NVME Backboard Lighting via VPP Address Parsing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for lighting NVME backboards result in complex mainboard links, low resource utilization, and address differentiation issues, leading to out-of-order backboards and increased complexity.
Innovation Solution
A lighting control method and system that parses VPP signals on the mainboard to determine and deliver specific VPP addresses to NVME backboards, eliminating the need for multiple VPP interfaces and dip switches, and allowing multiple backboards to be lit with a single VPP signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple VPP interfaces are connected to light multiple NVME backboards, then multiple backboards can be lighted, but the mainboard link becomes complex and resource utilization is low
Solution Approach 1:
The patent merges multiple VPP interface functions into a single VPP interface by introducing a VPP address field in the signal. This allows one interface to address and control multiple NVME backboards through address multiplexing, thereby reducing the number of physical interfaces needed while maintaining the ability to light multiple backboards independently
Solution Approach 2:
The single VPP interface is designed to serve multiple NVME backboards simultaneously by incorporating address identification capability. The interface becomes universal, capable of communicating with any connected backboard through address-based routing, eliminating the need for dedicated interfaces for each backboard
2Quantity of substance
If multiple NVME backboards are connected via a single VPP interface, then resource utilization improves, but address differentiation becomes impossible without dip switches
Solution Approach 1:
The patent replaces the mechanical dip switch system with an electronic address field embedded in the VPP signal. Instead of physically configuring addresses through switches, the system uses software-configurable address identification in the digital signal, eliminating mechanical components and improving reliability while maintaining address differentiation capability
Solution Approach 2:
The VPP address field acts as an intermediary between the single VPP interface and multiple NVME backboards. This address identifier mediates the communication, allowing the interface to distinguish which backboard should receive the lighting signal without requiring physical address switches on each backboard
3Ease of operation
If dip switches are added to set VPP addresses for each NVME backboard, then address differentiation is achieved, but the backboard becomes out of order and complexity increases
Solution Approach 1:
The patent extracts the address differentiation function from the NVME backboard hardware and relocates it to the VPP signal structure. By moving the address identification capability to the mainboard's VPP interface, the backboards are relieved of the burden of having dip switches, thereby reducing backboard complexity and potential failure points

AI summary
There are provided a lighting control method, system, and device for an NVME backboard, and a medium. The method is applied to a mainboard. The method includes: executing a target code for parsing a target VPP signal upon reception of the target VPP signal, where the target code is added in the mainboard in advance and stores VPP addresses respectively corresponding to NVME backboards connected with the mainboard; parsing the target VPP signal to obtain a target VPP address corresponding to the target VPP signal; and delivering the target VPP address to a target NVME backboard corresponding to the target VPP address to light the target NVME backboard.
