Administrator Guide

When using cascaded replication for replications that are not alike, a replication can be limited when the different replication is
not a cascaded replication.
Display One-to-Many and Cascaded Replications
About this task
A NAS administrator can determine that one-to-many and cascaded replications is configured by noticing the following change
for a volumes:
● The same NAS volume is in the replication source list and replication destination list
●
NAS volume status has a new possible status: source and destination
● A table of both replications and status for each replication instead of only one or the other
Steps
1. In the Storage view, select a FluidFS cluster.
2. Click the File System tab.
3. In the File System view, expandReplications and then select a cluster.
The right pane displays the NAS volumes that are defined as the source and destination of the replication.
Add Replication for a NAS Volume
Adding replication creates a replication relationship between a source NAS volume and a target NAS volume. After adding
replication, you can set up a replication policy to run according to a set schedule or on demand.
Steps
1. In the Storage view, select a FluidFS cluster.
2. Click the File System tab.
3. In the File System view, expand NAS Volumes and select a NAS volume.
4. Click Create Replication. The Create Replication wizard starts.
If Inline Data Reduction for Replication Optimization is enabled, NAS volume replication will try to optimize network
utilization by reducing the amount of data copied. Dell recommends either Conditional Compression or Deduplication
and Conditional Compression as the inline data reduction method because it dynamically enables compression for in-flight
data based on system utilization. This option is completely independent of normal FluidFS data reduction (dedupe and
compression). Data that is already reduced is rehydrated and then reduced in-flight on its way to the remote destination.
5. Select a remoteFluidFS cluster, a policy from Snapshot Retention Policy at the destination, and a node from Limit
Replication Bandwidth According to QoS node (if enabled), and then click Next.
The Select Remote NAS Volume page opens.
6. Specify a target NAS volume using one of the following options:
● Select an existing NAS volume on the target FluidFS cluster.
● Create a NAS volume on the target FluidFS cluster.
Click Create Remote Volume. The Create NAS Volume dialog box opens. In the Name field, type a name for the NAS
volume. In the Size field, type a size for the NAS volume that is the same size or larger than the source NAS volume.
In the Folder field, select a parent folder for the NAS volume. Click OK to close the dialog box, then select the newly
created NAS volume.
7. Click Finish.
Delete Replication for a NAS Volume
Deleting replication for a NAS volume is similar to disabling replication for a NAS volume in that it does not disrupt replication
operations for other NAS volumes or the replication partnership between the source and target FluidFS clusters. After deleting
replication, the target NAS volume becomes a standalone, writable NAS volume. You can delete replication from either the
source or target FluidFS cluster.
