Host Port Assignment Interface for Storage Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Storage management systems often fail to maintain system configuration data identifying which storage volume or host port is connected to which host, leading to difficulties in data path maintenance and migration between different management system generations.
Innovation Solution
A management interface that detects unassigned host ports and prompts users to assign them through a graphical user interface, updating data structures to reflect host assignments, facilitating the migration and maintenance of system configuration data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a storage management system maintains only volume to host port mapping data, then the system complexity is reduced, but the system loses the ability to track which host is connected to which host port, causing information loss
Solution Approach 1:
The system proactively detects unassigned host ports and presents a user interface to assign them to hosts before problems occur. This preliminary action ensures complete configuration data is captured, preventing information loss about host connections while maintaining manageable system complexity through structured data collection.
2Reliability
If the system proactively detects and prompts for unassigned host ports, then configuration data completeness is improved, but the ease of operation is reduced due to additional user interactions required
Solution Approach 1:
The system performs automatic detection of unassigned host ports and generates appropriate user interface prompts without requiring manual intervention. This self-service approach maintains configuration completeness while minimizing the operational burden on users, as the system identifies and presents only the necessary assignments needed.
3Adaptability or versatility
If migration from older management systems is performed without host port assignment data, then compatibility with legacy systems is maintained, but the new system cannot maintain comprehensive configuration data
Solution Approach 1:
Upon system migration or initialization, the system proactively detects unassigned host ports and presents a user interface to capture host assignment information. This preliminary data collection ensures that when migrating from legacy systems, the comprehensive configuration data is recovered and stored, preventing information loss while maintaining compatibility through the structured assignment process.

AI summary
In a storage management interface to manage host ports in a computing system having a server and one or more hosts, a user interface is provided to facilitate assigning host ports to an associated host. In one embodiment, the user interface detects unassigned host ports which have not been identified as being assigned to an associated host, and generates a graphical user interface (GUI) page indicating unassigned host ports. User selection of at least one of the unassigned host ports indicated in the GUI page is received as well as user selection of a host to assign to the selected unassigned host ports. Once the assignment is completed, data structures storing host port assignment configuration data are updated to indicate the host assigned to the selected host ports.
