What is the difference between the server host and PC? To solve this problem, today the editor summarizes this article about server host and PC, hoping to help more friends who want to solve this problem to find a more simple and easy way.

First of all, the server is also divided into rack servers and tower servers, most of the size of rack servers is very exaggerated, obviously not suitable for use at home, because 24-hour uninterrupted operation, the server is designed to ensure stable heat dissipation, and can also put down enough server motherboard CPU memory package, of course, we will not talk about this in detail, mainly to talk about the differences between components.

The first thing to talk about is CPU. At present, the server CPU is still dominated by Intel (EPYC is rising, maybe it will be evenly divided in a few years). This kind of server CPU is characterized by many cores, many threads, large cache and low frequency. 90% of our daily use of home computers will not use more than 8 cores, of course, if you often use professional graphics software such as rhinoceros, C4D, etc. If you play games, you also like the low core and high main frequency, and the server has to deal with a lot of small data, so the advantage of multi-threading is very obvious.

At the same time, because of the uninterrupted work of 24-7, the stability of the server CPU is very exaggerated, and its physique is much better than that of the household CPU. The CPU used on the ordinary PC often uses an one-digit size of one, two, three buffers, but the cache on the server CPU is often as high as ten megabytes, which also makes the CPU have stronger data processing capacity and faster data output. Of course, the instruction set of the server CPU is also more centralized and targeted, because of the use of RISC, the server CPU is faster to call for a specific purpose, and the hit rate is higher. After talking about the CPU, let's talk about the difference between the motherboard. Of course, we have to bring the CPU here, because the motherboards of many servers will support the installation of multiple CPU for stronger performance, that is, we often hear about several servers, which is completely different from the household PC that can only install one CPU.

The second is better workmanship, after all, endless work, and multi-channel CPU power consumption is also very exaggerated, so the motherboard power supply requirements are very high, while cooling will be better, of course, the problem is larger; in addition, the server motherboard for better performance will also support ECC memory, SCSI hard drives and multiple motherboard processing clusters, the purpose is one: stronger and more stable.

After talking about the motherboard, we talk about memory, currently servers generally use ECC memory, the biggest feature of this memory is to support automatic error correction, because the reduction of data error problems, so the server stability will be better (of course, AMD family new products support ECC memory, which compared to Intel's advantage is very big), as to whether the speed is fast, to be honest, some are not as fast as ordinary SDRAM, focusing on stability.

Finally, let's talk about hard drives and power supplies. Hard drives used on servers often use special ultra-high-speed hard drives, such as Seagate's ST10000NM0016 Galaxy and Seagate 300G / 15000R/SAS hard drives, which support SAS, RAID and SMART functions, while high speed can also provide better read and write speed, but more and more solid state drives are joining the server. The server supports hot-swappable hard disk, but also has more hard disk slots and interfaces, which makes the server more resistant to data impact and more stable in special cases.

In terms of power supply, servers often choose ultra-high power and high stability power supply. The conversion rate, noise control and other issues that PC pays attention to are not very important in server power supply. The most important thing is to provide sufficient power and outstanding stability, so the noise of server power is often exaggerated (anyway, there is a server room, in addition to server management and operation and maintenance, who will squat in the server room every day). Finally, I would also like to add that the server host does not need a graphics card, because in most cases, the server does not need to output complex graphics, and even targeted servers do not need a graphical interface at all, even ordinary servers, it is generally not connected to the monitor when running, and the video card is a pure encumbrance.

These are the details of the gap between the server host and PC. Is there anything to gain after reading it? If you want to know more about it, you are welcome to follow the industry information!
