About Parallel File System

Parallel File System (PFS), a sub-product of OBS, is a high-performance file system, with only milliseconds of access latency. PFS can support terabytes of bandwidth and can handle millions of IOPS, which makes it ideal for processing high-performance computing (HPC) workloads.

You can access data in a parallel file system using standard OBS APIs. It also supports data read and write through obsfs, a PFS client that supports POSIX. obsfs can be deployed on a Linux ECS, and then you can use obsfs to mount a parallel file system to that server. Once mounted, PFS functions like a local file system. You can manage the PFS online, including creating, deleting, renaming files and folders, or modifying files.
