Intelligent Block Storage Controller Mapping Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data storage technologies face inefficiencies due to the monolithic view of storage drives, leading to increased failure rates, high operational costs, and security concerns, as they treat entire drives as inoperable upon partial failures, requiring costly replacements and physical destruction of failed drives to prevent data breaches.
Innovation Solution
An intelligent data storage controller that employs many-to-one or one-to-many mapping of logical blocks to physical blocks, allowing for active management of storage drives, compression, and error correction, enabling continued operation despite partial failures and reducing the need for physical replacements, while maintaining performance and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional monolithic storage drive management is used, then simplicity of operation is maintained, but reliability deteriorates as entire drives must be replaced upon partial failures
Solution Approach 1:
The patent segments the storage drive into multiple independent functional units (read/write channels, heads, platter surfaces) that can operate independently. The controller manages these segmented units separately, allowing partial failures in one segment without affecting other segments. This enables the system to maintain operation with degraded functionality rather than complete failure.
Solution Approach 2:
The intelligent controller acts as an intermediary between the computing system and the physical storage drive components. It abstracts the complexity of managing segmented drive components while providing simplified interfaces to the computing system. The controller handles remapping, defect management, and coordination of multiple drive components, shielding the computing system from these complexities.
2Quantity of substance
If linear mapping is used, then mapping simplicity is maintained, but storage capacity utilization deteriorates due to inability to map multiple logical blocks to one physical block
Solution Approach 1:
The patent implements mapping schemes that allow multiple logical blocks to be merged and mapped to a single physical block. This enables efficient utilization of physical storage capacity by consolidating data from multiple logical blocks. The controller manages the merging and retrieval of data, maximizing the use of available physical blocks while maintaining logical block addressing.
3Ease of manufacture
If storage drives are replaced upon failure, then data security is maintained through physical destruction, but operational costs increase due to frequent replacements
Solution Approach 1:
The patent implements defect management and remapping capabilities that prepare the system in advance for potential failures. When defects are detected in drive components, the controller proactively remaps logical blocks away from affected physical blocks before complete failure occurs. This cushioning approach prevents data loss and extends drive life without requiring immediate replacement or physical destruction.
