Change Replication Throttling
To disable replication throttling on a QoS node:
Steps
1. In the Storage view, select a FluidFS cluster.
2. Click the File System tab.
3. In the File System view, click Replications.
4. Click the Replication NAS Volumes tab, select a replication, and then right-click.
5. Select Replication Actions.
6. From the drop-down list, select Edit Replication QoS.
7. Clear the Enable QoS checkbox to disable using a QoS node.
8. Click OK.
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.
