Solution Overview

Problem

Conventional methods for modifying host-to-volume mappings in storage systems require manual creation and management of numerous script files, making it challenging and difficult to automate and manage large numbers of configurations efficiently.

Innovation Solution

The solution involves representing host-to-volume mappings as mapping configuration components, where only one configuration is active at a time, allowing for easy activation and deactivation of different configurations to manage changes, such as repartitioning, repurposing, or disaster recovery, through a management component within the storage system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual script files are used to modify mapping configurations, then flexibility in customization is improved, but device complexity and ease of operation deteriorate due to the need to create and manage numerous script files

Engineering Contradiction:
Improveconfiguration flexibilityVSAvoidscript file management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the mapping configuration management into discrete, independently manageable mapping configuration components. Each component represents a specific host-to-volume mapping configuration and can be individually activated or deactivated. This segmentation eliminates the need to manage numerous interconnected script files while maintaining configuration flexibility, as each component can be modified, activated, or deactivated independently through the management interface.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If numerous script files are created to represent different mapping configurations, then adaptability is improved, but ease of operation and productivity worsen due to the challenge of managing and testing large numbers of script files

Engineering Contradiction:
Improvemapping configuration varietyVSAvoidscript file management ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent merges the functionality of multiple separate script files into a unified management framework where all mapping configurations are represented as components within a single storage system. The management interface provides centralized control to activate or deactivate specific mapping configuration components, eliminating the need to manually create, test, and manage numerous separate script files while preserving the ability to implement multiple different mapping configurations.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If mapping configurations are modified through manual script creation, then customization capability is improved, but productivity and time efficiency deteriorate due to the extensive effort required to create and manage script files

Engineering Contradiction:
Improveconfiguration customizationVSAvoidconfiguration modification speed
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent implements preliminary action by pre-defining mapping configuration components within the storage system that can be directly activated or deactivated. Instead of requiring manual script creation at the time of configuration change, the system allows administrators to prepare and store multiple mapping configuration components in advance, then rapidly switch between them by simply activating or deactivating components through the management interface, dramatically improving configuration modification speed while maintaining full customization capability.

Inventive Principle:
Principle #10Preliminary action

AI summary

The present invention is directed to a method and software for managing the host-to-volume mappings of a SAN storage system. The host-to-volume mappings of the SAN storage system are represented in mapping configuration components. The active mapping configuration component represents the current host-to-volume mapping for the SAN storage system. Only one mapping configuration component is active at a time. The host-to-volume mappings of the SAN storage system are changed by deactivating the active mapping configuration component and activating an inactive mapping configuration component that represents a different mapping configuration, effecting a repartition, repurpose, disaster recovery, or other business activity. This can be a scheduled task or performed in an on-demand manner. The mapping configuration components are managed and controlled through the management component of the SAN storage system.
