Does Tencent have a dream? There may not be a single answer, but Tencent is definitely a product-driven internet company. Ma Huateng, chairman and chief executive officer of Tencent, said,

This year Tencent's construction of the Gui'an Seven-Star Data Center has passed the news. The total area of the Gui'an Seven-Star Data Center is about 770 mu. The tunnel area is more than 30,000 square meters. The construction area of the first phase of the project has reached 90618.57 square meters. Ma Huateng mentioned before.

Tencent today's largest data center

Before the growth of the business carried by Gui'an data center, Lei Feng's Tianjin data center, which is visited by the digital China Wanlihang team, is still the largest data center of Tencent. In May 2018, the number of servers in Tencent Tianjin Data Center exceeded 100,000, becoming the first single campus server in China to exceed 100,000.

Tencent Tianjin Data Center was put into operation in November 2010. It is the first fully self-built super-large-scale data center of Tencent and the largest completed data center in China. Tencent Tianjin Data Center has four buildings with a total floor area of 92,777 square meters. Among them, the second building is an office building and the other three buildings are all computer rooms. The construction time and the technology adopted are different.

  • Building 1 was put into operation in 2010, with a floor area of about 20446 square meters, 1300 design racks, a total design power consumption of 18MW, single rack power consumption of 8KW;

  • Building 3 was put into operation in 2014, with a floor area of about 38 971 square meters, 2 300 design racks, a total design power consumption of 36 MW, single rack power consumption of 6.5 KW;

  • Building 4 was put into operation in 2017, with a floor area of about 22516 square meters, 1200 design racks, a total design power consumption of 18 MW, single rack power consumption of 6.5 KW.

Tencent's previous three generations of data centres have been transformed by factory buildings (traditional)

Speaking of 100000 servers alone may not be very intuitive, we use the

Take Tencent's video business, which operates in the park's No. 2 office building, for example. If a two-hour Blu-ray HD movie is calculated at 30GB, it's equivalent to 160 million movies. It takes 320 million hours to watch, and a person can only see it in 36530 years. This is just the amount of data stored in a data center.

If all these hard disks were replaced with 12TB Seagate Exos X12 helium-sealed enterprise-class hard disks, the total storage capacity would triple, and power consumption could be reduced by 10% - 20%, or more. If the power of unit capacity is converted to power, it can be as low as 1/3.

As Tencent's largest data center today, such a large amount of data storage is very important to ensure physical security. Tencent has set up five protective zones, namely, infrared perimeter, park access control, building access control, building access control and biometric identification control, to protect Tencent's data center.

MDC micro module technology

As can be seen from the floor plan of the data center of Building 1 and 3, the functional area classification of building 3 is obviously less than that of building 1, because building 3 uses MDC technology, the air conditioning room, UPS room and battery room are cut off at the beginning of the design, and the corresponding functions are distributed in MDC, which is more flexible and efficient.

What is MDC? According to Tencent's official information, the Modular Data Center is a data center with micro-modules as independent units for factory prefabrication and rapid deployment, which can include a number of different functions, power micro-modules used together to meet business needs.

Tencent's customized TMDC=Frame

Li Quan, manager of Tencent Tianjin Data Center, told Lei Feng. com that there are many drawbacks in traditional data centers, such as energy-saving systems rely on architectural design, it is difficult to change; the overall delivery cycle is long (up to 6-9 months), the rack resource reserve often can not keep up with the speed of business growth; many construction units, construction quality is difficult. To control; due to one-time completion of the design, subsequent changes due to rapid changes on the server side are more difficult to adapt to the needs of poor flexibility; civil and IT construction tightly coupled. Civil engineering design and IT design need to be started immediately after land acquisition, the two parts of the design often do not match the schedule; UPS system and other potential accidents, but also reduce the efficiency of power conversion.

The data center using TMDC technology can solve the above problems to a large extent.

