Neutrino AI Storage

Purpose-engineered storage primitives that keep your GPUs fed, your checkpoints safe, and your pipelines moving at maximum speed.

High-speed dataset streaming

Feed datasets to your GPU cluster at maximum speed, ensuring faster training cycles and low-latency model inference. No bottlenecks. No idle GPUs.

Rapid checkpoints

Achieve the highest AI infrastructure goodput by employing high-speed shared storage for writing and reading checkpoints during multi-host distributed training.

Ready for multi-modality

Store any volume of unstructured data — from text corpora to raw video — to streamline operations for multi-modal AI training at petabyte scale.

Neutrino AI Object Storage

Fully S3-compatible object storage capable of storing static data, serving it to external consumers, and providing high-performance data streaming for MLOps scenarios.

Standard Class

Capacity-focused storage

  • Capacity-focused object storage buckets
  • Great for storing large volumes of unstructured data
Enhanced Class

Performance-focused storage

  • Performance-focused object storage buckets
  • Great for streaming data to GPU and checkpointing

* Depends on data structure, write concurrency, and upload process configuration.
