Pluggable Data Forwarding Layout for High-Speed Cabinet Networking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data center deployment methods, such as one-by-one deployment of rack servers, fail to meet the high requirements for deployment efficiency and server density in large-scale data centers. Additionally, existing switch configurations in server cabinets result in long cables, significant signal loss, and an inability to support high-speed network interfaces.
Innovation Solution
A data forwarding device comprising an adapter and network devices that connect in a pluggable manner without cabling, reducing signal losses and space overheads. The network devices independently implement network forwarding functions, allowing for maintenance without affecting other network devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the panel interface of the switch is connected to the signal connector using a cable, then the switch can be integrated in the switch box, but the cable becomes long, causing significant signal loss and inability to support high-speed network interface
Solution Approach 1:
The patent extracts the cable connection from the switch box structure, allowing the network device to be directly connected to the signal backplane without passing through the switch box's signal connector. This eliminates the long cable path and associated signal loss while maintaining the integrated deployment benefit.
Solution Approach 2:
The patent introduces a direct connection path as an intermediary between the network device and the signal backplane, bypassing the traditional switch box connection path. This intermediary connection enables high-speed network interfaces by providing a short, direct signal path without the signal degradation caused by long cables.
2Ease of operation
If all panel interfaces of the switch are disposed on a same side for ease of operation, then maintenance and mounting are facilitated, but the cable connection path becomes longer
Solution Approach 1:
The patent removes the cable connection from the system by enabling direct connection of the network device to the signal backplane. This extraction eliminates the trade-off between interface accessibility and cable length, as the cable is no longer needed regardless of interface placement.
3Productivity
If pre-integration of server and switch is performed using entire server cabinet, then on-site deployment efficiency is improved and deployment period is shortened, but the cable-based connection causes signal loss
Solution Approach 1:
The patent extracts the problematic cable connection from the pre-integrated cabinet system by enabling direct connection of network devices to the signal backplane. This maintains the deployment efficiency benefits of pre-integration while eliminating the signal quality issues caused by long cables in the traditional switch box configuration.
