Administrator Guide

Provides throughput that is significantly better than CIFS or NFS
RDA with OST and DMA integration:
OpenStorage API enables the DMA-to-media server software communications
DR Series system storage capabilities can be used without extensive changes to DMAs
Backup and replication operations are simplified by using built-in DMA policies
DR Series system and RDA with OST:
Control channel uses TCP port 10011
Data channel uses TCP port 11000
Optimized write operations enable client-side deduplication
Replication operations between DR Series systems:
No configuration required on source or target DR Series systems
Replication is file-based, not container-based
Triggered by DMA optimized duplication operation
DR Series system transfers the data file (not the media server)
After duplication, DR Series system notifies DMA to update its catalog (acknowledging the second backup)
Supports different retention policies between source and replica
Software Components and Operational Guidelines
To better coordinate and integrate OpenStorage Technology (OST) with the DR Series system data storage operations,
the following guidelines list the required components and supported operations. For details on the supported operating
systems and DMA versions, see the
Dell DR Series System Interoperability Guide
.
The Dell DR Series system licensing is all-inclusive, so that no additional Dell licensing is required to use OST or the
optimized duplication capability. The Dell OST plug-in that gets installed on a supported Linux or Windows media server
platform is a free download from Dell. However, Symantec NetBackup requires that you purchase a Symantec
OpenStorage Disk Option license. Similarly, Symantec Backup Exec requires that you purchase the Deduplication Option
to enable the OST feature.
OST Media Server Component:
An OST server component resides on the DR Series system
For Linux media server installations, use the Linux OST plug-in and the Red Hat Package Manager (RPM)
installer
For Windows media server installations, use the Windows OST plug-in and the Microsoft (MSI) installer
Windows-based OST plug-in
Linux-based 64-bit OST plug-in
