Description

A server chassis fixing structure

technical field

The invention belongs to the technical field of servers, and in particular relates to a fixing structure of a server case.

Background technique

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. According to the services provided by the server, generally speaking, the server has the ability to respond to service requests, undertake services, and guarantee services.
