How many of the five best technologies does server maintenance know?

The core position of servers in applications, I believe that friends who can visit server channels should have a thorough understanding of them. How much do you know about server maintenance? Here, I will show you some things I know. First, I hope to give you a basic reference, and second, I hope it will arouse your awareness of server maintenance.

Server maintenance skills 1. Power Control

Although a server is not as fierce as an Induction Cooker, It is weaker than an ordinary PC, and it is also a heavyweight power user.

The most basic point of server hardware application is to achieve operational stability and continuity, while maintaining the operating stability of the hardware system, power stability is the foundation. In this way, when we deploy the power system in the IDC room, in addition to the sufficient supply of the Municipal Power of the server room, we also need to be able to cope with sudden power outages.

Assuming that a data center has 100 servers with an average rated power of 500 watts, a large UPS Power Distribution Cabinet equipped with 96 UPS dedicated high-specification batteries can basically ensure that after the mains supply is stopped, the machine runs normally for about 8 hours, and the actual application is about 6.5 hours ).

Server maintenance skills 2. Temperature Control

When most brands of servers on the market run, if there is no other control equipment, the average CPU temperature is above 60o C, and the internal temperature of the box is above 40o C, when the concurrency processing is busy, the above two scales may be able to improve by about 10-20 o C, which is quite different from the theoretical description in the manual. If the server continues to run for an hour at a time of busy concurrency, who knows what will happen next? Therefore, when we build a Server Runtime Environment, we must implement temperature control.

So how can we establish a temperature control environment? Use the air-conditioning system!

If it is an IDC or ISP data center with a large number of servers, you must set one or two centers to ensure that the main and large volumes of central air conditioners are required for daily temperature control, in addition, prepare one or two spare parts of the same specification. If one is an air conditioner with less than 10 parts, at least three vertical or outdoor wall air conditioners with a total horsepower should be prepared. Do not use indoor wall air conditioners to avoid serious consequences due to air leakage.) The room temperature should be controlled within 15-23O C.

In addition, if it is a large data center, it is best to have a temperature sensor for monitoring.

Server maintenance skills 3. Humidity Control

The humidity control of the server's surrounding environment is also very important.

Assuming that the server runs normally in a dry environment, it is easy to generate static electricity when it is exposed and rubbed around, especially around metal devices. The impact of static electricity on the server is clear to everyone. In case of carelessness, it is easy to cause current breakdown of important components such as capacitors or CPUs. The consequence is not only the system crash, this poses a great threat to the security of the operator.

China's geographical conditions are South Chao and North stem. In the data center in the North, we try to place a humidifier in the data center. In the South, especially in the data center on the first floor, we lay moisture-proof materials under the floor of the large data center, we 'd better place some water-absorbing infrastructure such as lime sandbags to prevent the equipment room from being too wet. The humidity in the data center in the North and South China should be controlled between 45-55%.

In addition, in the rainy days, it is best not to open windows for small data centers to avoid rainwater entering the house, causing unnecessary electric shock in the confidential environment of the data center's power facilities.

Server maintenance stunt 4. Fire Risk Control

Many people may think that fire control is irrelevant, because many facilities in the IDC are made of insulation materials. But in fact, there have been many machine room fire accidents. The plug-in board must select more formal, safe and reliable brands. It is best not to place the plug-in board for testing next to the water dispenser. Be careful when working on electroplating and soldering, it is best to go downstairs to solve the problem.

Of course, after solving human factors, we need to deal with unexpected environmental factors. It is best to prepare an independent alarm device for buildings without smoke suppression.

Server maintenance 5. Lightning Protection

Electronic devices are very sensitive to lightning sensing. If you do not pay attention to it, it may be dangerous.

Many buildings do not pay too much attention to lightning protection facilities. If the data center is in a building without a lightning rod, it is best to coordinate the property to install lightning protection equipment on the top floor of the building, direct the attacked lightning to the Earth. In addition, the UPS equipment is used to prevent lightning strikes and surges.

The article is very simple. I think it is too simple to give the beginners some experience.
