Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual intervention is used for capacity expansion in heterogeneous storage environments, then flexibility and control are improved, but system complexity and management overhead increase
Solution Approach 1:
The storage system performs self-service through automated policy-driven volume expansion. The system automatically analyzes storage characteristics, creates expansion policies, and executes volume allocation without manual intervention. This eliminates the contradiction by replacing manual operations with autonomous system behavior that maintains flexibility through policy configurations while reducing management complexity.
Solution Approach 2:
The system changes parameters by dynamically adjusting volume expansion based on analyzed storage characteristics and policy parameters. Instead of fixed manual procedures, the system modifies volume allocation parameters automatically based on real-time storage conditions, resolving the contradiction between operational flexibility and management complexity.
2Productivity
If automated policy-driven solutions are implemented for volume management, then productivity and efficiency are improved, but system complexity increases
Solution Approach 1:
The volume management system is segmented into distinct functional modules: storage characteristic analysis, policy creation, and volume allocation. Each module performs a specific function independently, which improves productivity through automated workflows while managing complexity by dividing the system into manageable, specialized components.
Solution Approach 2:
Policy acts as an intermediary between storage characteristics and volume allocation decisions. The policy layer translates storage requirements into automated expansion actions, improving productivity by enabling automated decision-making while reducing the perceived complexity for users who interact only with high-level policy definitions.
3Adaptability or versatility
If meta volumes are allocated based on analyzed storage characteristics, then adaptability to different storage needs is improved, but the complexity of policy creation increases
Solution Approach 1:
Storage characteristics are analyzed in advance to pre-determine optimal volume allocation policies. By performing preliminary analysis of storage conditions and requirements, the system prepares expansion policies beforehand, which improves adaptability to different storage scenarios while reducing the complexity of real-time decision-making and policy creation.
