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.

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	Specifies the total decrease of data transmitted over the WAN, according to the following
Last Week	calculation:
	(Data In – Data Out)/(Data In)
Peak Data Reduction % over	Specifies the peak decrease in data transmitted over the WAN.
Last Week
Peak Data Reduction Occurred	Specifies the time that the peak data reduction occurred.
At
Capacity Increase	Specifies the increase in the amount of data transmitted over the WAN, according to the
	following calculation:
	1/(1-Reduction Rate)

What this Report Tells You

About Report Graphs

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?

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.
