Multi-Channel Solid-State Storage Parallel Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data storage systems using multiple solid-state storage devices face limitations in data transfer performance, as the transfer rate is often restricted by the individual devices, and frequent erasure operations reduce the lifespan of storage devices.
Innovation Solution
A data management system that transfers data segments in parallel across multiple storage devices while ensuring each data sector is updated and erased only in its designated device, reducing the number of erasure operations and optimizing data transfer rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If data is distributed across multiple storage devices to increase storage capacity, then storage capacity is improved, but data transfer rate is limited by individual device performance
Solution Approach 1:
The patent divides data into multiple segments and distributes them across multiple storage devices. Each storage device handles a portion of the data simultaneously, allowing parallel processing and improving overall data transfer rate while maintaining increased storage capacity.
Solution Approach 2:
The patent combines the capabilities of multiple storage devices by implementing a parallel data transfer architecture where multiple devices work together simultaneously. The host system can access multiple storage devices in parallel, merging their individual transfer rates to achieve a collective data transfer rate that exceeds that of any single device.
2Quantity of substance
If data sectors are distributed across multiple storage devices, then storage capacity is increased, but the number of erasure operations increases reducing device lifespan
Solution Approach 1:
The patent segments data into data units that can be independently managed. By organizing data at the data unit level rather than distributing individual sectors across devices, the system reduces the scope of erasure operations needed when updating data.
Solution Approach 2:
The patent implements preliminary organization of data into units before distribution. This allows the system to track which data units are located on which storage devices, enabling targeted updates without requiring widespread erasure operations across multiple devices.
Data Source
AI summary
A data storage system includes a data management system that transfers data between a host system and multiple storage devices through multiple channels. The data management system receives data from the host system and writes the data as data segments to the multiple storage devices. Each data segment may comprise one sector, more than one sector, or a portion of a sector, depending on the embodiment. The data segments are transferred to and from the multiple storage devices in parallel fashion while the data in each data segment is transferred to its corresponding data storage device sequentially. The data management system reassembles data segments received from the data storage devices and sends the data to the host system.
