Solution Overview

Problem

Existing home storage systems fail to effectively leverage hybrid RAID functionality for improving speed, storage size, and functionality, despite advancements in GUI architecture, tiered management, and power-efficient data storage solutions.

Innovation Solution

A PCI-Express-based hybrid RAID controller system that integrates semiconductor storage devices (SSD) and hard disk drive (HDD/Flash) memory units, coupled with a main controller, display controller, external memory controller, and external interface, enabling network connectivity and high-speed data processing through synchronization adjustments in data signals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If hybrid RAID functionality is integrated with both SSD and HDD/Flash memory units, then storage speed and functionality are improved, but device complexity increases

Engineering Contradiction:
Improvedata processing speedVSAvoidcontroller system complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The storage system is segmented into different memory tiers (SSD and HDD/Flash) with distinct performance characteristics. The hybrid RAID controller manages these segments separately, allowing each to operate optimally while providing unified access through the RAID subsystem. This segmentation resolves the contradiction by enabling high-speed access to frequently used data on SSDs while maintaining system manageability through structured organization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hybrid RAID controller is designed as a multi-functional device that simultaneously manages both SSD and HDD/Flash memory units, providing RAID functionality across different storage technologies. This universal controller consolidates what would otherwise be separate control systems, improving speed through hybrid storage while avoiding proportional increases in overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If tiered storage management is implemented with different access speeds, then storage functionality and speed are improved, but ease of operation deteriorates

Engineering Contradiction:
Improvestorage functionalityVSAvoidsystem management ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The storage system implements self-service through automated data tiering and hot-swapping capabilities. The hybrid RAID controller automatically manages data distribution between SSD and HDD/Flash tiers based on access patterns, and enables hot-swapping of storage units without requiring manual intervention. This maintains high adaptability while significantly improving ease of operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system dynamically changes storage parameters such as access speed, capacity, and redundancy based on workload requirements. The hybrid RAID controller adjusts data placement and access methods automatically, allowing the system to adapt to varying operational needs without requiring users to manually reconfigure storage parameters, thus maintaining ease of operation.

Inventive Principle:
Principle #35Parameter changes

3Loss of energy

If low power disk drives are used for caching, then power consumption and access times are reduced, but storage capacity is limited

Engineering Contradiction:
Improvepower consumptionVSAvoidstorage capacity
Core Design Contradiction:
Loss of energyVSQuantity of substance

Solution Approach 1:

The storage capacity is segmented between two types of drives: low-power drives for caching frequently accessed data and high-capacity drives for bulk storage. This segmentation allows the system to achieve low power consumption for critical operations while maintaining adequate total storage capacity through the high-capacity drives, resolving the contradiction between energy efficiency and storage volume.

Inventive Principle:
Principle #1Segmentation
