Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional data replication methods are inefficient, error-prone, and slow, especially in distributed environments, due to changing factors such as bandwidth and storage characteristics, which can lead to performance degradation and require labor-intensive and error-prone physical shipping of data for disaster recovery.
Innovation Solution
A data replication management system that includes a replication management server analyzing periodic replication characteristics using reactive and predictive models to detect and predict performance degradation, employing machine learning algorithms and notifications to administrators for timely corrective measures, such as reconfiguring storage pairings, to maintain efficient data replication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data replication is performed using traditional backup applications and physical shipping, then data copies can be created at offsite locations, but the process is labor-intensive, error-prone, and extremely slow
Solution Approach 1:
The patent replaces the mechanical system of physical tape shipping with an electronic data transmission system over computer networks. The replication apparatus uses network protocols to transfer data electronically between storage devices, eliminating the need for physical media handling and shipping while dramatically increasing replication speed and reducing errors.
Solution Approach 2:
The patent creates digital copies of data that can be transmitted electronically across networks. Instead of copying data to physical tapes that must be manually handled and shipped, the system creates digital replicas that can be transmitted instantly over network infrastructure, improving both speed and reliability.
2Adaptability or versatility
If data replication factors such as bandwidth availability and storage characteristics change over time, then system adaptability is required, but traditional static replication methods cannot adjust to these changes
Solution Approach 1:
The patent implements dynamic replication by continuously monitoring system conditions such as bandwidth availability, storage characteristics, and data changes. The replication apparatus automatically adjusts replication parameters and timing based on real-time conditions, transforming a static system into one that adapts dynamically to changing environments without requiring manual intervention.
Solution Approach 2:
The patent incorporates feedback mechanisms where the replication system monitors its own performance and system conditions, then uses this information to adjust future replication operations. The apparatus tracks replication status, detects changes in bandwidth or storage characteristics, and modifies replication behavior accordingly, creating a self-regulating adaptive system.
3Reliability
If automated detection of replication performance degradation is implemented, then proactive measures can be taken, but this requires analyzing periodic replication characteristics using complex models
Solution Approach 1:
The patent applies predictive modeling to analyze replication characteristics and predict potential performance degradation before it occurs. By examining trends in replication data, bandwidth usage, and system conditions, the system performs preliminary assessments that enable proactive intervention, preventing degradation rather than merely reacting to it.
Solution Approach 2:
The patent introduces an intermediary analysis layer that sits between the replication process and the control system. This intermediary component collects and analyzes replication characteristics, using modeling techniques to interpret data and generate predictions, thereby simplifying the overall system architecture while enabling sophisticated performance monitoring.
Data Source
AI summary
Techniques for automatically detecting data replication performance degradation are described. According to one embodiment, a method starts with receiving periodically data replication characteristics from a source storage and a target storage, the data replication characteristics being extracted from a replication process of the source storage replicating data to the target storage. The received data replication characteristics are analyzed at a replication management server communicatively coupled with the source storage, and the target storage and data replication performance degradation is detected based on analyzing the received data replication characteristics and applying one or more rules of data replication performance degradation. When the one or more applied rules indicating that a data replication performance degradation has been detected, a notification is sent out.
