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 page (see Replication Performance on
page 167).
ReceiveSettingsInformation Description
SourceDXis The number of source systems configured to replicate data to the
DXi6900. Click to specify replication sources (see Replication
Configuration on page 268).
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).
