StorNext File System (SNFS), colloquially referred to as StorNext is a shared disk file system made by Quantum Corporation. StorNext enables multiple Windows, Linux and Apple workstations to access shared block storage over a Fibre Channel network. With the StorNext file system installed, these computers can read and write to the same storage volume at the same time enabling what is known as a "file-locking SAN." StorNext is used in environments where large files must be shared, and accessed simultaneously by users without network delays, or where a file must be available for access by multiple readers starting at different times. Common use cases include multiple video editor environments in feature film, television and general video post production.
