Dell PowerVault MD Series Storage Arrays Storage Replication Adapter (SRA) Best Practices Guide (Client)

Remote replication groups require a 10-minute interval between automatic and manual synchronizations. If you request a manual synchronization when a Remote Replication group is inside a 10-minute synchronization interval, the manual synchronization does not begin until the previous synchronization interval has passed. This interval may cause a delay in the SRM workflow process which requires several synchronization operations to occur during test failover and/or failover workflows. SRA is optimized to avoid requesting a manual synchronization if no changes are detected within the Remote Replication group. However, if changes are detected, a synchronization is requested. The effect may be observed as a lack of progress or slow progress through SRM workflows.
