How to choose the database server, I believe that many inexperienced people are at a loss about it. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

In the Internet age, having data means having value, and database servers are of great importance to any company. After understanding the importance of the server, how should the company choose the database server? What are the necessary conditions for these database servers?

One: hardware redundancy

For ordinary desktops, slightly important components cannot afford to be damaged. As long as there is a little damage, the machine cannot function properly, but the server is different. Servers above the departmental level generally have redundant services. and have the following advantages:

There are several CPU, one of which CPU is broken, and the other can keep working in most cases. Hard disk image hot backup. The data on the server for many applications, if finished, the loss may be huge! Hard disk mirror hot standby ensures that your data will not be affected when a hard disk is damaged, and the server will work properly.

The equipment is equipped with multiple sets of power supply systems and two or more external power supplies. In other words, a machine has two power plugs, and you can plug two plugs into the power of two different power providers. When a power supply goes wrong, the server can still work properly. Multiple power supply systems also ensure that when one of the server's power supply components is broken, the server can also use another set to work properly.

Second, high multi-tasking ability

The average personal computer generally uses a single CPU, while the server is often double CPU, or even 4CPU, which can handle twice to several times the number of concurrent threads. Moreover, the CPU of the server is generally better than the average personal computer.

Ordinary desktops are mainly used for personal operation, surfing the Internet, playing games, managing articles, and others. In general, no matter how much you play and how many programs you open at the same time, the number of active processes will not exceed 20 or 30. When a server has hundreds or thousands of people making certain work requests to the server at the same time, the server will have hundreds or thousands of threads.

Three: stability and huge amount of memory

The first thing the server needs to ensure is stability, so it uses memory with ECC (error checking and correction) function. Although this kind of memory will be slower than the memory we normally use, its stability is indeed commendable, that is, data is much less likely to go wrong in memory due to hardware reasons.

After reading the above, have you mastered how to choose the database server? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
