Storage Access Management via Address-Interface Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage systems face challenges in efficiently managing access to storage resources, leading to performance and reliability issues due to inefficient distribution of access routes and cache coherency overhead in enterprise storage systems.
Innovation Solution
A computer-implemented method identifies a storage subsystem with multiple address units and access interfaces, determines a target interface conclusion using address-interface correlation guidelines, and optimizes access paths to reduce cache coherency overhead and improve performance by determining the appropriate access interfaces for data retrieval and storage operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple I/O interfaces are used to access storage address units, then access speed and system throughput are improved, but cache coherency overhead increases and performance penalties occur
Solution Approach 1:
The patent segments the storage access system by introducing an access management component that divides and manages access routes to different storage address units. This component maintains address-interface correlation information to determine which I/O interface should be used for accessing specific storage address units, thereby reducing cache coherency overhead while maintaining high access speed.
2Reliability
If access routes are distributed to requesting programs, then system reliability is improved, but access efficiency decreases due to routing overhead
Solution Approach 1:
The patent applies preliminary action by pre-establishing address-interface correlation information in an access management component before actual data access occurs. When a requesting program needs to access storage resources, the system quickly determines the appropriate I/O interface using pre-computed correlation data, avoiding real-time routing overhead and maintaining high access efficiency while ensuring reliable data access.
3Adaptability or versatility
If repeated write operations are performed through multiple interfaces, then storage capacity utilization is improved, but performance penalties increase due to cache coherency maintenance
Solution Approach 1:
The patent introduces an access management component as an intermediary between requesting programs and storage address units. This intermediary maintains address-interface correlation information and determines the optimal I/O interface for each access operation. By using this mediator, the system can utilize multiple I/O interfaces for repeated write operations while minimizing cache coherency overhead and avoiding performance penalties.
