This article provides information on a set of recommended best practices when deploying Data Domain storage systems for data protection and archive with the NFS (Network File System) protocol. This paper will provide insights on how to best tune NFS network components in order to optimize the NFS services on a Data Domain system. Best practices on configuring the NFS server, application clients, network connectivity and security.
- Network file system (NFS) protocol originally developed by Sun Microsystems in 1983 is a client-server protocol, allowing a user on a client computer to access files over a network from the server as easily as if the network devices were attached to its local disks.
- NFS allows UNIX systems to share files, directories and files systems. The protocol is designed to be stateless.
- Data Domain support NFS version 3 (NFSv3) the most commonly used version. It uses UDP or TCP and is based on the stateless protocol design. It includes some new features, such as a 64-bit file size, asynchronous writes and additional file attributes to reduce re-fetching.
