How Long Does It Take for Data to Be Replicated to the Remote Storage System After a Pair Synchronization Is Started?

Note that a remote storage system is not equal to the secondary storage system. Data can only be replicated from the primary storage system to the remote storage system. Therefore, when the local storage system is the primary storage system, data of the local storage system can be replicated to the remote storage system after the replication pair is synchronized. However, when the local storage system is the secondary storage system, data cannot be replicated to the remote storage system after the pair synchronization.
The data replication time is determined by the following factors:
• The amount of data to be replicated (initial synchronization)
• The amount of data changed after the last synchronization (non-initial synchronization)
• Network bandwidth
• Performance of storage nodes and disks
• Number of storage nodes that participate in remote replication
• Workload of concurrent system tasks
• Replication transmission rate of a pair
