Selective Network Merging in Fibre Channel Fabrics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The scalability, performance, and security of Fibre Channel fabrics are compromised as they grow in size, and the creation and administration of logical networks spanning multiple isolated communications networks are resource intensive, sensitive to timeouts, and inefficient.
Innovation Solution
Implementing 'enforce' and 'speed' tags in network switches to selectively merge subsets of isolated networks, allowing for efficient and secure interconnection by configuring network switches to accept specific zones and expedite device importation, reducing the need for resource-intensive comparisons and improving connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Fibre Channel fabrics grow in size to connect more devices, then network connectivity and resource sharing improve, but stability and performance deteriorate due to timeout and retry issues during discovery processes
Solution Approach 1:
The patent divides a large Fibre Channel fabric into multiple isolated fabrics, each managing its own discovery processes independently. This segmentation prevents timeout and retry issues from propagating across the entire network, thereby maintaining stability while preserving connectivity through controlled inter-fabric links.
Solution Approach 2:
The patent introduces inter-fabric links as intermediary components that connect isolated fabrics without merging them. These intermediaries enable resource sharing and connectivity between fabrics while preventing the propagation of discovery-related timeout and retry issues, thus maintaining both connectivity and stability.
2Productivity
If logical networks span multiple isolated communications networks to share resources, then resource utilization improves, but administration becomes resource intensive and scalability is compromised
Solution Approach 1:
The patent segments the network into isolated fabrics that maintain independent zoning and discovery processes. This segmentation eliminates the need for resource-intensive cross-fabric discovery and zoning administration, thereby reducing administrative complexity while preserving resource sharing capabilities through controlled inter-fabric links.
Solution Approach 2:
The patent allows each isolated fabric to maintain its own local zoning and discovery characteristics independently. This local quality approach enables resource sharing between fabrics without requiring unified administration across all fabrics, thereby reducing overall administrative burden while maintaining resource utilization.
3Adaptability or versatility
If devices are imported across isolated networks through resource-intensive comparisons, then connectivity between networks is established, but the process is slow and sensitive to timeouts
Solution Approach 1:
The patent segments device discovery and importation processes into fabric-specific operations. Devices are discovered and imported within their own isolated fabric without requiring resource-intensive comparisons across fabric boundaries. This segmentation dramatically reduces device importation time and eliminates timeout sensitivity while maintaining connectivity through inter-fabric links.
Solution Approach 2:
The patent uses inter-fabric links as intermediaries that enable device connectivity between isolated fabrics without requiring full device importation or comparison processes. This intermediary approach establishes connectivity rapidly without the timeout-sensitive comparison processes, thereby reducing device importation time while maintaining adaptability.

AI summary
Subsets of isolated communications networks are selectively merged without merging the entire isolated communications networks, and devices are imported across isolated communications networks without merging the isolated communications networks. The presently disclosed technology provides for improved scalability, performance, and security in logical networks spanning two or more physical communications networks.
