Remote Replication Concepts
FIGURE 31
Normal Replication Data Path
Assume that controller T2 has been taken down for a maintenance. T1 performed a takeover and
now owns all of the resources. If replication updates for projects Blue and Green are in progress
during the takeover, they will be canceled. After T1 takes over, these replication updates can be
resumed manually, or they will be resumed automatically if schedules are configured for the
corresponding replication actions.
After controller T1 has completed the takeover, it owns interfaces ixgbe2 and ixgbe4 which
are necessary to continue replication updates for projects Blue and Green. The following figure
shows the replication data path after T1 completed the takeover.
