RDS Guidelines
For best results, observe the following guidelines for optimal performance with your supported RDS operations with the
DR Series system:
•
Back up, restore, and optimized duplication operations performed using the Dell ROFS plug-in
NOTA: The Dell ROFS plug-in is installed on client systems to support client-side deduplication.
•
Optimal supported aggregated throughput rates:
–
3.8 Terabytes per hour (TB/hr) for passthrough write operations
–
7.3 TB/hr for dedupe write operations
NOTA: Passthrough writes are when data is sent from a media server to the DR Series system without
applying any optimization to the data. By contrast, dedupe writes are when data is sent from a media
server to the DR Series system after optimization is applied to the data.
•
Backup:
–
Passthrough writes
–
Dedupe writes
•
Restore
•
Replication
Best Practices: RDS and the DR Series System
This topic introduces some recommended best practices for using Rapid Data Storage (RDS) operations with the DR
Series system.
RDS and non-
The DR Series system supports having both RDS and non-RDS containers on the same
RDS containers
appliance. However, this can cause incorrect capacity reporting as both container types share
can exist on the
the same underlying storage.

system
RDS replication
Non-RDS replication must be configured, and it is replicated on a per-container basis.
and non-RDS
However, this type of replication will not replicate RDS containers. RDS replication is file-
replication on the
based and is triggered by the DMA.

Do not change
A non-RDS container must be deleted before this container can then be created as an RDS

Setting Client-Side Optimization
Client-side optimization is a process that can contribute to saving time performing backup operations and reducing the
data transfer overhead on the network.
