Proxy Controller Registration of Non-Compliant Storage Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage network systems face challenges in automatically managing non-compliant network devices, requiring significant manual effort and time to integrate them into the network.
Innovation Solution
A proxy controller is introduced to automatically discover and configure non-compliant storage devices by querying the central controller for registered devices, performing a scan to identify non-compliant devices, collecting configuration information, and registering itself as a single device that includes these non-compliant devices as subsystems, allowing the central controller to manage them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual integration methods are used for non-compliant devices, then integration can be completed, but significant manual effort and time are required
Solution Approach 1:
A proxy controller is introduced as an intermediary component between the central controller and non-compliant storage devices. The proxy controller translates and adapts communication protocols, enabling automatic integration of non-compliant devices without requiring manual configuration. This mediator resolves the contradiction by automating the integration process while maintaining compatibility with existing compliant devices in the storage network.
2Adaptability or versatility
If the central controller directly manages all devices, then management is simplified, but non-compliant devices cannot be automatically discovered or configured
Solution Approach 1:
The controller functionality is segmented into two distinct components: a central controller that manages compliant devices and a proxy controller that handles non-compliant devices. This segmentation allows the central controller to maintain its simplified management approach for compliant devices while the proxy controller provides specialized adaptation capabilities for non-compliant devices, enabling both automatic management and broad device compatibility.
Solution Approach 2:
The proxy controller serves as an intermediary layer that bridges the gap between the central controller's standardized management interface and the diverse, non-compliant device interfaces. It performs protocol translation and adaptation, allowing the central controller to automatically manage non-compliant devices without direct interaction, thus achieving both versatility and automation.
3Adaptability or versatility
If non-compliant devices are integrated into the storage network, then device versatility is improved, but the complexity of the management system increases
Solution Approach 1:
The proxy controller acts as a mediator that handles all protocol translation and adaptation complexities, shielding the central controller from dealing with non-compliant device variations. This concentrates the complexity in a single manageable component rather than distributing it throughout the entire management system, allowing non-compliant devices to be integrated without proportionally increasing overall system complexity.
Solution Approach 2:
The proxy controller combines multiple functions including protocol translation, device discovery, configuration management, and compliance adaptation into a single integrated component. This merging of functions reduces the overall system complexity by consolidating the management of diverse non-compliant devices through one unified interface rather than requiring separate management mechanisms for each device type.

AI summary
Example implementations relate to storage networks. In some examples, a proxy controller may identify all devices included in the storage network, and may identify a first subset of the storage devices that were previously registered with a central controller of the storage network. The proxy controller may also determine a second subset of the storage devices that were not previously registered with the central controller, and may register the second subset of the storage devices on the central controller of the storage network.
