Understanding RDA with OST

Understanding RDA with OST

OpenStorage Technology (OST) provides the logical disk interface that can be used with network storage devices, and the DR Series system appliance requires RDA with OST plug-in software to integrate its data storage operations with supported data management applications (DMAs). For details on the applications supported, see the DR Series System Interoperability Guide.

The DR Series system integrates with supported DMAs using the RDA with OST plug-in, through which DMAs can control when backup images are created, duplicated, and deleted. Via the plug-in, the DMAs can take full advantage of key DR Series system features like replication and data deduplication.

The DR Series system accesses the OpenStorage API code through the RDA with OST plug-in, which can be installed on the supported media server platform type that you choose (Windows or Linux). When RDA with OST is used with the DR Series system, it offers the following benefits:



For best results, observe the following guidelines for optimal performance with your supported RDA with OST operations with the DR Series system:



This topic introduces and briefly defines some basic RDA for OST terminology used throughout the DR Series system documentation.




Veritas DMA, Backup Exec (BE)


Data Management Application (also known as Data Protection Application), which are terms for the role played by the backup applications used with RDA with OST; for example, Veritas NetBackup or Backup Exec.


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.


Veritas 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

Supported RDA with OST software and components

For the list of supported DMAs and DR Rapid plug-ins, see the DR Series System Interoperability Guide.

The DR Series system licensing is all-inclusive, so that no additional 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. However, if you are using Veritas backup applications, you may need to purchase additional licensing to enable OpenStorage Technology; refer to your Veritas documentation.
