Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems face limitations in scalability due to fixed/static connections between processors and endpoints, preventing the addition of new processors and endpoints and hindering the ability to configure connections efficiently.
Innovation Solution
An Information Handling System (IHS) that includes a connection configuration engine to dynamically reconfigure connections between processing subsystems and endpoint subsystems using a bus exchange switch device, allowing for 'hot plug' and 'link retraining' scenarios to allocate and reallocate connection resources as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed/static connections are used between processors and endpoints, then connection stability is improved, but system scalability and configurability deteriorate
Solution Approach 1:
The patent implements dynamic connection configuration by replacing fixed hardware connections with a programmable bus exchange switch device that can reconfigure processor-endpoint mappings at runtime. The connection configuration engine dynamically updates the switch fabric to establish new connection topologies without physical reconfiguration, enabling the system to adapt to changing computational needs while maintaining stable operational connections.
Solution Approach 2:
The bus exchange switch device serves multiple functions: it acts as a connection router, a configuration manager, and a scalability enabler. The same switch fabric handles both stable operational traffic and dynamic reconfiguration requests, while the connection configuration engine manages both existing connection maintenance and new processor-endpoint pairings, reducing the need for separate dedicated components.
2Device complexity
If fixed/static connections are used between processors and endpoints, then hardware complexity is reduced, but system adaptability and reconfigurability deteriorate
Solution Approach 1:
The bus exchange switch device serves as an intermediary layer between processors and endpoints, abstracting the complexity of direct fixed connections. Instead of requiring complex custom routing logic in each processor, the switch fabric provides a standardized interface that handles connection management centrally, simplifying individual component design while enabling system-level configurability.
Solution Approach 2:
The connection configuration engine enables self-service reconfiguration by automatically managing the update of connection tables and switch fabric configuration based on runtime requirements. The system can autonomously handle processor-endpoint pairing changes without manual hardware intervention, maintaining low operational complexity while achieving high adaptability.
3Adaptability or versatility
If dynamic reconfiguration is implemented, then system scalability and adaptability are improved, but connection stability and operational reliability may deteriorate
Solution Approach 1:
The system performs preliminary validation and configuration preparation before executing connection changes. The connection configuration engine validates reconfiguration requests against system state, prepares update sequences, and ensures compatibility checks are completed before applying changes to the bus exchange switch fabric, preventing unstable configurations from being implemented.
Solution Approach 2:
The system incorporates feedback mechanisms that monitor connection stability during and after reconfiguration operations. The connection configuration engine receives status information from the bus exchange switch fabric and adjusts reconfiguration timing and sequencing based on system response, ensuring that dynamic changes maintain operational reliability through continuous verification.

AI summary
A processing subsystem/endpoint subsystem connection configuration system includes a plurality of processing subsystems and a multi-endpoint adapter device that provides a plurality of endpoint subsystems. A bus exchange switch device couples the plurality of processing subsystems to the plurality of endpoint subsystems, and a connection configuration engine is coupled to the multi-endpoint adapter device and the bus exchange switch device. The connection configuration engine receives a connection resource request that requests connection resources for a first processing subsystem that is included in the plurality of processing subsystems. Based on the connection resource request, the connection configuration engine causes at least one of the plurality of endpoint subsystems to perform a first connection resource change operation. The connection configuration engine then configures the bus exchange switch device to provide the connection resources for the first processing subsystem.
