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
メモ: 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
メモ: 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-
RDS containers
can exist on the
same DR Series
system
The DR Series system supports having both RDS and non-RDS containers on the same
appliance. However, this can cause incorrect capacity reporting as both container types share
the same underlying storage.
RDS replication
and non-RDS
replication on the
same DR Series
system
Non-RDS replication must be configured, and it is replicated on a per-container basis.
However, this type of replication will not replicate RDS containers. RDS replication is file-
based and is triggered by the DMA.
Do not change
the container
connection type
from NFS/CIFS to
RDS
A non-RDS container must be deleted before this container can then be created as an RDS
container using the same name.
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.
