Dell PowerVault DR6000 - Manual (Page 26)

– 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
• Supported Symantec OpenStorage (OST) protocol:
– Symantec, version 9
– Symantec, version 10
• Supported Symantec DMAs
– NetBackup
– Backup Exec
• Supported OST operations
– Backup (Passthrough writes and Optimized writes)
