In an active/active replication ring topology, multiple HCP systems are connected by active/active links where:
•Each system has exactly two active/active links that connect that system to two other systems in such a way that all the systems are linked in the form of a ring
•The same HCP tenants and namespaces and default-namespace directories are replicated on each link
An active/active replication ring can include any number of HCP systems. Changes made on one system travel around the ring in both directions from that system until they reach a system in which those changes have already occurred.
To configure an active/active replication ring topology:
1.Create an active/active link between each pair of systems in the ring.
2.For each system that has locally created tenants, namespaces, and directories you want to replicate, add those items to one of the links connected to that system.
3.After those tenants, namespaces, and directories have been replicated, add them to the second link that’s connected to the system to which the items have been replicated.
4.After the items have been replicated to that system, add them to the next link in the ring.
5.Continue adding the replicated items to successive links until you have added them to the second link that connects to the system on which the items were originally created.
What this looks like
The figure below shows an active/active replication ring topology that includes three systems (A, B, C, and D).
