Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing partitioned computing systems fail to effectively detect and respond to faults that impact multiple partitions, leading to potential system performance degradation.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If partitioning is employed to enhance reliability and system efficiency, then system reliability and efficiency are improved, but fault detection and response capability across partitions deteriorates
Solution Approach 1:
The patent introduces a management controller as an intermediary component that monitors faults across multiple partitions. The management controller receives fault indications from different partitions, determines whether they constitute a system-wide fault condition, and coordinates the shutdown response. This intermediary enables centralized fault detection and response without requiring complex inter-partition communication mechanisms.
Solution Approach 2:
The system implements feedback mechanisms where each partition reports its operational status and fault conditions to the management controller. The management controller continuously receives this feedback, analyzes the collective state of all partitions, and triggers appropriate responses based on the determined fault condition. This feedback loop enables dynamic monitoring and response to changing system states.
2Productivity
If partitions operate independently to serve specific functions, then system efficiency and security are improved, but coordinated fault response across partitions deteriorates
Solution Approach 1:
The management controller serves as a mediator that simplifies fault response coordination while maintaining partition independence. Instead of requiring complex peer-to-peer communication between partitions for coordinated fault response, the management controller centralizes this function. It receives fault indications from independent partitions, determines system-wide fault conditions, and coordinates the shutdown response, thereby reducing the complexity of inter-partition coordination.
Solution Approach 2:
The system segments fault detection and response functions: individual partitions handle local fault detection and reporting, while the management controller handles system-wide fault condition determination and coordinated response. This segmentation allows partitions to operate independently for their specific functions while still enabling coordinated fault response through the management controller's oversight.
3Reliability
If fault monitoring is implemented across all partitions, then system reliability is improved, but system complexity and resource consumption increase
Solution Approach 1:
The management controller acts as an intermediary that consolidates fault monitoring functions. Instead of requiring each partition to implement its own comprehensive monitoring and analysis capabilities, the management controller receives fault indications from all partitions and performs the system-wide fault condition determination. This centralization reduces the complexity burden on individual partitions while maintaining comprehensive monitoring capability.
Solution Approach 2:
The patent extracts the complex fault analysis and coordination functions from the individual partitions and places them in the management controller. Each partition only needs to implement simple fault detection and reporting, while the management controller handles the complex tasks of determining system-wide fault conditions and coordinating responses. This extraction reduces the complexity of the monitoring system overall.

AI summary
A method is disclosed for alerting a co-tenant of a fault in a partitioned system. An apparatus and system also perform the functions of the method. The method includes monitoring, for faults, two or more partitions in a system sharing a management controller where each of the partitions is associated with a tenant. The method includes detecting a fault on a first partition and identifying an alert class of multiple alert classes for the fault. The method includes identifying the alert class of the fault as a high-level alert class indicating that the fault affects one or more other partitions different than the first partition. The method includes notifying the tenant of the first partition and each tenant of the one or more other partitions of the fault in response to the alert class being the high-level alert class.
