Subcluster Configuration Remote Cluster Configuration When you deploy multiple DX Storage Clusters (for example, multiple sites, offsite backup, and so on), the DX Cluster Services Node provides the ability to replicate data between DX Storage Clusters using the DX Content Router software. The DX Content Router provides two services: • Publisher service • Replicator service Clusters are connected by one cluster's replicator service to another cluster's publisher service. This link can either be one-way (for offsite backup) or two-way (for mirrored configurations). Each publisher can support a number of replicators with a specific set of replication rules. The publisher does not provide the same set of data objects to each replicator. For redundancy, more than one DX Cluster Services Node may be present in a cluster, but only one DX Cluster Services Node can be active as a publisher at any time. 11

Figure 3. Subcluster Configuration
Remote Cluster Configuration
When you deploy multiple DX Storage Clusters (for example, multiple sites, offsite backup, and so on), the DX Cluster
Services Node provides the ability to replicate data between DX Storage Clusters using the DX Content Router software.
The DX Content Router provides two services:
•
Publisher service
•
Replicator service
Clusters are connected by one cluster's replicator service to another cluster's publisher service. This link can either be
one-way (for offsite backup) or two-way (for mirrored configurations).
Each publisher can support a number of replicators with a specific set of replication rules. The publisher does not
provide the same set of data objects to each replicator.
For redundancy, more than one DX Cluster Services Node may be present in a cluster, but only one DX Cluster Services
Node can be active as a publisher at any time.
