The purpose of this article is to share with you what kind of hard disk the cloud server uses. The editor thinks it is very practical, so I hope you can learn something after reading this article. Let's take a look at it with the editor.

Many users are not clear about the choice of the hard disk corresponding to the CVM, but how to choose a suitable disk system is a very critical issue. Here, let's introduce them separately.

1. WEB website server

Conditional users, it is suggested that you can use the SSD+ mechanical disk mode, the more popular SSD solid state disk in recent years, it is made of solid-state electronic storage chip array and the hard disk, and the traditional mechanical disk has a fundamental difference, the reading speed is very fast, than the traditional mechanical disk IUniver O performance is much higher, can SSD do business processing disk, and mechanical disk to do data backup disk from time to time. This not only improves the read and write performance, but also improves the data security performance.

2. Mail server

Ordinary file servers and other general business server rental, there is no too big IO requirements, it is recommended to use a mechanical disk, because its cost is relatively small, although the reading and writing speed is not as good as SSD, but it can also deal with normal website business problems.

3. Large database

Two ways are recommended, one is the SSD business processing disk, and the mechanical disk is used as the backup disk, because the SSD space is relatively small and the price is relatively expensive. If the data is very large, then there is a second solution, that is, the mechanical disk + disk array mode.

Disk array technology can greatly improve the read and write performance and data security performance of the hard disk, but it will sacrifice part of the hard disk storage space. At present, what is more popular is the RIAD5 mode, that is, 4 mechanical disks to do the array, which can get the use space of 3 hard disks, one of which is a hot backup hard disk. The cost is relatively low compared to SSD, and the performance is not much different.

4. Large game server

In the game, the performance requirements for IO are relatively high, so you can choose according to your own needs. The top matching mode is SSD multiple hard disks, and disk array technology is used to do our data storage. In this way, not only the IO performance is the highest, but the CVM security performance is also the highest, but the cost is also the highest, so you should choose carefully.

The above is what kind of hard disk the CVM uses. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
