For the selection of server chassis, heat dissipation, redundancy, and reliability are three indispensable elements. An excellent server chassis must have outstanding performance in these three aspects, while the important appearance in a PC chassis is useless and impractical on the server chassis.
The first requirement for the server is to run 24 hours a year, so the requirement for system stability even exceeds performance. Heat is the number one enemy of long-term stable operation of the host, and in the narrow space of rack mounted servers, there are also high frequency CPUs, dedicated memory, and ten thousand RPM SCSI hard drives that gather these heavyweight users. In this case, the server chassis is usually equipped with multiple large-diameter turbine fans to ensure air circulation in the front and back directions of the chassis, and to timely remove heat. And professional server cases are specially equipped with redundant fans. When a fan stops running or runs at a low speed, the backup fan can immediately start to replace the faulty fan, ensuring normal cooling of the system.
And whether it's a PC or a server, power is undoubtedly the source of power. As the heart of the entire system, a professional server chassis also adopts a redundant power supply design. When one power supply fails or the input pressure is abnormal, the other power supply immediately takes over its work, ensuring the normal operation of the system.
Secondly, the material used for server chassis is also very important. The thickness of the steel plate and the quality of the materials used directly reflect the ability to shield electromagnetic interference and ensure stable system operation.
