Virtual Block Addressing Map for Distributed Storage Scaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional enterprise data storage solutions require substantial and expensive dedicated resources for tracking and mapping data locations, leading to increased complexity and disruption, and often fail to scale dynamically with demand.
Innovation Solution
A computing resource provider offers scalable computing resources through services like Web services, utilizing a data mapping engine with a logical block addressing map, a placement engine, and a map authority to manage data access and storage across multiple nodes, ensuring data integrity and availability by replicating data and optimizing storage configurations based on demand and system performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated resources are invested for tracking and mapping data locations in conventional storage solutions, then data management reliability is improved, but device complexity and cost increase
Solution Approach 1:
The patent uses a virtual block addressing map that copies and abstracts the physical storage location information, allowing the system to track data locations without requiring complex dedicated hardware resources. The virtualization layer creates a simplified representation of storage locations that can be managed through software rather than expensive dedicated infrastructure.
Solution Approach 2:
The patent introduces a virtualization layer as an intermediary between the storage system and the data management layer. This virtual block addressing map acts as a mediator that translates complex physical storage locations into simplified virtual addresses, reducing the need for direct complex tracking mechanisms while maintaining reliable data management.
2Measurement precision
If additional computing resources are added for tracking data locations, then data mapping capability is improved, but loss of time and productivity increase
Solution Approach 1:
The system performs self-service by automatically managing the virtual block addressing map and data location tracking without requiring manual intervention or additional dedicated computing resources. The virtualization layer automatically handles mapping operations, reducing time loss and improving productivity while maintaining precise data mapping capabilities.
3Quantity of substance
If conventional storage solutions are implemented, then data storage capability is provided, but adaptability to demand changes is reduced
Solution Approach 1:
The patent implements a dynamic virtual block addressing map that can automatically adapt to changing storage demands. The virtualization layer enables flexible allocation and reallocation of storage resources based on actual needs, allowing the system to scale and adjust without being constrained by fixed physical infrastructure, thereby improving adaptability while maintaining data storage capability.
Data Source
AI summary
A storage controller is implemented for controlling a storage system. The storage controller may be implemented using a distributed computer system and may include components for servicing client data requests based on the characteristics of the distributed computer system, the client, or the data requests. The storage controller is scalable independently of the storage system it controls. All components of the storage controller, as well as the client, may be virtual or hardware-based instances of a distributed computer system.
