About the SRDF report
The SRDF report presents information regarding optimized throughput and data reduction for EMC's Symmetrix Remote Data Facility (SRDF) protocol. The report measures only LAN-side traffic on an encoding appliance. You can view a summary of performance statistics for all optimized SRDF traffic, as well as drill into metrics for a specific EMC Symmetrix array or an individual remote data facility (RDF) group within an array.
You can also check the total optimized SRDF traffic throughput by viewing the Reports > Optimization: Optimized Throughput report.
The SRDF report contains this information:
Data Reduction
Displays the percentage of total decrease in overall data transmitted (when viewing all Symmetrix RDF groups).
WAN/LAN Throughput
Displays the total throughput transmitted over the WAN and LAN.
When the report display includes all Symmetrix RDF group or a single RDF group for a single Symmetrix ID, the navigator shadows the LAN/WAN throughput series. When the report display includes all RDF groups for a single Symmetrix ID, navigator shadows the group 1 LAN/WAN throughput series.
The SRDF report answers these questions:
• How much total SRDF traffic is processing over time?
• How much data reduction is being delivered overall?
• How much data reduction is being delivered for individual RDF groups?
• that Symmetrix array is generating the most SRDF traffic?
• How are SRDF traffic patterns changing over time?
Mouse over a specific data point to see what the y values and exact time stamp were in relation to peaks.
The Riverbed system reports for periods up to one month. Due to performance and disk space considerations, data representation in reports for periods longer than the last five minutes are interpolated between data points obtained by aggregating more than one 10-second sample. The display granularity decreases with time passed since data was sampled.
