In the present office of Suzhou Guo Ke Comprehensive Data Center Co., Ltd., there is a huge spherical building, which is still in the steel structure construction stage. According to Yu, director of the operation center of the National Science and Technology Data Center, it will be the overall exhibition hall of the company in the future. Although it is still a long time before the construction is completely completed, it can be clearly seen from the company's planning sand table that this building complex located on the bank of Dushu Lake will surely become a brand-new and beautiful landscape of Suzhou Industrial Park.

Yu said that due to the complexity of the spherical building structure, the building is still being debugged before other office areas are put into use. However, Yu obviously sold a pass here, because in a later visit, the reporter found that Suzhou Integrated Data Center Co., Ltd. was good at complex craftsmanship far beyond these difficult buildings.
The art of balance
The essence of China's ancient architecture lies in symmetry, which also reflects the psychological characteristics of China people's pursuit of balance, longing for peace and moderation. During the Shanghai World Expo, the China Pavilion was framed by a bucket arch, shaped by a bucket crown and roofed by a nine-square lattice, which was full of China charm. In addition, the cities in China often present a chessboard structure, which is symmetrical to each other, just like a nine-square grid for practicing calligraphy.
It is this beauty of balance that runs through Suzhou National Science Data Center. Although Gu Zonggen, general manager of Guo Ke Data Center of Sushi, said: "At present, the construction scale of most data centers in China is generally1~ 20,000 square meters, and our planned area reaches 52,000 square meters." However, the reporter found in the actual visit that such a huge data center actually occupies only about 30% of the computer room.
Suzhou Guo Ke Data Center Power System
Don't rush to lament such "waste", because there is a very important factor in it, and that is balance.
IT turns out that in the National Science and Technology Data Center, all IT main equipment and pipeline routing are designed according to two channels. In addition to power, refrigeration and network, even weak current systems, air conditioning equipment, telecommunication systems and diesel generators must have two channels as backup. This not only meets the primary standard of T4 certification, but also ensures the normal operation of the data center even in the case of a single point of failure, thus achieving 99.995% reliability for the end users.
Speaking of which, you may be curious about such a strict certification system. In fact, as early as the American standard TIA-942 "Data Center Communication Infrastructure Standard", it has been divided into four levels according to the "availability", "stability" and "security" of data center infrastructure: level 1, level 2, level 3 and level 4. How to define the industry standard layer classification de Nesite infrastructure performance whose level comes from the American standard Uptime Institute. In this standard, according to the engineering requirements and practice, Uptime Institute of the United States put forward the hierarchical system framework of site infrastructure. Aiming at the requirement that the key equipment of data center is expected to reach the "five nines", that is, 99.999% system application availability, this paper puts forward the corresponding availability hierarchy index of the computer room site infrastructure (power distribution, HVAC and other related systems).
Specific to the "four-level" data center, it refers to the ability to perform any planned activities without interrupting the critical load, as well as to provide site infrastructure capacity and its ability. This requires active distribution roads at the same time. Generally, in the dual power supply system configuration of S+S, the power supply system is represented as two independent UPS systems, and each system has n redundancies. The critical load involved in a system does not exceed 80% of N. In such a data center, all computer hardware needs fault-tolerant dual power input. Strict fault-tolerant testing enables the data center to maintain unplanned faults or operational errors without interrupting the process of the computer room.
Gu Zonggen said: "Although many data centers in China now claim to meet the T4 standard, there are actually many subtle but crucial differences. For example, electricity, we introduce two lines of 20KV commercial power from two different substations, and then enter the power distribution room of the data center through different lines. Some data centers are nominally two loops, which actually come from one substation, so once there is a problem in the substation, the normal supply of standby power cannot be guaranteed. "
High but not expensive
As we all know, the first thing to deal with when building a data center in China is the "electric tiger". For such a high-standard computer room of the National Science Data Center, the above-mentioned 20KV mains electricity is obviously far from enough. In this regard, Gu Zonggen first thanked Suzhou Industrial Park for its unique advantages.
As early as 16 years ago, when Suzhou Industrial Park officially announced its cooperation with Singapore, the two governments planned and deployed the park's infrastructure according to the standard 50 years ahead of the domestic standard, with very high requirements for other infrastructure such as electricity, refrigeration and communication networks. Gu Zonggen said: "Other domestic power grids are generally 1 10,000 volts, while ours are all 20,000 volts. At the beginning of the first phase of the project, we applied for two power tests of each 14500 kW, and later applied for 40,000 kW, which is impossible in ordinary cities. "
The National Science Data Center has an excellent power base, and it also uses Cummins diesel generator set in the United States for dual redundancy design. The first phase is equipped with 7 2000KW diesel generators and an independent oil depot, and the standby time of diesel can meet the continuous operation of the data center for 48 hours.
In order to meet the refrigeration demand for T4, Gu Zonggen said that in addition to setting up a 2,600-ton central water chiller, Suzhou Industrial Park also set up a large-scale municipal centralized refrigeration system next to the data center, and delivered chilled water to the data center through municipal investment.
Of course, as a third-party hosting data center, besides electricity and refrigeration, network performance is also the key to determine its service quality. Gu Zonggen has always stressed that at present, many domestic third-party data centers are living in the cracks of the operator's data center market. Therefore, in the early days of the establishment of the National Science Data Center, they established cooperative relations with China Telecom, China Mobile, China Unicom and Radio and Television. At present, it has multi-line core backbone network access of basic telecom operators such as telecom, China Unicom and China Mobile, and the core network equipment adopts CISCO-NEXUS 7000 series, all of which adopt dual redundant topology structure, forming a stable and reliable network system covering science parks, connecting the whole province and the whole country, and having the right to use 8 155M international circuits, which fully guarantees the international network demand of offshore outsourcing enterprises.

