| contents | Hybrid Solid-State Drives (SSDs), which integrate several types of flash cells (e.g., single-level cell (SLC) and multiple-level cell (MLC)) in a single drive and enable them to convert between each other, are designed to deliver both high performance and high storage capacity. However, compared to traditional SSDs, hybrid SSDs also introduce a much larger design space, resulting in higher optimization complexity due to more design factors involved, including flash conversion timing and data migration between different flash cells, etc. To address these challenges, large language models (LLMs) could be a promising technique, as they excel in handling complex, high-dimensional parameter space exploration by leveraging their advanced capability to identify patterns and optimize solutions. Recent works have started exploring the use of LLMs to optimize computer systems. However, to the best of our knowledge, no study has focused on optimizing SSDs with the assistance of LLMs.
In this work, we explore the potential of LLMs in understanding and efficiently managing hybrid SSD design space. Specifically, two important questions are exploited and analyzed: 1) Can LLMs offer optimization potential for Hybrid SSD management? 2) How to leverage LLMs for the performance and efficiency of hybrid SSD optimization? Based on the observations of exploration, we propose a comprehensive auto-tuning framework for hybrid SSDs, integrating LLMs to recommend customized configurations using calibration prompts derived from hardware, system, and workload information. Experimental results reveal a 62.35% improvement in throughput and a 57.99% decrease in write amplification compared to the default hybrid SSD configurations achieved with the incorporation of LLMs. |
