Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data storage solutions, such as hard disk drives, face slow data processing speeds and inefficient interfaces that fail to maximize the performance of high-speed memory disks, leading to suboptimal utilization of memory disk performance.
Innovation Solution
A hybrid storage system architecture that incorporates a hybrid RAID controller coupled with a system control board, DDR RAID controller, RAM RAID controller, and HDD/Flash RAID controller, along with DDR memory disks, RAM SSDs, and HDD/Flash SSD Units, utilizing PCI-Express technology to synchronize data signals and support both low-speed host data processing and high-speed memory disk operations.

Engineering Contradiction Analysis
1Speed
If high-speed memory disks are used, then data processing speed is improved, but interface performance cannot catch up, leading to suboptimal utilization
Solution Approach 1:
The storage system is segmented into multiple independent RAID controllers (SATA RAID controller, SAS RAID controller, Fibre Channel RAID controller) that can operate autonomously at different speeds. Each controller manages specific storage devices and can optimize data processing independently, allowing high-speed memory disks to be fully utilized without being bottlenecked by a single slow interface.
Solution Approach 2:
The patent introduces a hierarchical RAID controller architecture that adds a dimensional layer of control. Multiple RAID controllers operate at different levels (SATA level, SAS level, Fibre Channel level) simultaneously, enabling the system to exploit high-speed memory disk performance through parallel processing dimensions rather than being constrained by a single interface bottleneck.
2Productivity
If multiple types of storage devices are integrated, then storage capacity and performance are improved, but system complexity increases
Solution Approach 1:
The system segments storage devices by interface type and assigns dedicated RAID controllers to each segment (SATA devices to SATA controller, SAS devices to SAS controller, Fibre Channel devices to Fibre Channel controller). This segmentation isolates complexity to specific controllers while maintaining overall system functionality, allowing each controller to be optimized for its specific device type without affecting others.
Solution Approach 2:
Each RAID controller is designed with multi-functionality to handle not only its primary interface type but also to provide RAID functionality across different storage configurations. The controllers can operate independently or in coordination, providing universal RAID services while maintaining specialized optimization for each interface type, thus managing complexity through functional integration.
