Term LSU media server NBU OST Description 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. 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. Symantec DMA, NetBackup (NBU) 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). 125
