A tiered storage strategy balances GPU memory speed against capacity for long-context inference.
Smart prefix design beats faster hardware for training pipeline throughput.
SSD endurance, not just capacity, determines whether KV cache offload saves money at scale.
Direct GPU storage access eliminates CPU bottlenecks that throttle LLM throughput at scale.
Pick the filesystem layer that matches your workload's I/O pattern, not just bandwidth.
Layered I/O bottlenecks slow distributed training checkpoints beyond hardware limits.
Identifying which storage bottleneck limits your inference load times.
Purpose-built storage must handle checkpoint writes and dataset reads separately.
GPU-to-NVMe I/O bottleneck lives in the CPU path, not the drive itself.
