I/O Adapter Feature Tag Reassignment for Path Group Load Balancing

The patent implements dynamic reconfiguration of I/O adapters by feature tag groups, allowing the system to adaptively adjust adapter assignments based on real-time utilization statistics and demand patterns. This dynamic approach enables legacy and upgraded adapters to be dynamically allocated to different path groups, improving both reliability through redundancy and productivity through optimized utilization.

The system monitors I/O adapter utilization statistics and dynamically reconfigures adapters when utilization exceeds configurable threshold values. By changing the operational parameters (feature tag group assignments) based on monitored statistics, the system resolves the contradiction between maintaining redundant functionality and optimizing adapter utilization efficiency.

The patent applies local quality by assigning specific feature tags to different I/O adapters based on their capabilities and the requirements of path groups. Upgraded adapters with enhanced features are selectively assigned to path groups that require those specific features, while legacy adapters handle path groups with standard requirements. This localized optimization improves resource allocation efficiency while maintaining system capability.

The system creates multiple feature tag groups that can be universally applied across different path groups based on feature requirements. I/O adapters can be dynamically reassigned between feature tag groups, allowing upgraded adapters to serve multiple functions across different path groups as needed, thereby improving resource allocation efficiency while maintaining enhanced system capability.

The patent implements self-service through automated monitoring and reconfiguration of I/O adapters. The system automatically monitors utilization statistics, detects when reconfiguration is needed based on configurable thresholds, and performs dynamic reassignment of adapters between feature tag groups without manual intervention. This automation maintains adapter assignment flexibility while reducing system complexity by eliminating manual configuration tasks.

The system continuously monitors I/O adapter utilization statistics and uses this feedback to automatically trigger reconfiguration when threshold values are exceeded. This closed-loop feedback mechanism provides the flexibility of manual reconfiguration through automated decision-making, improving adapter assignment flexibility while reducing system complexity by replacing manual processes with autonomous feedback-driven control.
