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.
For more information about configuring the ETERNUS CS800 for replication, see
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 288
).
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 for 1GbE and 500 MB/s for 10GbE.
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.
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).
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

About Replication Throttling Statistics
Keep in mind the following information when observing actual network bandwidth usage
during a replication throttle event:
l
During a replication throttle event, only outgoing replication data traffic is throttled, not
other outgoing traffic. Because of this, you may observe network usage to be higher than
the specified maximum bandwidth. Differences in the sampling time period may also
