Hard Disk Backplane Status Acquisition via Baseboard Management Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In computer systems with multiple motherboards, existing technologies fail to reliably acquire the statuses of hard disk devices when a motherboard is not operating normally, leading to potential abnormal system operation and performance issues.
Innovation Solution
A computer system design that includes a hard disk device backplane, an information management unit, and a fan control unit, where the baseboard management controller on each motherboard communicates with the backplane and fan control unit to acquire and manage the statuses of hard disk devices, even when the motherboard is not operating normally, using a middle backplane and various communication interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the motherboard is not operating normally, then the ability to acquire hard disk device statuses through the motherboard is lost, but the system still needs to monitor hard disk device statuses
Solution Approach 1:
The patent introduces a backplane as an intermediary component that can acquire hard disk device statuses independently of the motherboard's operational state. The backplane serves as a mediator between the hard disk devices and the management system, allowing status acquisition even when the motherboard is not operating normally. This resolves the contradiction by providing an alternative communication path that doesn't depend on the motherboard's operational status.
2Device complexity
If a single hard disk device backplane is shared by multiple motherboards, then device complexity is reduced, but the ability to monitor hard disk statuses when motherboards are non-operational is lost
Solution Approach 1:
The backplane acts as an intermediary that maintains the ability to acquire hard disk statuses despite being shared by multiple motherboards. It directly communicates with hard disk devices to obtain status information, which can then be provided to management systems even when specific motherboards are non-operational. This preserves information flow while maintaining structural simplicity.
Solution Approach 2:
The backplane is designed with multi-functionality, serving both as a structural platform for multiple motherboards and as an independent status acquisition channel. It can acquire and transmit hard disk status information to multiple potential recipients (different management systems or motherboards) without requiring dedicated communication paths for each, thus maintaining simplicity while preventing information loss.
3Use of energy by moving object
If the operating system must be loaded on the motherboard to acquire hard disk statuses, then system resource usage is optimized, but timely monitoring during startup or dormancy is prevented
Solution Approach 1:
The backplane can acquire hard disk device statuses before the operating system is loaded on the motherboard. This preliminary action allows the system to have status information available during startup phases or when the system is in a dormant state, enabling timely monitoring and response without requiring the full operating system to be operational first.

AI summary
A computer system includes multiple hard disk devices, a hard disk device backplane, an information management unit, a middle backplane and multiple motherboards. The hard disk device backplane is coupled to and configured to manage the hard disk devices. The information management unit, coupled to the hard disk device backplane, is configured to acquire statuses of the hard disk devices. The middle backplane is coupled to the hard disk device backplane. The motherboards, coupled to the information management unit and the middle backplane, respectively have a baseboard management controller. When the operating system is loaded for operation on the motherboards, the baseboard management controllers are coupled to the hard disk device backplane via the middle backplane to acquire the statuses of the hard disk devices. When the motherboards are not operated normally, the baseboard management controllers acquire the statuses of the hard disk devices via the information management unit.
