All kinds of industrial rooms contain various integrated professional technologies such as construction, electrical circuit, network, and cabling installation. They gather and disseminate different information. Therefore, the good or bad environment construction of each computer room determines the safe and reliable operation of the equipment. , And whether the machine can make full use of the performance of the equipment. The equipment in the equipment room includes servers, storage, switches and other equipment. In order to ensure normal operation, the technical requirements of various types of equipment must meet the requirements. If they cannot be achieved or exceed the technical standards, the life of equipment will be shortened and the reliability of operations will be reduced. In order to avoid this situation, it is necessary to strictly control the environment of the equipment room. The factors affecting the environment of the equipment room include temperature, humidity, waterproof, fire prevention, anti-static and other factors. In addition to the need to ensure the equipment's own hardware and software requirements, the equipment can operate normally. In addition, it is also necessary to understand the impact of the environmental conditions of the equipment room on the equipment.
Temperature issues With the increase in equipment load, the heat dissipation problem has become the number one killer in the engine room, and the temperature has a large part of the relationship between the work efficiency of the equipment in the equipment room environment and the quality of work. Any electronic device has strict requirements on the temperature when it operates. Higher temperatures can result in reduced performance of electronic components, shorter service life, and lower insulation. Excessive temperatures can also cause server machines to fail. Lower temperatures will change the parameters of the capacitors, inductors, and resistors, indirectly affecting the server's operation. In addition, when the UPS is working in a high temperature environment for a long time, it will cause the battery to over discharge, and the battery life will be shortened; the UPS battery working in a low temperature environment for a long time will cause the battery discharge efficiency to drop greatly. These problems will affect the work and business operations. Can we grasp the temperature and humidity of the engine room in time?
Humidity issues Humidity has a great impact on the equipment. The air in the equipment room is humid and can cause rust on the metal components and connections of the equipment. And cause the circuit board, the connection device and the wiring insulation to reduce, serious may cause the circuit short circuit. When the humidity increases, the components or the surface of the dielectric material easily form a water film, causing “conductive paths†and “arc phenomenon†causing device failure, and when the humidity is too low, that is to say dry, the electrostatic voltage Will increase. Not only affects the working status of the equipment. But also affect the normal operation of operators and maintenance personnel. Can we prevent such problems from happening?
Leakage problems Leakage problems have always been ignored by computer room management personnel. Once leaks occur, if they are not stopped in time, they will cause incalculable losses to the equipment room: circuit short-circuits, damage to key equipment such as UPS and servers, and even fire. Can leak leaks be found in a timely manner to avoid these problems?
Air-conditioning problems Various air-conditioning systems configured to solve the problem of heat dissipation in the engine room, due to the lack of an effective self-test mechanism for failure, once a failure occurs, it will not only fail to radiate heat, but may also cause a series of computer room accidents such as water leakage and fire. occur. Can an air-conditioning system provide an effective monitoring mechanism?
Fire problems Smoke test is the last line of defense for the fire alarm system in the engine room. The lessons from numerous fire accidents in the engine room indicate that more than 90% of fire accidents can be avoided by installing smoke sensors, which can reduce or even avoid fires.
Effect of dust 1 When the dust in the air is large, the dust falls on the magnetic disk to scratch the magnetic head and magnetic layer. The head and disk gap theoretical calculation is 2-3wm, but the actual disk surface is not an absolute level, there is also swinging when rotating, the speed of the hard disk is generally 7200r/min (transfer), the actual gap between the disk and the head is very small, when turning Usually around 0.8-1pm. When the disk cleaning equipment is bad, it is vulnerable to more than 1wm of dust.
2 If too much dust is absorbed on the integrated circuit, the heat dissipation capability of the component will be reduced.
3 transmitter inlet, computer peripherals and UPS power supply and other equipment, with cooling ventilation and filtration equipment, when the amount of dust is too large, it is easy to plug the filter, so that the internal temperature of the machine is too high, and affect the normal operation of the machine Into the conductive dust, so that the insulation performance between components to reduce or short circuit, but also cause poor plug-in contact. 5 If too much dust is in the room, it will cause false alarms for smoke detectors. The dust content of the air in the foreign equipment room shall not exceed 1-0.75mg/m3 (mg/,-tcm), and the particle size of the dust shall not exceed 3wm.
The hazardous gas room may release toxic gases into the air due to the charge and discharge of the battery pack, including: sulfur dioxide, hydrogen sulfide, carbon monoxide, and ozone. These gases not only harm the body, but also react with water in the air to generate acids, alkalis, and salts. Corrosive substances such as integrated circuits and other sophisticated equipment cause great corrosion. This corrosion is often destructive. The conventional treatment method can first add an activated carbon filter after installing an air filter at the air inlet of the air conditioner to filter out bacteria in the air. Secondly, the sealing of the engine room is better, to ensure that there is enough positive pressure in the room, to prevent the intrusion of harmful gases.
Therefore, a good room environment is the basis for ensuring the efficient operation of equipment in the equipment room. The equipment room environment plays an important role in equipment maintenance. If the operating room environment does not meet the requirements, it will directly affect the normal operation of the system. Aging during acceleration, shortening equipment life. In view of the above, Beijing Yingchuangli and the engine room power environment monitoring system are highly reliable, stable and modular intelligent data center infrastructure monitoring systems for UPS, precision air conditioning, water leakage, temperature and humidity, security, access control, fire protection, smoke Sensors and other equipment, through communication and interaction, intelligent analysis, intelligent control, humanized display methods, so that data center operation and maintenance personnel in a timely manner to understand the health of the data center, and strive to create a new type of green energy-saving machine room.
