Single Port Replication
With single-port replication, communication for all involved components uses only one port. The single port infrastructure supports
communication over IPv4 and IPv6, and is opened on all controller IPs and client VIPs.
Single port replication provides the following features:
• Trusted cluster establishment
• File system communication using a single common replication port
• Replication management communication using a single common replication port
Replicating NAS Volumes
You can perform manual and scheduled replication operations, and pause, resume, delete, and monitor replication.
One-to-Many and Cascaded Replications
FluidFS replication supports one-to-many and cascaded replications.
This feature creates more complicated replication formations. For example, this feature supports:
• Multiple disaster recoveries for the same NAS volume
• Distribution of the same data to multiple destinations around the world
• Cascading the data from the production cluster to another cluster and replicating from this cluster to reduce the load on the
production cluster
One-to-Many
One-to-many replication connects a source NAS volume to multiple destination NAS volumes. A NAS volume can be connected as the
source NAS volume in more than one replication pair at the same time. The destination NAS volumes can be on different clusters. One-to-
many replications are independent and can be run in parallel.
Limitation
When using one-to-many replication, the destination NAS volume can consume more space than the source NAS volume because it has
more snapshots.
Cascaded
A NAS volume that is the destination of one replication can serve as the source NAS volume for another replication. The replication data
can be cascaded from a NAS volume to a second NAS volume and from it to a third NAS volume and so on. Multiple NAS volumes that
are connected in a cascaded replication can also include one-to-many replications.
Limitation
When using cascaded replication for replications that are not alike, a replication can be limited when the different replication is not a
cascaded replication.

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.
