Hierarchical File System Considerations › Types of File System

Types of File System

UNIX System Services implements the following types of hierarchical file systems:

HFS

HFS (Hierarchical File System) is the original implementation for USS. Data is physically stored in VSAM files, which are mounted to correspond to a certain directory path.

zFS

zFS (z/OS File System) is a newer implementation that can provide better performance and reliability, especially in environments where the file system is shared across multiple z/OS systems.

NFS

NFS (Network File System) is an implementation that allows a file system to be shared across a network.

ReportCenter can use any of these implementations. For simplicity, the examples in this guide always refers to HFS; you may substitute HFS with zFS or NFS.
