Southwest Communications Metropolitan Interconnect Center (IXC) and Data Center (IDC) are the first local Internet exchange centers in China, with a total investment of more than 30 million yuan. As the first local Internet exchange center in my country approved by the Ministry of Information Industry, the project is also one of the 15 key information construction projects identified by Chongqing in the "15th Five-Year Plan". According to the plan, after the center is completed, it will be able to solve the problem of local Internet access, thereby greatly saving information transmission time and operator relay circuit bandwidth; moreover, after the center is put into operation, it can also effectively solve the problem of local users in Chongqing having to exchange information through national Internet exchange centers in Beijing, Shanghai and Guangzhou. In this way, users such as Internet operators, schools, and scientific research institutions in Chongqing will no longer waste precious circuit relay bandwidth innocently because of exchanging data at foreign IXCs when exchanging information, and the Internet access speed will also be greatly improved.

1 Requirements for the power room plan

In order to ensure the steady operation of the IXC/IDC Internet Exchange Center, Southwest Communications conducted a detailed study on the network of the bearer center, and put forward strict requirements on the network core, or the "heart of the network" - the power room, believing that the power room must effectively solve three major problems.

First of all, the high availability of the AC uninterruptible power supply system and the environmental conditioning system is the core issue that the network energy system of the communication room must first solve. Among them, the purity of the electric energy is the key to ensure the high availability and high efficiency of the system, so when purchasing equipment, try to choose brand products of the same standard.

Secondly, a stable power source must be provided to ensure uninterrupted network operation. Because stability is the most demanding requirement, only by effectively solving this core problem can the network be guaranteed to operate 7×24×365, the UPS power supply system can work under the maximum MTBF state, and important loads can achieve "dual bus" power supply, ensuring that the bus or UPS system can be maintained without power outage, thereby avoiding "single point failure". At the same time, only in this way can more optional redundant backups be provided for the network, ensuring that the power supply can be switched without breakpoints when a failure occurs, and ensuring that the network does not need to be shut down during upgrades and expansions.

Finally, the operating environment must be reliable. The stability of the communication room is related to whether the entire telecommunications network can operate normally, and the environment of the room has become an indispensable factor. It is necessary to consider temperature, humidity, cleanliness and other aspects. Only in this way can we provide guarantees for obtaining the most reliable operating environment.

Southwest Communications is very aware of this, so in the construction of the IXC/IDC Internet exchange center, it placed the construction of the computer room and the uninterruptible power supply system in an extremely important position. After comprehensively considering various factors, Southwest Communications decided to adopt the design concept of a power integrated computer room. Since this project is the first local Internet exchange center in the country and has a demonstration significance, Southwest Communications not only has strict requirements on product quality, but also pays great attention to the diversified strengths of suppliers such as solution solutions and service guarantees. After several rounds of rigorous testing and investigation, Emerson Network Power's end-to-end integrated computer room network energy solution was finally selected, and it was undertaken by the company to build the entire project, taking full responsibility from the preliminary survey of the computer room, integrated solution design, to complete product integration, system debugging and commissioning, and final maintenance.

2 Implementation of the power room solution

In the solution design, as the only company in the world that can provide a full set of network energy products and end-to-end solutions, Emerson Network Power has adopted low-voltage power distribution solutions, AC uninterruptible solutions, DC uninterruptible solutions, computer room precision air conditioning solutions, and power environment centralized monitoring solutions to form an integrated IXC/IDC computer room power system overall solution. The solution mainly consists of the following four parts.

2.1 Low voltage power distribution system

The low-voltage power distribution system consists of four parts: automatic switching (ATS) cabinet, UPS input/output distribution cabinet, and air-conditioning switch cabinet.

From the solution point of view, the automatic switching (ATS) cabinet adopts the 1600A model to complete the automatic switching of dual input power supplies; the UPS input distribution cabinet is mainly responsible for distributing power supply to the "1+1" type 160kVA UPS redundant parallel system, air-conditioning units, lighting, fire-fighting and other equipment; the UPS output distribution cabinet is responsible for distributing UPS power to various IT equipment, emergency lighting, fire-fighting and other equipment located in the IDC computer room; the air-conditioning switch cabinet is responsible for the precision air-conditioning power distribution in the computer room.

2.2 AC Uninterruptible Power Supply System

Considering the current application status of the project and the future business growth, Emerson Network Power first configured a "1+1" type UPS redundant parallel system with an output power of 160kVA in the first phase of the AC uninterruptible power supply system. In the second phase of the project, another 160kVA UPS single machine was added to form a "2+1" type UPS redundant parallel system, bringing the total output power to 320kVA. In the third phase of the project, another 160kVA UPS single machine was added to form a "3+1" type UPS redundant parallel system, with a total output power of 480kVA.

2.3 Precision air conditioning system in the computer room

In the precision air conditioning system of the computer room, a total of 27 precision air conditioners are configured to ensure ideal environmental conditions. In actual application, 12 DME037E air conditioners are configured in the user hosting area, each with a cooling capacity of 8.6kW, of which 10 are working units and 2 are standby units. When the 10 air conditioners are working at the same time, they can provide a cooling capacity of 86kW; 8 DME037 air conditioners are configured in the major customer production area, one of which is a standby unit; in addition, a total of 7 units are configured in the power room and network room.

2.4 Power equipment and environmental monitoring system

The monitored equipment includes various low-voltage power distribution equipment, and the typical monitored parameters are: input parameters (including AC voltage, current, power, frequency, metering power, power factor), output parameters (including AC voltage, current, power factor), and low-voltage distribution panel status indication.

The solution introduces intelligent design, uses intelligent air-conditioning equipment and UPS power supply system as intelligent device access, installs UPS single battery monitoring system, and is also equipped with computer room environment monitoring equipment to monitor environmental conditions such as temperature, water immersion, etc.

3 Characteristics of the integrated power room

From the application point of view, the integrated power room of Southwest Communications IXC/IDC Internet Exchange Center is not limited to UPS power supply system, but also includes power distribution, DC power supply, air conditioning, power and environmental monitoring equipment. Through such an integrated design combination, it can provide services and reliable guarantees for the normal operation of the main equipment, and also achieve high reliability, high efficiency and high availability application effects.

3.1 Outstanding reliability and availability

Since the integrated system in the solution application adopts the Emerson network power system solution, the design of the system complies with the national design standards and the standards of the Ministry of Information Industry. In this way, the standards are unified in design, production and manufacturing, so as to maintain uniformity in technology and process flow, so that the equipment can be matched, so that all components in the whole system can play the best performance, obtain the purest electric energy, ensure the uninterrupted operation of key equipment such as IDC network equipment and data equipment, and avoid system failures caused by compatibility issues between various equipment. In addition, the selected equipment has good electromagnetic compatibility and electrical isolation performance, so as not to affect the normal operation of other equipment.

3.2 Easy maintenance and expansion

Since the main equipment adopts a modular structure design, it is very convenient for equipment maintenance and fault handling; one of the design cores of the end-to-end integrated network energy solution is the scalability of the network. In the system design, full consideration is given to the user's subsequent expansion, and a reasonable redundancy design is made to ensure that the application effects in the mid-term and early stages are consistent.

In addition, the entire system adopts intelligent design concepts. The system main equipment automatic switching switch, AC power distribution system, AC uninterruptible power supply UPS, DC uninterruptible computer room precision air conditioning, and power monitoring all adopt intelligent design. This eliminates the need to purchase a separate "smart interface board", making the entire network more intelligent and catering to the development trend of network energy intelligence.
