements for the refrigeration system is not too high," Zhang Ziyang said that because of cold data storage using blue light devices or cold storage devices for the environment itself, the temperature and humidity requirements are not high, so only focus on solving The hot dwell problem can use a variety of cooling technologies including triple cooling, ice storage or natural cooling on the wind side. The "two-polarization" trend in data centers The arrival of the "megawatt-hour" means that the data center will further develop in a large-scale direction. "In the future, the traditional small and medium-sized data center will die out, replaced by not a giant cloud data center, is a mini-data center" for the future trend of data center development, Zhang Ziyang made this judgment, in his view, in this In the "two-tier" trend, the giant cloud data center can meet the needs of massive data storage and processing, while the mini data center can meet the needs of the distribution of network peripheral content to support more applications to protect the user experience. Compared with the traditional data center, the construction of a giant data center will undoubtedly bring challenges. Zhang Ziyang said that after entering the megawatt-hour era, the measurement standard of the data center directly crossed from the previous "KW" to "megawatts". At present, China has built tens of thousands of square meters of mega-data with a capacity of over 20 megawatts Center is not a minority. For mega data centers, due to the scale and resource matching, the early design and specification design will have a far-reaching impact on the later stage. The evaluation of the quality of local personnel at the site selection stage determines the localization capability of future operators in the data center. Meteorological and hydrological research determines the application of energy-saving technologies in data centers; the investigation and assessment of address, traffic and security conditions determine the level of security in data centers; water and electricity prices and broadband resources determine the major construction costs for data centers . "This is a bit like a butterfly, and any small step can have a huge impact on the future," Zhang Ziyang stressed. Because of this, Schneider Electric has rigorous and scientific attitude over the years in the siting of data centers, environmental research, planning and consulting, and has accumulated a set of proven methods. The vigorous development of high-definition video applications, the edge of the network computing capacity requirements are increasing. As megatrends become the industry's focus, the concept of miniature data centers is starting to emerge. "In contrast to mega-data centers, miniature data centers focus on the content distribution at the end of the network, which will become a trend in the future as CDNs become more widespread," said Zhang Ziyang, who now includes leading vendors such as Schneider Electric Technology and product features, the introduction of a combination of monitoring and management, battery, air supply, cabinet power distribution cabinet mini-data center integration. In fact, in addition to technological innovations, business model innovation and efficiency gains will also provide an effective way to revolutionize the "megawatt" data center. "Life-cycle data center services have become a trend," said Zhang Ziyang. Currently, telecom operators are already exploring a package of turnkey engineering services that provide users with a full life cycle of design, construction and post-maintenance. In terms of efficiency improvement, it not only optimizes management and improves labor efficiency, but also increases the energy efficiency. This is the focus of the industry. Schneider Electric has introduced a series of technologies and products to help data centers improve efficiency in four major aspects of energy generation, distribution, storage and utilization, further reduce data center construction and operation costs, and realize benefits based on the protection of operators' investments maximize.
