Parallel File System

Parallel File System (PFS) is a high-performance file system provided by OBS, with access latency in milliseconds. PFS supports TB/s-level bandwidth and millions of IOPS, making 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 an ECS, and then you can use the obsfs to mount a parallel file system to the Linux OS running on the ECS. The mounted parallel file system functions as a local file system. You can manage the mounted parallel file system online, including creating, deleting, renaming files and folders, as well as modifying files.
