8. Right-click a lower-priority port and in the pop-up menu select Prio ->> Non-Prio. The Attribute
column displays Non-Prio. Repeat this action for each lower-priority port. You can set upper
limit values only on the Non-prio. ports.
9. Click Apply to apply the settings to the storage system.
Now that you have set the port priorities, you can start monitoring the traffic (I/O rates and
transfer rates) to collect data for analysis.

Analyzing traffic statistics: one-to-one connections
You must analyze the traffic statistics to determine the upper limit values that should be applied to
I/O rates or transfer rates on non-prioritized ports.
Prerequisites
•
Required role: Storage Administrator (System Resource Management)
•
You must enable the Remote Web Console secondary window. For details, see the HP XP7
Remote Web Console User Guide.
1. Display the Remote Web Console main window.
2. Click Reports > Performance Monitor > Performance Control to open the Performance Control
window.
3. Click to change to Modify mode.
4. In the Performance Control window, click Performance Control. The Performance Control main
window appears.
5. Select the Port tab.
6. Select All from the list at the top right corner of the window.
7. Display the desired traffic statistics as follows:
•
To view I/O rates, select IOPS from the list at the upper left corner of the list.
•
To view transfer rates, select MB/s from the list at the upper left corner of the list.
The list displays the traffic statistics (average and peak I/O rates or transfer rates) of the ports.
8. Analyze the data in the list to determine the upper limit values that should be applied to
non-prioritized ports and, if desired, the threshold values that should be applied to prioritized
ports or the storage system.
9. To view the traffic statistics on data graphs, see “Displaying the monitor data on graphs”
(page 21) .
To export the traffic statistics (as text in CSV format) for analysis in other applications, see
“Using the Export Tool” (page 92) .

Setting upper-limit values for non-prioritized ports: one-to-one connections
After you analyze traffic statistics, you can set upper limit values for I/O rates or data transfer rates
on non-prioritized ports to provide better performance for high-priority host servers. For details
about upper limit values, see
“Upper-limit control” (page 44) .
