Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current backup power systems for computing data storage systems face inefficiencies in communicating and managing backup power distribution among multiple loads, particularly during primary power supply removal, leading to increased configuration time and error handling challenges.
Innovation Solution
A system utilizing a pass-through device supporting a multi-master communication protocol allows the shared backup power supply to directly communicate with loads, enabling efficient error handling and reduced configuration time by acting as a master component, along with the BMC unit, to manage and provide backup power effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional backup power communication system is used, then the system can provide backup power to loads, but the configuration time is increased and error handling becomes complex
Solution Approach 1:
The patent introduces a backup power controller as an intermediary device that manages communication between the backup power supply and multiple loads. This controller implements a multi-master communication protocol that allows direct communication between the backup power supply and loads, eliminating the need for complex hierarchical communication structures and reducing configuration time while maintaining reliable backup power delivery.
Solution Approach 2:
The backup power controller is designed with multi-functional capabilities, serving as both a communication manager and a power distribution controller. It supports multiple master devices in the communication network and can dynamically allocate backup power to different loads based on their needs, thereby reducing configuration complexity and time while ensuring reliable power delivery.
2Reliability
If a traditional backup power communication system is used, then the system can manage power distribution, but error handling complexity increases
Solution Approach 1:
The backup power controller acts as an intermediary that simplifies error handling by centralizing communication management. It implements error detection and correction mechanisms at the controller level, reducing the complexity of error handling across the entire system while maintaining reliable power distribution to multiple loads.
Solution Approach 2:
The system implements feedback mechanisms where the backup power controller continuously monitors the status of the backup power supply and loads. This real-time feedback enables automatic error detection and response, reducing the complexity of manual error handling while ensuring reliable power distribution.
3Loss of time
If direct communication between backup power supply and loads is implemented, then configuration time is reduced, but communication protocol complexity increases
Solution Approach 1:
The backup power controller implements a multi-master communication protocol that enables direct communication between the backup power supply and multiple loads. This protocol is designed to be universally compatible with different load types while maintaining simplified configuration procedures, thus reducing configuration time without proportionally increasing protocol complexity.

AI summary
Example implementations relate to backup power communication. For example, a system for backup power communication can include a shared backup power supply coupled to a node, a plurality of loads supported by the node, and a pass-through device to support multi-master communication between the shared backup power supply and the plurality of loads.
