Generally, it is established in conformity with the GB Class A standard, to ensure the data center can work properly even in case of abnormal breakdown or normal maintenance, and the core business is not affected.

The infrastructure construction of data center room is a systematic project involving multi-disciplinary and multi-field knowledge, for instance, electrical engineering, electronics, building decoration, aesthetics, HVAC cleaning, computer, weak current control and fire protection professional, etc. The various systems are set up in accordance with the functional requirements, including the following eight major systems: building decoration system, power distribution system, air-conditioner fresh air system, lightning protection and earthing system, monitoring and management system, cabinet micro-environment system, fire alarm system and comprehensive wiring system.

1、Building Decoration System

Building decoration system is the basis of the entire computer room and mainly plays a role in dividing the function zone. According to users’ demands and device characteristics, the computer room area can generally be divided into main computer room and auxiliary computer room. The main computer room is reserved for placing equipment rack and servers.etc; The auxiliary computer room includes fiber optic room, power room, control room, air-conditioned room and operating room, which will provide the service for the main computer room. In addition, the decoration of data center room will adopt antistatic flooring, micropore return ceiling to ensure the room under the conditions of air tightness, no dust, no fire, anti-static and insulation etc. in order to provide favorable working conditions for the staff, and also the protection function for room equipment maintenance.

2、Power Supply and Distribution System

It is the power guarantee to ensure the computer room operation. Computer room load is divided into main equipment load and auxiliary equipment load. The main equipment load refers to computer and network systems, computer peripheral equipment and room monitoring system; the supply and distribution system of these parts are called “power distribution systems for equipment”, which require high quality of power supply, so UPS uninterruptible power supply will be adopted to ensure the stability and reliability of power supply. Auxiliary equipment load refers to air conditioning equipment, power equipment, lighting equipment, test equipment. Power supply and distribution system of those parts are known as “auxiliary power supply and distribution system”, the power supply relies on civil power directly. The room electrical construction should choose a high-quality cable, trunking and socket. The sockets should select UPS and waterproof sockets dedicated for major equipment with distinct mark. Non-glare high-class lighting should be chosen for the room.

3、Air Conditioning Fresh Air System

It is the guarantee for runningenvironment. Due to a large number of network and computer equipments are placed in high-density in the data center room, not only large amount of concentrated heat is produced, and it has high demands on the number and size of the dust in the environment, which puts forward higher requirements for air conditioning system. To ensure reliable operation of the equipment, the room needs maintain a certain temperature and humidity. At the same time, air conditioning is not enough when the room is sealed, you must add new air to complete the internal cycle. In addition, it must control the quantity of dust in the entire computer room, filtrates the new air, so as to achieve a certain degree of purification.

4、Lightning Protection and Earthing System

It provides a strong guarantee of the safe operation of the entire room. Room lightning is divided into direct lightning and inductive lightning. As for the lightning protection from direct lightning strikes, it will be completed by the lightning rod installed by the building; the room lightning protection (including the room power system and weak information systems) mainly avoid the lightning surges caused by inductive lightning and over-voltage by others. Earthing system is one of the key standards to measure a room construction quality. The earthing system of the room is generally divided into four grounded ways exchange, security protection, DC working ground and lightning protection. The room will adopt integrated ground solutions, the resistance of which should be less than 1 ohm.

5、Monitoring and Management System

6、Cabinet Micro-environment System

It is the real operating environment for IT equipment. In room construction, it is need to give full consideration of every rack in setting optimized power distribution, temperature monitoring system, cable management, combining rack, cooling, power, management and maintenance into an overall solution, which will provide reliable operation of the micro-environment for cabinet IT equipment.

7、Fire Alarm System

It is the shield safe operation of the entire room. The fire detection system needs to be equipped with a warm feeling, smoke detectors and infrared sensor, and most of the fire-extinguishing systems should adopt gas extinguishing. This requires that the steel cylinder room, fire control room and some pipes must be the planned before construction, so as to achieve full range of alarm, partition extinguishing to maximize the ability to fire prevention.

8、Integrated Wiring System

It is the way of network communications for the room. Integrated wiring system is a set of information transmission channel between the building or group of buildings setting in advance for the computer, communications facilities and monitoring system. It combines voice, data, image and other devices to each other, while the above apparatus can communicate with external data networks.

The most important systems among the eight large-scale infrastructure systems of data center are the air conditioning and cabinet micro-environment system, power supply and distribution system, and intelligent monitoring and management system. The pool level overall solutions of Sugon CloudBASE C4000 cabinet provide cabinets, air conditioning, power distribution and monitoring, the integration of four subsystems module integrated together to achieve comprehensive and state-of-the-art one-step solution with functions to meet the requirements and adapt to the new requirements of modern computing technology and business model on the room infrastructure energy efficiency, scalability and construction period.
