Today, the editor will share with you the relevant knowledge of what the server memory and data disk refers to. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article, let's take a look at it.

Server memory

If the memory is too small, the system process will be blocked and the application will become slow or even unresponsive; if the memory is too large, it will also be wasted. In Linux systems, physical memory and virtual memory are used. The use of virtual memory can alleviate the shortage of physical memory, but if the virtual memory takes up too much, the performance of the application will degrade significantly.

The larger the server memory, the larger the cache, and the faster it opens. If you do not know how to select memory, a simple method is recommended. Choose memory with CPU. For example, if the CPU is in 1 or 2 cores, there is only 2 GB in memory; if the CPU is in 2 or 4 cores, the memory can be in 4 or 6 gigabytes. If used in this way, the performance of the server is better.

Server data disk

The CVM has a total of two hard disks, one is a system disk, which is used to store system data. One is a data disk, which is used to store other data.

If a CVM is compared to a computer, the data disk of the CVM is equivalent to the D disk of the computer, and the system disk is equivalent to the C disk of the computer. When the computer reinstalls the operating system, the content of disk C is certainly gone, but the content installed on disk D is still there and will not be lost. Therefore, the function of the CVM data disk is that when the CVM initializes the system, the data of the data disk will not be lost with the system initialization.

If you are worried about the loss of the contents of the data disk, you can back up the data locally before reinstalling the system, and upload it to the CVM after installation. The general system disk uses the default 30G, which is enough to use. According to the demand, the data disk should be stored on the data disk as far as possible.
