Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage systems face challenges in efficiently balancing the load on master containers and ports in Software Defined Network Attached Storage (SDNAS) configurations, leading to uneven workload distribution and reduced performance.
Innovation Solution
Implementing a load manager that executes containerized NAS facilities within master containers, allowing for user-initiated load-balancing actions such as relocating NAS facilities between containers and adjusting port assignments to achieve balanced load distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If NAS facilities are executed inside master containers in a distributed storage system, then system flexibility and resource utilization are improved, but load imbalance between master containers and ports occurs leading to reduced performance
Solution Approach 1:
The patent implements dynamic load balancing by continuously monitoring workload metrics (CPU utilization, memory usage, I/O operations, network traffic) of master containers and ports, and automatically relocating NAS facilities from overloaded containers to underloaded ones. This dynamic adjustment resolves the contradiction by maintaining system flexibility through containerization while preventing performance degradation through real-time load distribution optimization.
Solution Approach 2:
The load balancing mechanism incorporates feedback loops that monitor system performance metrics and use this information to make intelligent relocation decisions. The system collects data on container and port workloads, analyzes this feedback information, and automatically adjusts NAS facility placement to optimize load distribution, thereby maintaining both flexibility and performance.
2Productivity
If manual load balancing actions are implemented by relocating NAS facilities between containers, then load distribution is improved, but system complexity and operational overhead increase
Solution Approach 1:
The load balancing system operates autonomously by automatically monitoring workload metrics, making relocation decisions, and executing NAS facility migrations without requiring manual intervention. The system serves itself by managing its own load distribution, which improves load balancing effectiveness while avoiding the operational overhead and complexity associated with manual management.
Solution Approach 2:
The system performs preliminary monitoring and analysis of workload conditions before initiating any relocation actions. By continuously gathering performance data and pre-assessing load balance status, the system prepares relocation decisions in advance, ensuring smooth transitions while minimizing disruption to system operations and reducing operational complexity.
3Productivity
If port assignments are dynamically changed to balance load, then resource utilization is improved, but system stability and configuration consistency may be affected
Solution Approach 1:
The load balancing mechanism acts as an intermediary layer between NAS facilities and physical ports, managing port assignments dynamically while abstracting the complexity from the core storage operations. This intermediary layer handles port reconfiguration smoothly, ensuring that changes in port assignments do not disrupt the stability or consistency of the overall system configuration, thereby improving resource utilization without compromising system stability.
