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 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 Rapid Data Access (RDA).
The RDA pane is displayed.
6.
In the RDA pane, set the RDA Type to Symantec OpenStorage (OST).
7.
In Capacity, select either the Unlimited or Size options to set the capacity for the OST connection type container.
If you select Size, make sure to define the desired size in Gibibytes (GiB).
8.
Click Create a New Container (or click Cancel to display the Containers page).
