Quantum DXi8500 User’s Guide
During the replication throttle event, the DXi 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 DXi will no longer throttle the sending of source replication data
(until the next replication throttle event occurs).
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.
Note:
To set a constant replication throttle, use the
Configuration > Replication > Send
page (see
Replication Send
on page 309). 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
.)

(Optional) Specify when and how often the event reoccurs (see
Setting Recurrence for a Scheduled Event
on page 363).

About Replication Throttling Statistics
Keep in mind the following information when observing actual network
bandwidth usage during a replication throttle event:
• 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 cause discrepancies between the specified maximum
bandwidth and observed traffic.
• If the DXi is configured to use a bonded network interface for
replication traffic, load balancing is determined independently by
the bonding mode selected for the interface (see
Network
on
page 366). Because of this, you may need to sum the values for all
slave devices in the bonded interface to calculate the overall
outgoing traffic rate.
