The Network File System (NFS) is a distributed file system protocol that allows a user on a client computer to access files over a network as if they were local files. NFS is a popular protocol for sharing files between Unix and Linux systems, and it is also supported by many other operating systems, including Windows and macOS. Solaris is a Unix-based operating system that has been developed by Oracle since 1993. NFS version 4 (NFSv4) is the latest version of the NFS protocol, and it offers several advantages over previous versions, including improved performance, security, and scalability. You can check the version of NFS that is running on a Solaris system by using the `nfsstat` command. You can check the version of NFS that is running on a Solaris system by using the `nfsstat` command.
NFSv4 is the recommended version of NFS for use with Solaris systems. It offers several advantages over previous versions, including improved performance, security, and scalability. If you are using an older version of NFS, you should consider upgrading to NFSv4 to take advantage of these benefits.
