Introduction to AI Advancements
The rapid growth of artificial intelligence has led to increasing data volumes and computational needs. AI training and inference require substantial computing power and storage solutions capable of handling large-scale, simultaneous data access. Traditional file systems often struggle with high data throughput, causing performance issues that can delay training cycles and increase inference latency.
Challenges in Current Systems
In distributed environments with numerous compute nodes accessing data at once, it is essential to have a storage system that provides low-latency access and reliable scalability. This is particularly vital for modern AI pipelines that process vast datasets and real-time data operations.
Introducing Fire-Flyer File System (3FS)
DeepSeek AI has developed the Fire-Flyer File System (3FS), a distributed file system designed to meet the specific needs of AI workloads. Optimized for modern SSDs and RDMA networks, 3FS offers a shared storage layer ideal for developing distributed applications. Its architecture combines the throughput of thousands of SSDs with the network capacity of numerous storage nodes, allowing for flexible and efficient data management.
Technical Details and Benefits
3FS features a disaggregated architecture that enhances large-scale data access while overcoming limitations of traditional file systems. It utilizes Chain Replication with Apportioned Queries (CRAQ) to ensure data consistency, simplifying application logic and maintaining system reliability even under high concurrency or node failures.
The system incorporates stateless metadata services supported by a transactional key-value store, enhancing scalability and reducing bottlenecks related to metadata operations. This separation allows for efficient metadata management as data volumes increase.
For inference workloads, 3FS features a cost-effective caching mechanism called KVCache, which provides high throughput and larger cache capacity compared to traditional DRAM-based caching. This is particularly beneficial for AI applications requiring repeated access to previously computed data.
Performance Benchmarks
3FS has undergone extensive benchmarking. In one test with 180 nodes, it achieved a read throughput of approximately 6.6 TiB/s while managing background traffic from training operations. Another test demonstrated its sorting capability, processing 110.5 TiB of data in just over 30 minutes, achieving an average throughput of 3.66 TiB/min.
The KVCache feature also showed significant performance, reaching a peak read throughput of 40 GiB/s during inference tests, effectively reducing latency for AI systems.
Conclusion
DeepSeek AI’s Fire-Flyer File System (3FS) effectively addresses the challenges of modern AI workflows by focusing on scalability, consistency, and efficient data access. Its innovative architecture and features position it as a leading solution for distributed AI storage needs. The impressive performance benchmarks confirm its capability to handle large data volumes efficiently, making 3FS a robust tool for today’s data-intensive AI applications.
