Parallel File System (PFS), a sub-product of OBS, is a high-performance file system, with access latency in milliseconds. PFS can support a bandwidth performance up to the TB/s level and supports millions of IOPS, which makes it ideal for processing high-performance computing (HPC) workloads.

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.

For details about PFS, see the Parallel File System Feature Guide.
