Replication Configuration
1. Under Target DXis, select one or more targets to delete.
2. Click Pause to pause replication to the target.
3. Click Delete.
Note: The deleted target is not automatically removed from existing replication schedules. You must
edit scheduled events to remove the deleted target (see
Pausing or Resuming Replication to a Target
The source DXi controls the replication pause behavior.
To pause replication, select a target under Target DXis and click Pause. The DXi temporarily stops
l
sending replicated data to the selected target.
To resume replication, select a target under Target DXis and click Resume. The DXi resumes sending
l
replicated data to the selected target.
Additional Information
If namespace replication is paused midway through a replication job, the job will fail.
l
If namespace replication is paused before the replication job starts, the job will sit in the queue until
l
replication is resumed. When resumed the job will start and replication will occur.
Trigger replication can be paused midway through a replication job. When resumed the job will
l
continue from where it was paused.
Enabling System Throttling
Enable system throttling to limit the network bandwidth used for replication to all targets. When a constant
throttle is enabled, the DXi limits the amount of data it sends during source replication so that it does not
exceed the specified bandwidth.
Additional Information
If multiple targets are configured, replication to all targets counts against the same bandwidth limit.
l
To vary the replication throttle rate over time, use the Configuration > Scheduler page (see
l
Scheduler on page
scheduled replication throttling bandwidth settings take precedence over the constant throttle value.
(The currently active replication throttle rate appears on the Home page under Current Activity.)
To enable system replication throttling:
1. Under Target DXis, click the box next to Throttling.
The Replication Throttle window displays (see
