ABSTRACT:
A system for object-based archival data storage includes an object-based storage subsystem having respective data storage devices, at least one file presentation interface that interfaces to client platforms, an administration interface having graphical user interface (GUI) and a command line interface (CLI), a meta data subsystem for storing meta data about files, and includes a virtual file subsystem having a virtual file server (VFS), a policy subsystem that provides system rules predetermined by a user, and a scalable interconnect to couple the object-based storage subsystem, the at least one file presentation interface, the administration interface, the meta data subsystem, and the policy subsystem, wherein the meta data subsystem stores meta data about data files and object files including local file system location, object identification for data, hash, and presented file system information.
