OpenStorage (OST)

With the OST presentation, the DXi system presents storage servers to a Symantec NetBackup or Backup
Exec media server through a specific Symantec protocol. A storage server consists of logical storage units
(LSUs), which are similar to directories in a NAS file system or tape cartridges in a VTL partition.
The OST presentation requires the Symantec NetBackup (7.1.x or later) or Backup Exec 2010 R3 or later
host application and the OST Plug-in client installation on the media server.
Note: Windows 2012 64-bit requires Symantec NetBackup (7.6 or later) or Backup Exec 2014 or later.
Plug-in clients are host-OS dependent and are supplied by Quantum. To use the DXi in OST mode, you
must configure an OST storage server and LSUs on the DXi. You must also map the LSUs on the
NetBackup server so that NetBackup can perform backups and restore from them. Additionally, policies for
optimized duplication (OST replication) and OST direct to tape may need to be set on the NetBackup server.
