Term Description
LSU Logical Storage Unit, which from the DR Series system perspective,
represents any container created for data storage. LSU is a common
storage term while container is a common term in DR Series systems
that represents a location for storing data.
media server This is the host running the DMA media server and is where the RDA
with OST plug-in is installed. The RDA with OST plug-in can also be
installed on a client.
NBU Symantec DMA, NetBackup (NBU)
OST The OpenStorage Technology from Symantec, which allows storage
devices to deliver backup and recovery solutions with NetBackup. RDA
with OST uses the OpenStorage API and a plug-in installed on either a
Linux or a Windows-based media server platform.
Supported RDA with OST Software and Components
For the list of supported DMAs and DR Rapid plug-ins, see the Dell DR Series System Interoperability Guide , at
support.dell.com/manuals.
The Dell DR Series system licensing is all-inclusive, so that no additional Dell licensing is required to use RDA with OST
or the optimized duplication capability. The RDA with OST plug-in that gets installed on a supported Linux or Windows
media server platform is a free download from Dell. However, if you are using Symantec backup applications, you may
need to purchase additional licensing to enable OpenStorage Technology; refer to your Symantec documentation.
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
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 On or turn Off client-side optimization by using the CLI commands, rda --update_client --name --mode. For
more information about DR Series system CLI commands, see the Dell DR Series System Command Line Reference
Guide located at dell.com/powervaultmanuals (by selecting your particular DR Series system).
