The z/OS™ Network File System (NFS) is a network file system product that brings IBM® leading-edge, system-managed storage to the network environment. It lets you optimize efficiency in a distributed network while still capitalizing on the capacity, security, and integrity of z/OS multiple virtual storage (MVS).
Use z/OS NFS for file serving (as a data repository) and file sharing between platforms supported by z/OS.
Use NFS to remotely access both conventional MVS data sets and UNIX® files. These remote MVS data sets or z/OS UNIX files are mounted from the mainframe to appear as local directories or files on the client system. As a result, you can bring the resources of an MVS system (such as system-managed storage, high-performance storage access, file access security, and centralized data access) to client platforms, with the option of data encryption.
The data set organizations that z/OS NFS supports include physical sequential (PS), direct access (DA), partitioned data sets (PDS), partitioned data sets extended (PDSE), VSAM KSDS, VSAM ESDS, VSAM RRDS, SAM extended format data sets, EAV and multivolume data sets. Both SMS-managed and non-SMS-managed data sets are supported. z/OS NFS does not support tape and optical drives, nor does it support generation data sets or multi-volume striped data sets.
The z/OS NFS server is used with an NFS client which allows remote applications on other servers to access z/OS data. Tested clients for the z/OS NFS server include:
- Linux (Red Hat Enterprise Linux and SUSE Linux Enterprise Server)
- Microsoft Windows with OpenText Maestro NFS
Other client platforms should work as well, since NFS version 4 is an industry standard protocol, but have not been tested by IBM. Older versions of the listed clients are still supported under the NFS version 2 and version 3 protocols, but not all have been tested by IBM.
