The selection of chassis shall be assessed from the following aspects

As a part of computer accessories, the main function of the chassis is to place and fix all computer accessories and play a supporting and protective role. In addition, the computer case plays an important role in shielding electromagnetic radiation. Although it is not a very important configuration in DIY, using a poor quality chassis is easy to short circuit the motherboard and chassis, making the computer system very unstable. The selection of chassis shall be assessed from the following aspects.

Heat dissipation

At least two or more CPUs are used for 4U or tower servers, and SCSI disk arrays are mostly used internally, which makes the internal heat generation of the server very large. Therefore, good heat dissipation is a necessary condition for an excellent server chassis. Heat dissipation performance is mainly reflected in three aspects: the first is the number and location of fans, the second is the rationality of heat dissipation channels, and the third is the material selection of chassis materials. Generally speaking, brand server chassis such as ultramicro can do this well. Large diameter fans are used to directly heat CPU, memory and disk, forming a good heat dissipation channel from front suction to rear exhaust (tower type is bottom in, top out, forward and back out), forming a good thermal circulation system and taking away a large amount of heat in the chassis in time, Ensure the stable operation of the server. The chassis shell made of high-quality aluminum alloy or steel with strong thermal conductivity can also effectively improve the heat dissipation environment.

Redundancy

4U or tower servers are generally on the backbone network, and it is inevitable to operate 24 hours a year. Therefore, the redundancy design is also worthy of attention. First, the redundancy of the cooling system. Generally, such server chassis must be equipped with special redundant fans. When individual fans stop due to failure, the redundant fans will take over immediately; The second is the redundancy of power supply. When the main power supply fails or the voltage is unstable, the redundant power supply can take over the work and continue to supply power to the system; Third, the redundancy of storage media requires that the chassis has more hot swappable hard disk bits, which can facilitate the hot maintenance of the server.

Well designed

The well-designed server chassis will provide convenient LED display lights for maintainers to timely understand the situation of the machine. Small designs such as front USB port will also greatly facilitate users. At the same time, the chassis provides the design of front redundant power supply, which makes the power maintenance more convenient.

Sufficient materials

Materials are always the most intuitive way to measure the products of large and small factories. Take the ultramicro chassis as an example. It is also a 4U or tower chassis. Ultramicro products can reach three or four times the weight of miscellaneous products. In the case of dense cables and numerous equipment in the middle of the cabinet, the material of the chassis is directly related to the host’s ability to shield electromagnetic interference of other equipment. Because the quality of the server chassis is directly related to the stability of the system, some well-known server motherboard manufacturers will also produce professional server chassis to ensure the stability of the final server products.

In short, with the above principles of purchase and quality assurance of large manufacturers, an excellent chassis power supply will become the safest and assured home for your powerful server system.
