Supported Raid Configurations - Quantum DXi4700 User Manual

Chapter 1: System Description

Supported RAID Configurations

(LSUs), which are similar to directories in a NAS file system or tape cartridges in a VTL partition.
The OST presentation requires the Veritas 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 Veritas 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.

Supported RAID Configurations

RAID is short for Redundant Array of Independent (or Inexpensive) Disks, which is a category of storage
that employs two or more drives in combination for fault tolerance and performance. There are a number of
RAID levels in use today such as 0, 1, 3, 5, 6 and 10. The DXi4700 uses RAID 6.
