Shulou(Shulou.com)06/01 Report--

   Shanghai Terrestrial Information Network Co., Ltd. is a high-tech enterprise specializing in Internet private line access, cloud computing services, IDC server hosting and telecom data communication services. After 24 years of continuous development, it has grown into an excellent enterprise-level cloud server, server hosting service and cloud computing service provider for developers, government and enterprise users, financial institutions, etc., a company that provides a full range of cloud computing solutions based on intelligent cloud servers.

   established Yunhua data Center in 2006 to promote its own research and development of "triple play R & D platform". Before 2004, there was a bottleneck in the exchange of visits between the north and south regions of the Chinese network, and the problem of blocked communication was extremely serious, which indirectly affected the business development of many enterprises. In order to solve the problem of north-south intercommunication of small and medium-sized enterprises and improve their IT efficiency, ground communication company arises at the historic moment. We have solved all kinds of problems of north-south exchange of visits through dynamic BGP technology developed by ourselves. After that, through continuous technological upgrading, it became the first enterprise in Shanghai to put forward the concept of interworking among the three networks and obtained a national licensed patent. For more than a decade, DMC's data center products have been favored by banks, futures, third-party payment and other financial customers for their high availability, high reliability and professional team service ability. it has created a very high customer loyalty and lease renewal rate.

   2008-2011, Terrestrial spent a lot of money in Jiading Industrial Park to build a large-scale cloud data center, vigorously develop cloud computing. This is the second data center for cloud computing practice and landing, providing basic service capacity of four centers in Shanghai and strategic layout of Internet + services. At the same time, the company cooperates with domestic cutting-edge manufacturers to jointly develop cloud-based applications, such as hybrid cloud, private cloud, public cloud, security protection, CDN acceleration, etc., further broadening the service system. The international computer room standard ANSI/TIA-942 divides IDC into four grades: T1, T2, T3, and T4. The ground access data center meets the international A-class / T3 standards, docking telecom, China Unicom, mobile backbone network, 1500KW2 dual-channel city power access, Emerson high-frequency 300KVA3UPS, first-phase CUMMINS diesel generator, 1000KVA+500kva2, gas station priority fuel supply agreement guarantee, generator weekly inspection, monthly drill 99.99% continuous power supply guarantee. The building built in the data center can withstand magnitude 8 earthquake, has a variety of emergency plans, and the computer room has linked pre-release facilities to ensure the safety of the server.

Energy saving and environmental protection, building a green data center

   green data center is advocated by the country, and it is also the inevitable requirement that the data center develops to a certain stage. At the beginning of the construction of the data center, ground access aims to control energy consumption and reduce costs, and the PUE value of the whole computer room is controlled at about 1.5. In terms of construction, the outer wall of the building is fully enclosed, and the external wall is well insulated, which is not only thermal insulation and waterproof, but also safe and beautiful. Carrier fresh air system, Darren chiller + Yimikang precision air conditioning host system redundancy level: 2 (Nylon 1) horizontal air supply design, cold and hot passage design ventilation system to ensure indoor positive pressure, dustproof, temperature control range: 21mm 250C, air humidity range: 40% 55%.

Intelligent management to realize efficient operation and maintenance

As the    saying goes, a good data center depends on construction for three points and operation and maintenance for seven points. The daily operation and maintenance not only depends on manpower, but also depends on the intelligent support of the system. Therefore, ground access has also made great efforts in intelligent management. Provide 24-hour professional guard and operation and maintenance supervision, strict entry and exit personnel supervision and certificate inspection, anti-trailing access control system, VIP infrared control double protection, multi-directional video surveillance without dead corner.

Over the past 25 years,   , as a second-level telecom operator, we will always uphold professional, pragmatic and efficient management concepts, flexible and diverse service mechanisms, strive to build and enhance the brand value of the company, and enhance the core competitiveness of enterprises. Through reform and innovation, we adapt to the changing needs of customers and the market, while striving to create value with customers, we will also create more benefits for the society.
