- Version 2010 R3 (Windows 2008 R2, 64-bit) - Version 2012 (Windows 2008 R2, 64-bit) NOTE: The Dell DR Series system licensing is all-inclusive, so that no additional Dell licensing is required to use OST or the optimized duplication capability. The Dell OST plug-in that gets installed on a supported Linux or Windows media server platform is a free download from Dell. However, Symantec NetBackup requires that you purchase a Symantec OpenStorage Disk Option license.

OST Required Configurations This topic introduces three possible required configurations that must be made to enable OpenStorage Technology (OST) operations: DR Series system and a DMA-based media server or client (for example, OST operations that support a NetBackup-media server, a Backup Exec-media server, or a Backup Exec-client). Best Practices: OST and the DR Series System This topic introduces some recommended best practices for using OpenStorage Technology (OST) operations with the DR Series system. • OST and non-OST containers can exist on the same DR Series system. The DR Series system supports having both OST and non-OST containers on the same appliance. However, this can cause incorrect capacity reporting as both container types share the same underlying storage. • OST replication and non-OST replication on the same DR Series system. Non-OST replication needs to be configured, and it is replicated on a per-container basis. However, this type of replication will not replicate OST containers. OST replication is file-based and is triggered by the DMA. • Do not change the container connection type from NFS/CIFS to OST. A non-OST container must be deleted before this container can then be created as an OST container using the same name. Setting Client-Side Optimization Client-side optimization is a process that can contribute to saving time performing backup operations and reducing the data transfer overhead on the network. You can turn On or turn Off client-side optimization (also known as client-side deduplication) using the DR Series system CLI commands, ost --update_client --name --mode. For more information about DR Series system CLI commands, see the Dell DR Series System Command Line Reference Guide, which is available at support.dell.com/manuals. Configuring an LSU You can configure a logical storage unit (LSU) as an OpenStorage Technology (OST) connection type container for data storage by using the DR Series system GUI. To configure an LSU as an OST connection type container, log in to the DR Series system and complete the following: 1. Navigate to the Containers page (in the Dashboard navigation panel). 2. Click Create to create a new container. The Create New Container dialog is displayed. 3. In Container Name, enter a name for the container. 4. In Marker Type, select the None marker type. For OST operations, only the NetBackup and Backup Exec media servers are supported. 5. In Connection Type, set the container type to OST. 131

NOTE:
The Dell DR Series system licensing is all-inclusive, so that no additional Dell licensing is required to use
OST or the optimized duplication capability. The Dell OST plug-in that gets installed on a supported Linux or
Windows media server platform is a free download from Dell. However, Symantec NetBackup requires that you
purchase a Symantec OpenStorage Disk Option license. Similarly, Symantec Backup Exec requires that you
purchase the Deduplication Option to enable the OST feature.
OST Required Configurations
This topic introduces three possible required configurations that must be made to enable OpenStorage Technology
(OST) operations: DR Series system and a DMA-based media server or client (for example, OST operations that support
a NetBackup-media server, a Backup Exec-media server, or a Backup Exec-client).
Best Practices: OST and the DR Series System
This topic introduces some recommended best practices for using OpenStorage Technology (OST) operations with the
DR Series system.
•
OST and non-OST containers can exist on the same DR Series system. The DR Series system supports having
both OST and non-OST containers on the same appliance. However, this can cause incorrect capacity reporting
as both container types share the same underlying storage.
•
OST replication and non-OST replication on the same DR Series system. Non-OST replication needs to be
configured, and it is replicated on a per-container basis. However, this type of replication will not replicate OST
containers. OST replication is file-based and is triggered by the DMA.
•
Do not change the container connection type from NFS/CIFS to OST. A non-OST container must be deleted
before this container can then be created as an OST container using the same name.
Setting Client-Side Optimization
Client-side optimization is a process that can contribute to saving time performing backup operations and reducing the
data transfer overhead on the network.
You can turn On or turn Off client-side optimization (also known as client-side deduplication) using the DR Series system
CLI commands,
ost --update_client --name --mode
. For more information about DR Series system CLI commands, see
the
Dell DR Series System Command Line Reference Guide
, which is available at

.
Configuring an LSU
You can configure a logical storage unit (LSU) as an OpenStorage Technology (OST) connection type container for data
storage by using the DR Series system GUI. To configure an LSU as an OST connection type container, log in to the DR
Series system and complete the following:
1.
Navigate to the
Containers
page (in the
Dashboard
navigation panel).
2.
Click
Create
to create a new container.
The
Create New Container
dialog is displayed.
3.
In
Container Name
, enter a name for the container.
4.
In
Marker Type
, select the
None
marker type.
For OST operations, only the NetBackup and Backup Exec media servers are supported.
5.
In
Connection Type
, set the container type to
OST
.
