Optimized for AI Workloads

3FS is specifically designed to handle the unique demands of AI training and inference at scale.

High Performance

Achieve unprecedented throughput and low latency for large-scale model training with our optimized data access patterns.

Scalability

Seamlessly scale from single-node deployments to thousands of nodes without performance degradation.

Fault Tolerance

Automatic data replication and recovery ensure training jobs continue even with node failures.

Memory-Centric

Intelligent caching and prefetching minimize disk I/O bottlenecks during training iterations.

Random Access

Efficient random access patterns optimized for shuffling large datasets during training.

Framework Integration

Native support for TensorFlow, PyTorch, and other popular ML frameworks with minimal configuration.

Architecture Overview

3FS is built with a modular architecture that separates control and data planes for optimal performance.

Metadata Service Data Node 1 Data Node 2 Data Node 3 Client 1 Client 2 Client 3 Client 4 Legend Control Data Client

Metadata Service

Manages file system namespace, access control, and coordinates data placement across the cluster.

Data Nodes

Store actual file data with intelligent block placement and replication for fault tolerance.

Client Library

Provides POSIX-like interface with optimizations for AI workloads, including prefetching and caching.

Benchmark Results

3FS outperforms traditional distributed file systems for AI workloads.
