Solution Overview

Problem

Smaller scale storage area network (SAN) implementations face high costs and vendor lock-in due to proprietary management tools and limited access to advanced performance monitoring and management capabilities, which are not available in larger scale implementations.

Innovation Solution

A virtualized fabric login server is implemented, running on standard commodity hardware and open source network operating systems, providing software-defined storage area network management and monitoring capabilities, allowing it to reside on channel cards or in docker containers within the SAN, thus avoiding vendor lock-in and proprietary tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If proprietary management tools and vendor-specific implementations are used in smaller scale SANs, then basic management functionality is provided, but costs increase and vendor lock-in occurs with limited access to advanced capabilities

Engineering Contradiction:
Improveaccess to management capabilitiesVSAvoidproprietary tool requirements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fabric login server is virtualized to provide universal management capabilities across different SAN scales. By implementing the server as a virtual machine that can run on standard hardware with open-source operating systems, the solution enables smaller SANs to access advanced management and monitoring capabilities that were previously only available in larger implementations, eliminating vendor-specific tool requirements

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention copies the advanced management capabilities from large-scale SAN implementations and deploys them as virtualized fabric login servers in smaller scale environments. This allows smaller SANs to replicate the functionality of enterprise-grade management tools without requiring proprietary hardware or software, achieving the same capabilities through virtualization on commodity hardware

Inventive Principle:
Principle #26Copying

2Ease of manufacture

If virtualized fabric login server is implemented on standard commodity hardware, then costs are reduced and flexibility is enhanced, but system reliability must be maintained

Engineering Contradiction:
Improvedeployment costVSAvoidsystem stability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The invention replaces expensive, proprietary hardware with standard commodity hardware that can be easily replaced or upgraded. By running the fabric login server on virtual machines with open-source operating systems on commodity hardware, the solution reduces deployment costs while maintaining the ability to achieve desired functionality through software rather than expensive hardware dependencies

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The virtualized fabric login server provides self-service capabilities through automated management and monitoring functions. The system can autonomously perform fabric management tasks, login authentication, and performance monitoring without requiring manual intervention or proprietary tool support, thereby maintaining reliability through automated operations on commodity hardware

Inventive Principle:
Principle #25Self-service
