How to choose the server hardware configuration? Is the higher the configuration the better?

For a computer, the server hardware configuration is very important, which affects the use and running status of the computer. We know that the higher the storage capacity of the computer, the better. The higher the storage capacity, the faster the computer runs and the better the experience. Every time you mention the server hardware configuration, the first thing that comes to your mind is the performance of the CPU. The performance of the computer CPU plays a key role in the operation of the computer. You should also pay attention to the various parameter settings of the CPU when purchasing. The following Xinwang will introduce what is included in the server hardware configuration and how to choose it.

1. What is a server?
A server is a type of computer that runs faster, has a higher load, and is more expensive than a normal computer. The server provides computing or application services for other clients (such as PCs, smart phones, terminals such as ATMs, and even large-scale equipment such as train systems) in the network. The server has high-speed CPU computing power, long-term reliable operation, powerful I/O external data throughput and better scalability.

2. What are the server hardware configurations?
1. CPU
Generally speaking, the more the number of CPUs and the higher the main frequency, the better the performance of the server will be. In the actual test process, if the CPU usage is kept low under high pressure, then the CPU resources can basically meet the server requirements.

This situation is actually a bit of a waste of CPU resources. The ideal situation is that the CPU utilization is relatively low when the pressure is not high, and the CPU utilization remains at 60%-70% after the pressure is on. Most CPUs can only run one thread at a time, but a hyper-threaded processor can run multiple threads at the same time, and we can use the pre-processing hyper-threading feature to improve system performance.

Although hyper-threading technology can execute two threads at the same time, it does not have independent resources like two real CPUs.

2. RAM
The size of memory is also an important factor affecting server performance. If the memory is too small, the system process will be blocked, and the application will become slow or even unresponsive; if it is too large, it will also be a waste.

The Linux system uses physical memory and virtual memory. Using virtual memory can alleviate the lack of physical memory, but if too much virtual memory is occupied, the performance of the application will be significantly reduced.

3. Internet Broadband
The size of the network bandwidth limits the traffic between the client and the server. Compared with other hardware resources, the network bandwidth is more expensive. This requires us to reasonably estimate the server’s server capacity and the required bandwidth resources.

4. Hard disk
In the past, hard disks were mostly operated mechanically, which was mainly reflected in the process of finding tracks before hard disk reading and writing. The size of the read and write cache that comes with the hard disk is very important for the read and write speed of the hard disk. Hard drives with fast read and write speeds usually have large read and write caches.

The seek process of the hard disk is a mechanical method, which determines that its random read and write speed will be significantly lower than that of sequential read and write. When we do system design and implementation, we need to take this characteristic of hard drives into consideration.

1. Online music and video download sites
Usually music, video and other files are relatively large, so when building a website, you need to consider a relatively large hard disk as a storage condition. Therefore, when choosing a server, you should focus on choosing a server with a larger hard disk configuration and a larger bandwidth.

2. Online shopping mall websites
Online shopping malls have relatively high comprehensive performance requirements for web servers, not only in terms of server security, but also in terms of daily data processing. Therefore, when choosing a server configuration, you need to pay attention to CPU performance and website security defense issues.

The basic knowledge of server hardware configuration has been explained in detail in Xinwang above. For server hardware configuration, in addition to the familiar CPU, there are RAM, hard disk, etc. The read and write cache of the computer’s hard disk is also very important for the operation of the computer. When choosing a server configuration, you should pay attention to choosing it according to the actual use.
