Tiered Storage Throughput via Multi-Interface Drive Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mass storage systems face challenges in scalability and upgradeability as they require identical or equivalent storage drives for replacement, which can become obsolete with advancing storage technologies, limiting the ability to maintain or upgrade the system effectively.
Innovation Solution
The implementation of tiered storage assemblies with sub-units having different maximum drive interface throughputs allows for the replacement of failed storage drives with faster throughput drives that can operate across multiple interfaces, enabling efficient upgrading and maintenance without altering the overall system throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If identical storage drives are required for replacement, then system reliability is maintained, but adaptability to storage technology advancements is limited
Solution Approach 1:
The patent applies local quality by creating different drive interfaces with varying throughput capabilities within the same mass storage assembly. Some interfaces are configured for lower throughput while others are configured for higher throughput, allowing storage drives to be selectively replaced based on their specific interface requirements. This enables the system to accommodate both legacy and advanced storage drives in the same assembly, resolving the contradiction between maintaining reliability through standardized replacements and adapting to technology advancements.
2Duration of action of stationary object
If storage drives are replaced while operational, then system continuity is maintained, but complexity of replacement operations increases
Solution Approach 1:
The patent segments the mass storage assembly into multiple independent drive interfaces, each with its own throughput characteristics. This segmentation allows individual storage drives to be replaced at different interfaces without affecting the entire system. The controller can manage replacements at specific interfaces while other interfaces continue to operate, thereby maintaining system continuity while simplifying the replacement process through independent interface management.
3Speed
If higher throughput drives are used, then data transfer performance is improved, but compatibility with existing drive interfaces is reduced
Solution Approach 1:
The patent implements universality by designing drive interfaces that can support multiple throughput levels. Each interface is configured to work with storage drives of varying speeds, allowing high-throughput drives to operate at lower speeds when connected to slower interfaces, and vice versa. This multi-functional interface design enables high-performance drives to be used across the system while maintaining compatibility with existing interfaces, thus improving data transfer performance without sacrificing compatibility.
