CommonProductProgrammingDistributed File SystemHigh-Performance Computing

3FS is a high-performance distributed file system designed for AI training and inference workloads. Leveraging modern SSDs and RDMA networks, it provides a shared storage layer, simplifying distributed application development. Its core advantages include high performance, strong consistency, and support for various workloads, significantly improving AI development and deployment efficiency. This system is suitable for large-scale AI projects, particularly excelling in data preparation, training, and inference stages.

High Performance: Combines the throughput of thousands of SSDs and the network bandwidth of hundreds of storage nodes to support large-scale parallel access.
Strong Consistency: Employs the CRAQ protocol to ensure strong data consistency
simplifying application development.
Support for Multiple Workloads: Suitable for scenarios such as data preparation
training sample loading
checkpoint saving
and inference caching.
Ease of Use: Provides standard file interfaces
eliminating the need to learn new storage APIs.
High Scalability: Supports large-scale cluster deployments to meet the needs of AI projects of various sizes.

3FS is ideal for AI developers and research teams requiring high-performance storage solutions
especially those handling massive datasets and complex model training. It significantly improves data processing efficiency and reduces development and deployment costs.

In large-scale AI training
3FS is used to store and quickly access training data
significantly improving training speed.
During the inference stage
3FS's KVCache function provides efficient caching support for LLM inference
