Switch system and construction method thereof

Abstract

The invention provides a construction method of a switch system and the switch system. The construction method of the switch system comprises the following steps: providing a plurality of switch mainboards, wherein each switch mainboard includes a plurality of switch chips; connecting the plurality of switch chips on each switch mainboard as a-dimensional connection; and setting the plurality of switch mainboards on a backboard, performing b-dimensional connection and c-dimensional connection on the plurality of switch chips on the plurality of switch mainboards through the backboard to form asilicon element switch of an a x b x c mode, wherein a is greater than or equal to 2, b is greater than or equal to 2 and c is greater than or equal to 2. A 3D torus topology structure is adopted inthe silicon element switch of the switch system, and the interconnection of three dimensions is realized through a PCB (Printed Circuit Board). The technology saves the cost of optical fibers and copper cables, has a short transmission distance, and has better reliability than the optical fibers and the copper cables.

Description

technical field [0001] The present invention generally relates to the field of computer technology, more specifically, a switch and its construction method. Background technique [0002] In the specific application process of HPC (High Performance Computing, that is, high-performance computer cluster), in the process of cluster construction, parallel computing, and collaborative simulation, its performance has strict requirements on the bandwidth, delay, and topology of the system. In particular, the computing power of HPC ranges from P-level to E-level, and the number of supercomputing cores ranges from hundreds of thousands to millions, which poses severe challenges to the scale, scalability, cost, energy consumption, and reliability of the network switching system. . Therefore, in the process of building a super-large computing system, designing a large-scale network switching system that takes multi-dimensional factors such as topology, heat dissipation, and density int...

AI Technical Summary

Problems solved by technology

The fat-tree topology has disadvantages such as insufficient scalability, poor fault tolerance of routing protocols, high overhead and high cost, and limited network scale.

This type of switch is limited by port heat dissipation and system air duct design, and cannot give a good balance between density and heat dissipation

Therefore, the existing switches have various shortcomings and deficiencies, none of which can meet the requirements of E-level computing for network switching systems
