AI training requires vast amounts of data, resulting in increasing storage costs. Object storage has gained attention due to its scalability and cost-effectiveness. However, direct usage of it brings certain challenges, including low metadata performance, lack of atomic rename operations, and eventual consistency issues. These challenges are particularly pronounced during the model training phase.
Simultaneously, containerization technology is trending. However, traditional distributed file systems lack horizontal scalability, making it difficult to support the extensive scalability of Kubernetes. Additionally, as computing is no longer limited to a fixed set of machines, data needs to intelligently "flow" with the movement of computational resources.
We aim to share our practical experience. We will explore how to optimize the storage layer's I/O efficiency in data caching, prefetching, concurrent reads, and scheduling while keeping the upper-layer components unchanged.
