Reports
The Performance - Bandwidth Optimization report summarizes the overall inbound
and outbound bandwidth improvements for your network using the HP EFS WAN
Accelerator. You can create reports according to the time period of your choice,
application, and type of traffic.
The Performance - Bandwidth Optimization report includes the following table of
statistics that describe bandwidth activity for the time period you specify.
What this Report
Tells You
The Performance - Bandwidth Optimization report answers the following questions:
 How much bandwidth optimization has occurred?
 What was the average and peak amount of data sent?
 What was the rate at which data was sent?
 What was the overall increase in the amount of data that can be transmitted using
the HP EFS WAN Accelerator?
About Report
Graphs
In bar-graph and line-graph reports, the x-axis (or tick mark) plots time, according to
the interval you select. The y-axis plots the metric of interest, such as gigabytes (GB)
of bandwidth, percent (%) of data reduction, connection counts, and the like.
A diamond icon above the top margin of the graph points to the value on the x-axis (the
time) at which the peak occurred.
A diamond icon outside the right margin of the graph points to the value on the y-axis
(for example, the percent) that is the average value for the time period selected.
Pie chart graphs do not indicate peaks or averages. Pie chart graphs represent the
aggregate for the time period selected.
Field Description
WAN Data Specifies the bytes sent over the Wide Area Network (WAN) using the HP EFS WAN
Accelerator.
LAN Data Specifies the bytes sent over the Local Area Network (LAN) using the HP EFS WAN
Accelerator.
Total Data Reduction % over
Last Week
Specifies the total decrease of data transmitted over the WAN, according to the following
calculation:
(Data In – Data Out)/(Data In)
Peak Data Reduction % over
Last Week
Specifies the peak decrease in data transmitted over the WAN.
Peak Data Reduction Occurred
At
Specifies the time that the peak data reduction occurred.
Capacity Increase Specifies the increase in the amount of data transmitted over the WAN, according to the
following calculation:
1/(1-Reduction Rate)
