FMS 2024: DapuStor Extends Collaboration with Marvell to Unveil Flexible Data Placement Technology for QLC SSDs

DapuStor Corporation is expanding its collaboration with Marvell Technology, Inc. to deliver Flexible Data Placement (FDP) technology optimized for QLC and TLC SSDs.

This collaboration aims to change the storage industry by addressing the inherent challenges of QLC SSDs, enhancing their performance, endurance, and capacity, thereby providing a robust and cost-effective solution for data centers, cloud computing, and high-performance computing environments.

Unlocking potential of QLC SSDs with FDP technology
QLC SSDs are renowned for their ability to store 4 bits of data/memory cell, offering significant capacity advantages and a lower TCO compared to other SSD types. Despite these benefits, they face challenges such as lower endurance and slower write speeds. The FDP technology supported in the Marvell Bravera SC5 SSD controller with firmware level solution developed by DapuStor directly addresses these issues.

FDP technology intelligently distributes data across the QLC flash memory, optimizing the use of available memory cells and minimizing the impact of write amplification. The FDP algorithms dynamically adjust data placement based on workload and usage patterns, ensuring that the most frequently accessed data is stored in the fastest and most durable regions of the SSD. This results in improved performance, extended endurance, and enhanced reliability.

High performance metrics with Marvell and DapuStor FDP solutions
Extensive testing has demonstrated that FDP algorithms integrated with the Bravera SC5 SSD controller and DapuStor firmware can achieve a write amplification (WA) close to 1.0. A WA of 1.0 indicates that the SSD is utilizing the NAND flash to its full endurance potential without wastage. This optimization ensures that the DapuStor QLC SSD H5000 series can perform at its highest possible efficiency.

In addition to intelligent data placement, the company’s FDP solutions incorporate advanced error correction and wear leveling techniques, further enhancing the endurance and reliability of QLC SSDs. These advancements enable QLC SSDs to achieve higher write speeds, lower latency, and a longer lifespan, making them for a range of demanding applications.

Advancing storage innovation and excellence
This announcement builds on the work that the 2 companies have achieved in bringing PCIe Gen 5 SSDs to market. The companies’ latest cooperation on FDP technology signifies an important milestone in opening new possibilities for QLC applications. By combining Marvell’s expertise in data center semiconductor solutions with DapuStor’s storage technologies, the collaboration is set to deliver unparalleled advancements in SSD performance and efficiency.

“Marvell is excited to extend our longstanding relationship with DapuStor in bringing innovative storage technologies to market,” said Matt Kim, VP, storage business, Marvell. “Our collaboration on FDP technology will unlock the full potential of QLC SSDs, providing our customers with higher capacity and performance storage solutions at a lower total cost of ownership.”

“We are thrilled to collaborate with Marvell in developing FDP solutions,” said John Li, VP, DapuStor. “This collaboration underscores our commitment to innovation and excellence in the storage industry. Together, we will set new standards for the DapuStor QLC SSD H5000 series’ performance and reliability.”

Showcase at FMS 2024