  • Energy-saving aspect: TMDC particle size is relatively small, easy to integrate a variety of energy-saving measures, thus playing a very good energy-saving effect;

  • Rapid Delivery: The fastest four-week delivery of micro-modules, rapid IT deployment capabilities make it possible to reserve large amounts of resources in a low-cost manner;

  • Quality controllable: through the prefabrication in the factory, greatly reduce the construction link, reduce the risk of safety accidents;

  • Life cycle: micro-module as a unit, can flexibly adjust the power consumption, capacity and other configurations; after the end of the server life cycle, micro-module as a unit can be decommissioned as a whole;

  • Civil construction and IT construction are separated. In the first stage, only the civil part is done, and the standard interface is reserved for the IT part.

  • The initial investment in Civil Engineering (less than 20%) is small, and the IT part is phased in on demand and accepted by stages.

  • High voltage direct current completely replace UPS to ensure safety and high efficiency.

The biggest advantage of micromodule technology is that energy saving TMDC also uses closed channels (5- 10%), interline refrigeration (


Simplified example of distribution architecture

Li Quan said that if a traditional data center, the original PUE (Power Usage Effectiveness) = 2.0, reasonable use of MDC technology after comprehensive energy saving about 24%, theoretical PUE can be reduced to about 1.5.

Power and heat dissipation on 100,000 servers is a huge expense, requiring manufacturers to pursue lower PUEs. A dual server with two Intel to Strong Gold 5118 processors (one of the best-selling strong scalable processor families in China's enterprise market) is used as a reference model. The full load power consumption is about 400 watts, and the annual power cost of 100,000 servers is 350 million degrees.

If PUE = 1.5, the annual electricity bill would be 525 million degrees; if PUE dropped to 1.2, more than 100 million kilowatt-hours would be saved each year.

Liquan shows the actual PUE data of Tencent Tianjin Data Center Building 1 and 3, it can be seen clearly that the energy-saving effect of the data center using MDC technology is obviously better than the previous generation in one year cycle, and the winter shutdown of the cooling machine in building 3 is as low as 1.2 PUE.

Tencent Tianjin data center

Tencent started early in the field of data centers. In 2006, Tencent rented a building in Shenzhen to try out the construction and innovation of data centers. In 2007, Tencent began the design and construction of the first 200,000-scale data center, which is now the prototype of Tianjin data center. Tencent began to build two 100,000-magnitude data centers in Shenzhen-Shantou Cooperation Zone and Shanghai Qingpu in 2014. Tianjin Data Center is built and operated independently by Tencent, while Shenshan and Qingpu data centers are large-scale data centers built in cooperation with operators.

According to international industry research

Tencent Cloud's market performance can not be separated from the support of data centers worldwide. Tencent Cloud operates 48 usable areas in 25 geographical regions. Geographical expansion is the primary task of Tencent Cloud's global layout. Tencent Cloud plans to launch more regions and usable areas in succession this year.

If Tencent Tianjin Data Center's 100,000 servers are all used for Tencent cloud services, considering that Tencent Cloud has begun to customize Intel's 61 series of processors with higher specifications for Intel's strong scalable processor generation, the server storage, network and other configurations for cloud computing are generally higher, one server The power consumption can reach 600 watts, and the expenditure mentioned above will be increased by half.

At the expense of hundreds of millions of dollars,

Gui'an seven-star data center will adopt T-block technology. T-block is the fourth generation data center technology developed by Tencent for two years. It looks like container body.

Different from the traditional container data center, T-block can be realized by container consolidation or steel frame splicing, which broadens the application scenario of T-block. On April 26, 2016, the Telecom Research Institute of the Ministry of Industry and Information Technology carried out a 24-hour uninterrupted on-load test on Tencent T-block. The daily power PUE was measured to be 1.0955. Of course, there is a deviation in the actual PUE.

Ma Huateng has talked more than once about Tencent's data center and cloud computing in various public places. The most popular word was at the 2010 Shenzhen IT Summit. Ma Huateng said that cloud computing would be possible to reach Avatar in a few hundred years or a thousand years. It was too early to do cloud computing. To sum up, the rapid transformation of Tencent cloud has caught the industry by surprise. The cloud computing business, supported by Ma Huateng, stands in the center of Tencent Group, asking for money and people, and investing 10 billion in five to 10 years, which is not an early investment.

Ma Huateng twice for Tencent Tianjin data center platform, Tencent throughout the data center landing ceremony he also attended many times, Tencent has already had a data cente
