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.
The OST presentation requires the Symantec NetBackup (6.5.3 or later)
or Backup Exec 2010 or later host application and the OST Plug-in client
installation on the media server. 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.
