Send Settings Information
Original Data Size
Actual Data Sent
Average Send Rate
Additional Information
Average Data Sent is based on actual bytes sent over network, the average send rate could be low if
l
differential between the replications is low
The Average Send Rate can be low if a replication target is un-configured and configured again. The
l
replication send statistics for a particular target are reset when it is un-configured. Only new
replications to the target will be considered when calculating average replication rate.
OST network traffic may or may not be considered when calculating actual data statistics. It is
l
considered only if the storage server has the following configuration:
Concurrent optimized duplication enabled.
o
Unique data gets replicated through concurrent optimized replication and not through an actual
o
optimized duplication operation.
The replication metadata transferred over network is not considered in calculating Average Send
l
Rate statistics.
Receive Settings & Cumulative Statistics
The Receive Settings & Cumulative Statistics section displays statistics for all data received by the
system from all sources since system installation or since Receive cumulative replication statistics were last
cleared by clicking Clear Receive on the Replication Actions page (see
page 160).

Description
The original, native size of data sent during replication or failback. This
value does not represent the amount of data actually sent over the
network during replication or failback because data is deduplicated and
compressed before being sent.
The amount of data actually sent over the network during replication or
failback. This value is usually much less than the Original Data Size due
to the benefits of data deduplication and compression.
The average send rate (in MB/s) of data sent over the network during
replication or failback (actual size of data sent over the network divided by
the amount of time required to complete replication or failback)
Description
The number of source systems configured to replicate data to the
DXi4700. Click to specify replication sources (see
Configuration on page 253).
