Description

A chassis applied to 8U server

technical field

The invention relates to the technical field of computer hardware equipment, in particular to a chassis applied to an 8U server.

Background technique

With the development of science and technology, the replacement of servers is becoming more and more frequent, and the types of servers are emerging in an endless stream. Therefore, the server chassis is also rapidly updated with the development of servers. 8U server is a high-end server product, which has greater cost performance and advantages than general-purpose servers.

The chassis of the traditional 8U server, when installing or maintaining the modules in the chassis, is assembled and maintained from the front and rear ends of the chassis. However, since the midplane module is located in the middle of the chassis, when maintaining the midplane module, all modules on the front or rear must be removed for maintenance. On the one hand, there is great inconvenience in operation. On the other hand, since the mid-backplane module is located in the middle of the chassis and has a deep installation depth, it is easy to be bumped or scratched during installation and removal. As for the mid-backplane module, a large number of chips are placed on the mid-backplane, which plays a pivotal role in the entire server, and bumps and scratches can easily affect the normal operation of the server.
