HP-UX System Administrator's Guide: Overview

Remotely Mounted File Systems
HP-UX 11i version 3 implements several ways to share file systems and directories
between multiple computers. These include:
NFS NFS (Network File System) allows you to export file systems or directories
from a server to a pre-defined set of servers which in turn will mount the
exported file system so that users and processes of those servers can access
the remotely mounted file systems as if they were local file systems.
Samba Samba is an implementation of Microsoft’s SMB (Server Message Block)
protocol (and other protocols) that allows for a directory and its sub-directories
to be shared between multiple computers.
