• Use the WWN tab to set the limit on performance of non-prioritized WWNs and set the threshold on
performance of prioritized WWNs.

Pane contents
The Port and WWN tabs contain several sections:
Top section
• Current Control Status at the top of the pane displays one of the following values:
• Port Control: System performance is controlled by the upper limits and threshold specified in the Port
tab
• WWN Control: System performance is controlled by the upper limits and threshold specified in the
WWN tab
• No Control: System performance is not controlled by Performance Control XP
If WWN Control appears when the Port tab is active, click Apply to switch control so that Port Control
appears. Conversely, if Port Control appears when the WWN tab is active, click Apply to switch control
so that WWN Control appears.
• Use Control List near the upper right corner of the tab to limit the number of ports or WWNs shown in
the table:
• All: Shows all the ports or WWNs
• Prio.: Shows only prioritized ports or WWNs
• Non-Prio.: Shows only non-prioritized ports or WWNs
If you change a port’s settings, the port remains in the table regardless of the selection in the list.
Tree section (WWN tab only)
• The tree in the upper-left of the WWN tab lists ports and host bus adaptors connected to the array’s
ports.
• Icons representing ports on the array appear below the Subsystem folder.
