AMASS

AMASS transforms a device typically considered as “off-line storage” into truly on-line direct access mass storage. AMASS presents your automated optical or tape library as one device and one mount point, with a standard UNIX file system consisting of directories and files. A user or application can write files to or read files from the library the same way they would with the magnetic disk.

Advantages of using AMASS

  • Provides direct access to optical and tape storage libraries
  • Increases overall system performance because the data is written to the media in a contiguous stream
  • Delivers more efficient data management by allowing the many pieces of media to be divided into sets called volume groups
  • Enhances disaster recovery with automatic backup of the AMASS index to media in the library and a fully synchronized journal
  • Enables you to match the media to the application through its support of over 20 different vendors’ optical and tape libraries

AMASS is a file system implemented through the UNIX virtual file system layer. It’s completely transparent single filesystem interface and unlimited filesystem size can provide direct file access and storage on libraries of any size.Because AMASS presents the entire library under a single, exportable mount point, files are accessible via standard communication protocols such as NFS, TCP/IP, RFS, NetWare, AppleShare, LAN Manager and others.AMASS provides file, volume, drive, and automated library management and system administration tools needed to control, configure and monitor the system.

AMASS treats all media or volumes in the library as one large disk. An on-line AMASS index keeps track of where files are located on different volumes both in and out of the library. The capacity of the AMASS file system is virtually limitless. Maximum UNIX file size is supported and, when necessary, files and directories can span volumes.

  • Supports standard UNIX commands
  • Utilizes high-speed magnetic disk caching to reduce contention and increase performance
  • Utilizes on-line index to track file information allowing many common UNIX file operations to be completed without having to load a volume
  • Utilizes a motif-based Graphical User Interface (GUI) for system administration
  • Supports multiple heterogeneous libraries simultaneously (optical and tape)
  • Prioritizes reads over writes
  • Manages file, volume and drive operations automatically
