Huawei Launches Major SSD Amid US HBM Export Challenges
Huawei has made a significant move in the AI storage market by introducing a new line of solid-state drives (SSDs) aimed at reducing reliance on high-bandwidth memory (HBM). The company unveiled the OceanDisk EX, OceanDisk SP, and the OceanDisk LC 560 during its Data Storage AI SSD launch event. These innovations are designed to tackle the challenges posed by the “memory wall” and “capacity wall,” which currently hinder the efficiency of artificial intelligence workloads.
Overview of the OceanDisk Series
The OceanDisk series includes three distinct models, each tailored for specific performance needs. The OceanDisk EX 560 is touted as an โextreme performance drive,โ boasting impressive write speeds of up to 1,500K IOPS and a latency of less than 7 microseconds. With an endurance rating of 60 drive writes per day (DWPD), this model is particularly suited for fine-tuning large language models (LLMs), as it can increase the number of adjustable model parameters on a single machine by six times.
In contrast, the OceanDisk SP 560 is designed with cost-effectiveness in mind. It offers a performance of 600K IOPS and a lower durability rating of 1 DWPD. This model is aimed at inference scenarios, claiming to reduce first-token latency by 75% while simultaneously doubling throughput. The OceanDisk LC 560 stands out as the largest SSD in the lineup, featuring a remarkable single-drive capacity of 245TB and a read bandwidth of 14.7GB/s. Huawei positions this model as ideal for managing extensive multimodal datasets during cluster training, although its practical application will depend on how well it integrates with existing systems.
Innovative Software Solutions
In addition to the hardware advancements, Huawei has introduced DiskBooster, a software driver designed to enhance pooled memory capacity by twentyfold. This software coordinates the new AI SSDs with both HBM and DDR memory, aiming to optimize performance across various applications. Furthermore, Huawei has highlighted its multi-stream technology, which seeks to minimize write amplification, potentially extending the lifespan of the drives.
These software-driven enhancements may offer greater flexibility for AI workloads, but the actual benefits will depend on how effectively applications can adopt and support these innovations. Huawei’s focus on software solutions complements its hardware offerings, creating a more comprehensive approach to addressing the challenges faced by AI systems.
Strategic Shift in Memory Technology
Huawei’s latest SSD launch is a strategic response to the ongoing restrictions imposed by the United States on advanced HBM chips, which have limited access for Chinese companies. By emphasizing the development of domestic NAND flash technology, Huawei aims to reduce China’s dependence on imported HBM chips and shift the focus toward high-capacity SSD solutions.
While these new drives are not intended to completely replace HBM, they serve as a partial alternative that could alleviate some of the demand for expensive memory solutions. Huawei argues that high-capacity solid-state storage, combined with specialized software, can help mitigate the constraints posed by HBM in LLM training. However, the effectiveness of this approach remains to be seen, as it will require thorough testing and validation in real-world applications.