Although such a huge double redundant design framework is adopted, due to the innovative design of air conditioning system, computer room layout, power system and cooling system, the PUE value of energy efficiency coefficient is less than 1.6, which greatly improves the energy utilization rate of the system and effectively reduces the daily operating cost of the data center.
After talking about the resource advantages of so many national scientific data centers, the rental cost of national scientific data centers has become a problem that comes to the bottom. According to Gu Zonggen, the National Science and Technology Data Center has a total investment of 840 million yuan, with an initial investment of 570 million yuan. Is the use cost of such a data center with "luxury" equipment amazing? In this regard, Gu Zonggen cited an example: "At present, the annual rent of the data center established in Japan and Hong Kong according to T4 standard is about 200,000 yuan per square meter. In China, the annual rent of a data center that can meet T3 standard in Shanghai is more than 20,000 yuan per square meter, while we only need 1 10,000 yuan. I think it is not difficult to calculate this account with more than 10,000 yuan in exchange for the protection of T4 standard. "
Gu Zonggen believes that such high and inexpensive conditions of use can quickly win customers' interest in the data center. Facts have proved that by the end of 20 10, the revenue target of the company 1 10 million has been successfully completed. Next, they will strive to become a world-class commercial data center within 3-5 years, and can independently provide comprehensive data service solutions for 2,000 enterprises.
The future of the cloud
For the future development, the National Science Data Center will first focus on enterprises that have settled in Suzhou Industrial Park. In Gu Zonggen's view, these are their most potential customers. It is understood that the National Science and Technology Data Center will mainly serve three types of customers: high-tech small and medium-sized enterprises, government service agencies and ITO/BPO/ financial back-office services. In terms of product positioning, Zhou Su and Guo Ke divide products and services into three levels: Environment as a Service (IAAS), Platform as a Service (PAAS) and Software as a Service (SAAS).
Obviously, these three levels of services constitute the whole of cloud services. Speaking of cloud computing, Gu Zonggen said that they have accumulated a lot of successful experience in this field. "If I can't provide cloud computing services, but just a luxurious environment, I can't really reduce the IT investment of enterprises. Imagine that if customers buy a lot of IT systems and put them here, they will be eliminated and updated after three years, which is very unfavorable to the IT investment of enterprises. Therefore, in the construction process, we invested 30 million yuan in the cloud computing system. In the next two years, we will invest another 60-70 million yuan. " Gu Zonggen has repeatedly stressed that no matter whether IT is the "cloud" of hardware or the service that can eventually provide software, only by building these resources of cloud computing can enterprise customers dynamically use the IT resources of data centers on demand.

Speaking of cloud services, Fengyun Network, also located in Suzhou Industrial Park, is Guo Ke's "brother company". Fengyun. com has been doing SaaS service for 3 years, and it is also well-known in China. Gu Zonggen said, "Fengyun.com has made more than 1 ,000 products, with more than 1 ,000 users. However, because there is no large-scale data center, many end customers have doubts about the reliability of SaaS services provided by Fengyun. I think that after the National Science and Technology Data Center participates in cloud computing, it will enhance customers' trust in Fengyun's SaaS service. "
Suzhou Guo Ke data center security protection monitoring center
Talking about the future, Gu Zonggen said that IBM GTS Company was chosen to undertake the design and construction project of Suzhou Guo Ke Data Center Phase I because it valued IBM's 470 data centers with a total area of 800,000 square meters in the world and its experience in data center management and operation. This time, with the help of IBM, the certification of Uptime Institute is enough to illustrate this point, so the cooperation between the two sides will go further in the future. Gu Zonggen said with confidence: "In the next three years, we will join hands with IBM to build' excellent data center' and' innovative cloud service', and strive to build the largest disaster recovery center, cloud service center and IT outsourcing service center in Jiangsu Province and even East China."
Reporter's notes
Tell me about setting up a data center.
Just like the two sides of a coin, in the face of such a successful case, people always want to dig more into the difficulties and setbacks behind them. However, when the head of the National Science Data Center of the United States reviews these not-so-distant past events, the first thing worth remembering is some very subtle but interesting things.
"Since IBM is solely responsible for the overall construction of the data center, there is actually no big problem. However, before that, we spent some energy dealing with the civil engineering department. " Gu Zonggen explained with a smile: "As a general construction unit, they don't know what a data center is, so we need to do a lot of communication and explanation with them during the construction process. A project like data center is a production project, not an office building project we thought before. After completion, all the facilities and equipment are production-oriented equipment. In terms of civil engineering, we should consider the overall characteristics and characteristics of these equipment when building. "
Gu Zonggen told reporters: "Now many people are always concerned about the commercial operation or management cost of a high-specification and high-input data center. In fact, in our own view, the biggest challenge is how to make good use of this data center. After the design, how to make full use of its flexibility and modularity to meet the personalized needs of more high-end customers. Today, you see cabinets in many places arranged neatly. Maybe a quarter later, when we opened the second computer room, we didn't recognize it. High-end customers have many personalized requirements. How to meet their requirements and integrate these different requirements into our services at the lowest cost is our challenge. "
