A multi-channel server and its board card interconnection structure

Abstract

The invention discloses a board-card interconnection structure of a multichannel server. The board-card interconnection structure comprises a rigid backboard and a plurality of mainboards and further comprises an elastic backboard arranged on the surface of the rigid backboard, and each mainboard is in signal connection with the elastic backboard through a data connector to realize data transmission among the mainboards. Through signal connection between the elastic backboard and the mainboards, dielectric constant and loss angle of the elastic backboard are lower than those of the rigid backboard, so that dielectric loss is lowered to certain extent when signals are transmitted on the elastic backboard, and signal attenuation during board-card interconnection can be lowered effectively. The elastic backboard is thin in thickness, good in bending performance, quite small in occupied space, flexible in arrangement and adaptive to narrow mounting space in the server. The invention further discloses the multichannel server comprising the board-card interconnection structure. The multichannel server has the above advantages.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a board interconnection structure of a multi-channel server. The present invention also relates to a multi-channel server comprising the board interconnection structure. Background technique [0002] With the rapid development of science and technology, more and more governments, universities and other institutions have generated more types of demand for servers. [0003] A server, also called a server, is a device that provides computing services. Since the server needs to respond to and process service requests, generally speaking, the server should have the ability to undertake and guarantee services. The composition of the server includes processors, hard disks, memory, system buses, etc., which are similar to general-purpose computer architectures, but due to the need to provide highly reliable services, processing power, stability, reliability, security, scalability, scal...

Problems solved by technology

However, not all types of motherboards and backplanes can use orthogonal connections. Due to the differences in transmission signals or interfaces, some data transmission signals have to add additional extended data transmission paths on the backplane, plus motherboards and other interconnections. Due to the loss of the board itself, the data transmission signal is likely to be greatly attenuated during transmission on the backplane, resulting in failure to recover when it reaches the receiving end, and the problem of signal analysis error occurs
