The mainstream trend of global data center construction and development

Beijing, China, August 6, 2014, March 29, 2014, Shenzhen cloud base and China's first prefabricated modular data center were officially opened. The first phase of the data center project took less than four months from the mobilization of equipment in September 2013 to the successful completion of the whole project in January 2014. Among them, the most popular word is "fast", which just highly summarizes the advantages of prefabricated modular data centers

factory prefabrication is feasible

prefabrication modular data center follows the design and construction idea of modular data center, and modular deployment is undoubtedly the mainstream way of data center construction today; Secondly, it adopts the method of factory prefabrication, that is, to complete the assembly, connection and testing of the relevant infrastructure of the data center in the factory, so as to minimize the amount of work on the site of the data center, so as to shorten the construction cycle of the data center, improve the project quality, and also greatly reduce the cost

the data center of Shenzhen cloud base, located in the modern logistics center of Shenzhen Yantian Port Group, is said to be the first large-scale data center in China to be built by using the base factory prefabrication method. The total construction area of the data center is 60000 square meters, and it is planned to be completed in three phases within a few years. At present, the first phase of the project has been completed, with a total area of 5000 square meters, 680 existing cabinets, and 158 reserved

pedestal factory prefabrication method refers to dividing a large data center into appropriate modules, assembling and testing each module on the pedestal in the factory, and then transporting these modules to the data center construction site for splicing and installation. The traditional data center construction is a huge field project, which often requires dozens or even hundreds of people from different types of work to complete the construction of the data center. The pedestal factory prefabrication method turns a difficult data center project into a prefabricated product, which not only accelerates the construction speed of the data center, improves the quality, but also effectively reduces the construction cost

Hu Yin, CEO of Shenzhen Qianhai Tianyun Data Center Technology Co., Ltd. (hereinafter referred to as Tianyun data center technology), said that the transformation of data center construction from engineering to production is a major development trend of global data center construction. Yantian port data center is a benchmark of prefabricated modular data center. Its successful construction proves to the world that through factory prefabrication, a high-level data center that can meet the all-round needs of large data center users can be built. It provides reference and Enlightenment for the vast number of data center users and data center designers and builders

Shenzhen Yantian port data center phase I project has been put into operation. The operation of the data center business is in the charge of the professional service company under the cloud base. It is said that enterprise customers have rented the data center. Shenzhen Yantian port data center is no different from the crab eater. Its use shows that the prefabricated modular data center, which has become increasingly popular abroad, can also meet the needs of Chinese users

productization of data center engineering

rapid deployment, flexible expansion, high availability and low cost have always been the core requirements of users in the design and deployment of data centers. In today's China with the rapid development of cloud computing and big data, the above needs are more prominent, and modularization, factory prefabrication and other methods can obviously better meet these needs

in fact, factory prefabrication is not the patent of the data center industry. Hu Yin said that in the pharmaceutical industry, some large pharmaceutical enterprises also use factory prefabrication when building production lines and plants, that is, they produce the equipment or modules required by the product line first, and then install them on site. The same is true in renewable construction. One of the core businesses of broad air conditioning is renewable building. It built a building in the park within 15 days during the Shanghai WorldExpo, thanks to the way of factory prefabrication, that is, all components are produced in the factory, and then assembled at the construction site. Factory prefabrication can greatly speed up the construction of a project and reduce costs, so it has been applied in many industries. Due to some special application requirements, the data center industry may be more complicated than other industries when adopting factory prefabrication

in foreign countries, prefabricated modular data centers have only become popular in recent twoorthree years. Through in-depth research, especially the practice in the past year, Hu Yin has a deeper understanding of prefabricated modular data centers. He summarized the advantages of prefabricated modular data centers in the following four aspects

first, data center engineering is commercialized. This is the most profound impact and change that the prefabricated modular data center has brought to the data center industry. Yantian Port prefabricated modular data center will transform the construction of computer room engineering into customized products. The selection of external materials, internal equipment and assembly methods of products must undergo repeated optimization design, technical evaluation and system testing to ensure the delivery of reliable, safe and highly available data center products to users. The internal and external firmware of the product modular data center adopts a standardized structure, mainly including fire protection, lighting, maintenance sockets, equipment support structures, etc. These parts are all produced and assembled on the factory production line. A very complex computer room project that needs to be implemented in a distributed manner has become as simple as inserting building blocks, which greatly reduces the difficulty of construction and shortens the construction cycle. Usually, the construction cycle of a large data center is one and a half to two years, while the construction cycle of Yantian Port prefabricated modular data center is only three and a half months, which is enough to make Hu Yin and his team proud

