Best Practices: RDA with OST and the DR Series System

Best Practices: RDA with OST and the DR Series System

This topic introduces some recommended best practices for using RDA with 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

Setting client-side optimization

Client-side optimization (also known as client-side deduplication) is a process that can contribute to saving time performing backup operations and reducing the data transfer overhead on the network.

To configure dedupe/passthrough before the client makes a connection, you need to use the DR Series system command line interface (CLI).

 
NOTE: To update a client in the DR Series system GUI, the client must already be attached (and therefore enabled to appear in the GUI). If a client connection exists, you can select the radio button in the GUI to modify it.

You can turn client-side optimization On or Off by using the CLI commands, rda --update_client --name --mode. For more information about DR Series system CLI commands, see the DR Series System Command Line Reference Guide.

Configuring an LSU

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).
 
NOTE: For general information about creating DR Series system containers, see Creating Containers, and for creating an OST connection type container, see Creating an OST or RDS Connection Type Container.
 
NOTE: The capacity option in this command example sets the quota on the LSU. This is the maximum number of bytes (ignoring optimization) that can be written to an LSU and it is listed in the gigabytes (GB). If the capacity option is not specified (or if 0 is specified for the capacity), then the LSU will not have a quota. If this is the case, then this means that the amount of data that can be written to the LSU is limited only by the amount of free space on the disk.

Installing the RDA with OST plug-in

Installing the RDA with OST plug-in

Installing the RDA with OST plug-in for Backup Exec on Windows
Installing the RDA with OST plug-in for NetBackup on Windows
Uninstalling the RDA with OST plug-in for Windows
Installing the RDA with OST plug-in for NetBackup on Linux
Uninstalling the RDA with OST plug-in for Linux

Before you can start the installation process for the RDA with OST plug-in, you need to understand its role. The plug-in must be installed on to the media server type you choose. (For details on supported platforms, see the DR Series System Interoperability Guide.) The RDA with OST plug-in software enables integration between DR Series system data storage operations and the supported data management applications (DMAs).

Understanding the RDA with OST Plug-in (Linux)

The plug-in must be installed on the designated Linux-based media server running the support Linux server operating system software in the following directory: /usr/openv/lib/ost-plug-ins. The RDA with OST plug-in is installed using a self-extracting installer that installs the plug-in and all of its related components. The installer supports the following modes, with the default being Help (-h):

 
NOTE: If no option is selected, the Help mode is displayed by default.
•
Help (-h)
•
Install (-install)
•
Upgrade (-upgrade)
•
Uninstall (-uninstall)
•
Force (-force)
$> ./DellOSTPlugin-xxxxx-x86_64.bin -help
Dell plug-in installer/uninstaller
usage: DellOSTPlugin-xxxxx-x86_64.bin [ -h ] [ -install ] [ -uninstall ]
-h : Displays help
-install : Installs the plug-in
-upgrade : Upgrades the plug-in
-uninstall : Uninstalls the plug-in
-force : Forces the installation of the plug-in

You can download the RDA with plug-in installer from the Quest website as follows:

•
Go to support.quest.com/dr-series, select your specific DR Series model and then navigate to Software Downloads.
•
Locate the RDA with OST plug-in for Linux and download it to your system.

After it is downloaded, run the RDA with OST plug-in installer to install the plug-in on your designated Linux-based media server.

 
NOTE: The RDA with OST plug-in must be installed on client systems to support client-side deduplication.

Understanding the RDA with OST Plug-in (Windows)

The RDA with OST plug-in must be installed in the following directory on the designated Windows-based media server running the supported Microsoft Windows server operating system software: $INSTALL_PATH\VERITAS\Netbackup\bin\ost-plug-ins for NetBackup installations, and $INSTALL_PATH\Symantec\Backup Exec\bin\ for Backup Exec installations. After it is downloaded, you can use SETUP to install the RDA with OST plug-in.

 
NOTE: The RDA with OST plug-in must be installed on client systems to support client-side deduplication.
