StorNext File System (SNFS) is a shared disk file system made by Quantum Corporation. It is installed on hosts that are connected to the same disk array in a storage area network (SAN) . Client systems are not required to run the same operating system to access a shared filesystem containing StorNext data. As of January 2008, the operating systems with available client software are Microsoft Windows, Mac OS X (as Xsan developed by Apple), Red Hat Linux, SuSE Linux, HP-UX, Solaris, AIX, and IRIX.

StorNext is used in environments where large files must be shared by users without network delays, or where a file must be available for access by multiple readers starting at different times. An example of the former is analysis of real time satellite image data. An example of the latter is on-demand access of a movie stored on disk.

The original name was CentraVision File System (CVFS). It was created by MountainGate Imaging Systems Corporation to provide fast data transfer between Windows and IRIX computers. Advanced Digital Information Corporation acquired MountainGate in September 1999, added additional client types, and changed the name to StorNext File System. The first new clients were Solaris and Linux. In August 2006 Quantum acquired ADIC.

The StorNext File System is the foundation for Quantum's StorNext Storage Manager, a hierarchical storage management system that is used for data archival with a back end robotic tape library.