second, function modularization. The modular data center product is to separate the relatively independent units in the data center infrastructure system, and carry out modular re integration. The module has its own system. Through the redundancy, backup and fault tolerance of various devices in the system, it can ensure that each module can output stably, so that the longitudinal axis of the sample coincides with the central line of the upper and lower clamps. These encapsulated modules are connected through limited cables and pipelines to form a complete data center system. The prefabricated modular concept makes the deployment of Yantian port data center more flexible, the expansion more convenient and the operation more economical

producing standardized modules is Schneider Electric's strength. Schneider Electric can provide refrigeration, power supply and distribution modules necessary for modular data centers. Schneider Electric is the main equipment supplier of Yantian port data center. Equipment including cabinets, distribution cabinets, UPS units and batteries, precision air conditioners, dense buses and medium voltage switches are all provided by Schneider Electric. Hu Yin said: Schneider Electric is our main supplier in prefabricated modular data centers

third, deployment is faster. The data center usually includes nine systems, namely, architecture, decoration, electrical, refrigeration, security, fire protection, fresh air, operation and maintenance, and management. In the design stage of the traditional data center, each system must undergo detailed design and reasonable research to determine the final implementation plan. The design cycle accounts for at least 1/3 of the overall construction cycle of the data center. Coupled with equipment selection and multiple reviews before project implementation, the construction cycle of the data center is further extended. Yantian Port Data Center adopts modular products that have passed optimization, testing and evaluation, greatly simplifying the design process and shortening the construction cycle

fourth, green operation. Yantian port data center takes green energy conservation as a key factor in the design process. Sometimes, the key equipment in the computer room, such as electrical and refrigeration equipment, is not fully utilized. This low efficiency caused by low load is the main reason for the low energy efficiency of traditional data centers. Following the design concept of modularization, Yantian port data center not only forms each module into a complete data center, but also abandons the practice of reserving 3-5 years of capacity in the traditional planning concept, realizing on-demand capacity expansion, thus improving the utilization efficiency of electrical and mechanical equipment and reducing the overall energy consumption

Yantian port data center also innovatively uses the cold wall of the refrigeration system developed by Tianyun data center in an environment where the hot channel has been partially closed. In the environment with closed hot channels, the use of cold walls can reduce wind speed, improve refrigeration efficiency, and even replace precision air conditioning. Some large foreign Internet enterprises have adopted the cold wall system. Hu Yin said that unlike standardized precision air conditioners, cold walls are not standardized products. They must be customized for the different needs of each data center project. In the fourth generation data center, the cold wall is gradually becoming a standard configuration, which can effectively reduce the pue value

prefabrication factory as the backing

before, the main product of Tianyun data center technology was container data center. However, the current container data center market in China is not mature and the demand is not strong. After taking over Tianyun data center technology last year, Hu Yin decisively adjusted the business. The container data center was retained as a product line, and the business focus of the whole company shifted to the construction of large data centers. Yantian port data center is the first t3+ level data center built by using advanced factory prefabrication after the transformation of Tianyun data center technology business. On the basis of this successful practice, Tianyun data center technology is also preparing to apply this method to the construction of Ningxia cloud base data center. After completion, this base will welcome international major customers such as Amazon AWS

some market analysis companies predict that in the next five years, more than half of the world's data centers, especially large data centers, will be built by factory prefabrication. Our current idea is to take advantage of the trend and take the construction of large data centers as our core business. Large interconnected enterprises and IDC are our target customers. Hu Yin said that factory prefabricated data centers are not limited by customer base, and can be used to build cloud data centers of interconnected enterprises as well as data centers of commercial enterprises. The essence of factory prefabricated data center is to turn data center engineering into a data center product. In this regard, Schneider Electric has done more to turn all components into standardized modules. In addition to standardized components, sometimes we have to provide customized solutions according to the specific needs of customers

factory prefabrication and modular data center design ideas complement each other. Each module of the data center is independent of each other. Even if there is a problem with one module, the modules will not affect each other. In the fourth generation data center, factory prefabrication and modular construction ideas have been accepted. We found that the modules of data centers are becoming smaller and smaller. For example, a data center built by Tencent in Shanghai has adopted micro modules. Schneider Electric also has strong strength in micro modules. Hu Yin said that factory prefabrication is very suitable for the rolling development of data centers. In the process of upgrading and capacity expansion, data centers can add new modules and more than a dozen machines at any time
