Chapter 2. Replication Topologies
A replication topology is a defined arrangement between independent DX Storage clusters,
connected to one another via DX Content Router nodes. DX Content Router supports several
alternative replication topologies.

2.1. Disaster Recovery

DX Content Router allows an administrator to replicate some or all the streams stored in a primary
cluster to a disaster recovery site. In case of a complete failure or loss of the primary cluster, all
replicated streams can be recovered from the DR site. Hence, it is important that the administrator
carefully plan the type of content that should be replicated to the DR site.

2.2. Mirrored Clusters

DX Content Router allows mirroring between two or more primary clusters. All designated streams
stored in Cluster A will be replicated to Cluster B, and vice versa. The administrator of each cluster
can decide, based on stream metadata, which streams should be replicated to the other cluster. It is
possible that the two replication sets may identical, completely disjoint or have some overlap.

2.3. Multi-Site Disaster Recovery

Using a combination of one-way DR replication and mirrored clusters, more complex disaster
recovery topologies can be deployed. Such deployments rely upon a unique metadata identifier for
the origin of each object to ensure the correct subset of content is recovered from a pooled (many-
to-one) DR cluster in the event of a disaster. See Appendix I for an overview of the various means
by which metadata can be associated with streams in DX Storage. Some or all the DR sites may be
shared with other independent primary clusters. In case of loss of the primary cluster, all replicated
streams can be recovered from one or more DR clusters. This requires modification of the rules set
in the DR cluster and you should seek the assistance of your designated support resource.
