z/OS Distributed File Service zSeries File System is a POSIX-style hierarchical file system for IBM's z/OS zSeries operating system, a successor to that operating system's HFS.[1]
zFS technology was first released in 1995 as the Local File System, a lower layer of the DCE Distributed File System. It was available on MVS/ESA V5R2.2 and all OS/390 releases. DFS/LFS was provided as a part of the DCE feature, not of the base operating system.
zFS was initially released for z/OS as separate PTFs (patches) for z/OS 1.2, with backports available for z/OS 1.1 and OS/390 2.10. Beginning with z/OS 1.3, zFS is included as a standard feature and is being actively developed.
