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 sending replicated data to the
selected target.
• To resume replication, select a target under Target DXis and click
Resume . The DXi resumes sending replicated data to the selected
target.
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.
Note:
If multiple targets are configured, replication to all targets
counts against the same bandwidth limit.
Note: To vary the replication throttle rate over time, use the
Configuration > Scheduler page (see Scheduler on
page 292). Do not enable a constant throttle if a throttle
schedule is configured. The 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 Figure 140 ).
