StorageXTuner: An LLM Agent-Driven Automatic Tuning Framework for Heterogeneous Storage Systems
StorageXTuner is an LLM agent-driven automatic tuning framework for heterogeneous storage systems. It addresses limitations of prior LLM-based solutions by decomposing tuning into four collaborative agents: Executor (benchmarking), Extractor (performance digest), Searcher (config exploration), and Reflector (insight management). The framework employs an insight-driven tree search with layered memory for efficient exploration and robust validation, leading to significant performance improvements across diverse storage systems like RocksDB, LevelDB, CacheLib, and MySQL InnoDB, with up to 709% higher throughput and 88% lower p99 latency.
Executive Impact & Key Findings
StorageXTuner represents a significant leap in automated system tuning, delivering substantial performance gains and operational efficiencies across a variety of storage systems and workloads. Its multi-agent architecture and insight-driven approach set new benchmarks for reliability and cost-effectiveness in LLM-powered optimization.

Framework Architecture
StorageXTuner's core is a multi-agent framework: Executor (benchmarking), Extractor (performance digest), Searcher (config exploration), and Reflector (insight management). This decomposition ensures modularity, clear context for LLMs, and efficient workflow. Agents communicate iteratively, refining configurations and insights over time.
Insight Management
Reflector manages tuning insights using a layered memory: Short-Term Memory (STM) for tentative insights, and Long-Term Memory (LTM) for validated, reusable knowledge. A dynamic confidence score, updated via empirical feedback, ensures only reliable insights persist, guiding Searcher's exploration efficiently.
Evaluation Metrics
The framework introduces novel LLM-driven tuning metrics: Max Performance Gain (MPG), Token Cost to 95% Max Performance (TC95), Token Efficiency (TE), and Token-Weighted Error Rate (TWER). These quantify performance, LLM resource usage, cost-effectiveness, and robustness, providing a holistic view of tuning solution quality.
LLM Agent Collaboration
StorageXTuner's agents collaborate through iterative cycles. Executor runs benchmarks, Extractor synthesizes performance digests, Searcher proposes configurations guided by Reflector's insights, and Reflector updates insights based on Searcher's tuning experiences. This closed-loop feedback mechanism enhances learning and efficiency.

Operational Efficiency & Cost Reduction
StorageXTuner significantly reduces operational costs by achieving 95% of peak performance with 56K LLM tokens, compared to 138K for ELMo-Tune and 214K for LLM-Default (Table 3). This translates to lower API costs and faster convergence, requiring fewer iterations to reach optimal configurations. The closed-loop LLM reasoning and insight validation mechanisms prevent redundant trials and errors, minimizing human intervention and maximizing efficiency.

Implementation Roadmap
Our phased approach ensures a smooth transition and rapid value realization, integrating StorageXTuner into your existing infrastructure with minimal disruption.
Phase 1: Initial Assessment & Integration (1-2 Weeks)
Identify key storage systems (e.g., RocksDB, MySQL InnoDB), define performance goals, and integrate StorageXTuner with your existing monitoring and benchmarking tools. Initial LLM models are fine-tuned with system-specific documentation.
Phase 2: Baseline Establishment & Insight Generation (3-4 Weeks)
Run initial benchmarks with default configurations across diverse workloads. The Extractor agent generates performance digests, and the Reflector begins populating the Short-Term Memory with preliminary tuning insights.
Phase 3: Iterative Tuning & Optimization Cycles (4-8 Weeks)
The Searcher agent, guided by dynamic insights and tree-based exploration, iteratively proposes and evaluates configurations. Performance gains are observed, insights are validated (promoted to LTM), and the system converges towards optimal settings.
Phase 4: Continuous Learning & Adaptive Deployment (Ongoing)
Leverage the Long-Term Memory for cold-start acceleration and adaptive tuning as workloads or hardware change. StorageXTuner continuously learns from new data, maintaining peak performance with minimal human oversight.
