Scheduler
Scheduling Replication Throttling
During replication throttling, the ETERNUS CS800 limits the amount of source replication
data it sends to not exceed a specified maximum bandwidth. Schedule replication throttling
to control the amount of network bandwidth used by source replication at certain times. For
example, you might configure replication throttling to occur during planned backup times to
avoid network contention.
I
To schedule replication throttling:
1. On the Scheduler page, add or edit an event in the Replication Throttle row (see
"Adding or Editing a Scheduled Event" on page
2. Specify the maximum allowed bandwidth by entering a value in the Bandwidth box and
selecting the units in the drop-down box (KB/s or MB/s). The lowest value you can set
is 32 KB/s. The highest value you can set is 125 MB/s.
V
During the replication throttle event, the ETERNUS CS800 will limit the amount of data
it sends during source replication so that it does not exceed the specified bandwidth.
After the replication throttle event ends, the ETERNUS CS800 will no longer throttle the
sending of source replication data (until the next replication throttle event occurs).
The maximum duration for a scheduled replication throttle event is 31 days. If you need
to configure throttling for a longer period, set a constant throttle instead. To set a
constant replication throttle, use the Configuration > Replication page (see
System Throttling" on page
Do not configure a throttle schedule if a constant throttle is enabled. 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.)
3. (Optional) Specify when and how often the event reoccurs (see
a Scheduled Event" on page
4. Click Apply.

For more information about replication, see
CAUTION!
Do not set the maximum allowed bandwidth to a value that is lower than
necessary. If the maximum allowed bandwidth is set to the lowest value, large
replication jobs may fail.
