Storage Array I/O Pattern Monitoring for Application-Consistent Snapshots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for generating application-consistent snapshots require an application-aware agent on the host, limiting efficiency and flexibility in snapshot generation.
Innovation Solution
A computer-implemented method that monitors I/O operations and identifies pre-defined patterns to generate application-consistent or crash-consistent snapshots without installing agents on hosts, using real-time analytics to determine snapshot generation within a defined application-consistency time limit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If application-aware agents are deployed on hosts to generate application-consistent snapshots, then snapshot consistency is improved, but system complexity and deployment difficulty increase
Solution Approach 1:
The patent extracts the agent functionality from the host system and relocates it to the storage array. The storage array independently monitors I/O operations and identifies application-consistent snapshot points without requiring external agents on hosts, thereby reducing system complexity while maintaining snapshot consistency
Solution Approach 2:
The storage array performs self-monitoring of I/O operations and self-determination of snapshot consistency points. The system uses embedded logic to automatically detect application-specific I/O patterns and generate snapshots without external orchestration, enabling the system to serve its own consistency requirements
2Reliability
If application-aware agents are deployed on hosts to generate application-consistent snapshots, then snapshot consistency is improved, but deployment flexibility and efficiency decrease
Solution Approach 1:
By extracting the agent from the host and embedding it in the storage array, the patent eliminates deployment constraints related to host accessibility and agent installation. The storage array can autonomously perform monitoring and snapshot generation, providing greater deployment flexibility across diverse host environments
Solution Approach 2:
The storage array is designed with universal functionality to handle multiple types of I/O operations and identify various application-consistent patterns. This multi-functional capability allows the system to adapt to different workloads and applications without requiring specialized agents for each scenario
3Productivity
If I/O operations are monitored to identify pre-defined patterns for snapshot generation, then snapshot generation efficiency is improved, but processing time and computational resources increase
Solution Approach 1:
The patent implements preliminary action by pre-defining I/O patterns that indicate application-consistent snapshot points. The storage array monitors for these predetermined patterns rather than performing complex real-time analysis, enabling efficient identification of snapshot opportunities without excessive processing overhead
Solution Approach 2:
The system uses heuristics to skip unnecessary monitoring and analysis steps. By focusing only on pre-defined I/O patterns and using rule-based detection, the system rapidly identifies snapshot points without getting bogged down in comprehensive I/O operation analysis, thereby reducing processing time
