Workload-Aware Storage Replication Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage replication methods fail to differentiate between critical and non-critical workloads in enterprise data centers, leading to inadequate prioritization of replication processes.
Innovation Solution
A method and system that detect trigger events to populate a replication queue with workload identifiers, adjust the replication order based on workload criticality classes, and replicate active workload data from a primary to a secondary cluster infrastructure, ensuring preferential transport of critical data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If storage replication treats all workloads equally without differentiation, then the replication process is simple to implement, but critical workload data does not receive prioritized replication
Solution Approach 1:
The patent applies local quality by assigning different replication priorities to different workloads based on their criticality levels. Critical workloads receive high-priority replication while non-critical workloads receive standard replication, allowing the system to treat different parts of the data differently according to their specific needs rather than applying a uniform replication approach to all data
2Reliability
If storage replication prioritizes critical workload data, then data availability for critical applications is improved, but the replication process becomes more complex
Solution Approach 1:
The patent implements preliminary action by pre-classifying workloads into criticality levels and pre-establishing replication priorities before replication events occur. This allows the system to have replication policies ready in advance, so when replication is triggered, the prioritization logic is already determined and does not add complexity to the actual replication execution
3Loss of time
If storage replication processes all workloads simultaneously, then replication is straightforward to manage, but critical data may experience delays due to non-critical workload traffic
Solution Approach 1:
The patent applies continuity of useful action by ensuring that critical workload replication continues uninterrupted with higher priority allocation. When replication resources are available, critical data replication proceeds continuously without being blocked or delayed by non-critical workload replication tasks, maintaining constant progress on time-sensitive data protection
4Productivity
If storage replication uses workload criticality classification, then replication prioritization is improved, but the system requires additional mechanisms to detect and classify workloads
Solution Approach 1:
The patent implements self-service by enabling workloads to self-identify their criticality level through metadata tags or labels that are automatically attached to the data. This eliminates the need for complex external classification mechanisms, as the workloads themselves provide the information needed for prioritization through their own metadata structures
Data Source
AI summary
A method and system for workload aware storage replication. Specifically, the disclosed method and system entail establishing preferential transports for critical workload data targeted for replication from one cluster infrastructure to another. Existing replication solutions fail to prioritize the replication of critical over non-critical workload data, which the disclosed method and system rectify.
