Send Settings Information
Description
Actual Data 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.
Average Send Rate
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)
Additional Information
l
Average Data Sent
is based on actual bytes sent over network, the average send rate could be low if
differential between the replications is low
l
The
Average Send Rate
can be low if a replication target is un-configured and configured again. The
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.
l
OST network traffic may or may not be considered when calculating actual data statistics. It is
considered only if the storage server has the following configuration:
o
Concurrent optimized duplication enabled.
o
Unique data gets replicated through concurrent optimized replication and not through an actual
optimized duplication operation.
l
The replication metadata transferred over network is not considered in calculating
Average Send
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
).
Receive Settings Information
Description
Source DXis
The number of source systems configured to replicate data to the
DXi6900. Click to specify replication sources (see
).
Actual Data Received
The amount of data actually received over the network during replication
or failback.
Average Receive Rate
The average receive rate (in MB/s) of data received 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).
