Preface

StorNext provides high performance data sharing and intelligent archiving that is compatible with an industry-leading range of operating systems, server platforms, and storage devices.

StorNext includes two main components:

•StorNext File System (SNFS) is high performance data sharing software that lets applications on multiple operating systems access a single data set.

•StorNext Storage Manger (SNSM) is an intelligent, policy-based data mover that automatically moves and locates data across multiple storage tiers.

You can choose to install both StorNext File System and Storage Manager, or install StorNext File System only. In addition, StorNext includes client software that allows client systems to mount and work with StorNext file systems.
