Storage Systems for ML

Storage systems for ML is the data infrastructure designed to feed large-scale training and inference workloads with sustained high throughput - they must balance capacity, bandwidth, metadata performance, and cache strategy to prevent GPU starvation.

What Is Storage systems for ML?

• Definition: Storage architecture optimized for machine learning data access patterns across training and evaluation.
• Workload Types: Large sequential epoch reads, random sample access, checkpoint writes, and metadata-heavy file operations.
• Tiering Strategy: Combines object storage, parallel file systems, and local NVMe cache layers.
• Success Metrics: Read throughput, per-node latency, cache hit rate, and end-to-end GPU utilization.

Why Storage systems for ML Matters

• GPU Efficiency: Insufficient data throughput can leave accelerators idle despite available compute.
• Training Time: Storage bottlenecks increase step duration and extend total project schedule.
• Scalable Operations: Petabyte-scale datasets require architecture beyond traditional enterprise file shares.
• Reliability: Robust storage design protects model artifacts and dataset integrity.
• Cost Control: Tiered storage prevents overspending on premium media for cold data.

How It Is Used in Practice

• Access Profiling: Measure actual read/write and metadata behavior for target workloads.
• Tier Optimization: Place hot training shards on high-speed tiers and cold data on economical object layers.
• Continuous Tuning: Track pipeline stalls and rebalance storage and cache policies iteratively.

Storage systems for ML are the data-supply backbone of AI training performance - well-balanced storage design is required to convert GPU capacity into real model progress.
