• Threshold: In the Port tab, specifies the threshold for I/O and transfer rates for each prioritized port.
Use the IOPS column to specify the threshold for I/O rates. Use the MB/s column to specify the
threshold for transfer rates. To specify a threshold, double-click a cell to display the cursor in the
cell.
• Upper: Specifies the upper limit on I/O and transfer rates for each non-prioritized port or WWN.
Use the IOPS column to specify the upper limit for I/O rates. Use the MB/s column (or 100KB/s
column for WWN) to specify the upper limit for transfer rates. To specify an upper limit,
double-click a cell to display the cursor in the cell.
NOTE:
The Upper columns are not displayed in the WWN tab if a PFC group is selected in the
lower-left tree view.

•
If you click the All Thresholds check box and enter a threshold value in the text box, the threshold value
is applied to the entire disk array. To specify the threshold for I/O rates, select IOPS from the list on the
right of the text box. To specify the threshold for transfer rates, select MB/s (or 100KB/s in the WWN
tab) from the list. For example, if you specify 128 IOPS in All Thresholds, the upper limits on
non-prioritized ports are disabled when the sum of I/O rates for all the prioritized ports is below 128
IOPS.
•
The Delete ports if CHA is removed check box deletes settings on ports in channel adapters that have
been removed.
Buttons
•
Apply: Applies settings in this pane to the disk array.
•
Reset: Restores original settings in the pane.
•
Initialize: Changes settings in this pane as explained below, and applies the resulting settings to the
disk array:
• All ports or WWNs become prioritized ports or WWNs.
• The threshold value for all ports in the Port tab becomes 0 (zero).
NOTE:
The pane displays a hyphen (-) instead of 0 (zero).
• If you check the All Thresholds check box, the check mark disappears.
•
Close: Closes the Performance Control pane.
Managing traffic between HBAs and ports
If one-to-one connections are established between host bus adapters (HBAs) and disk array ports, use the
Port tab in the Performance Control pane to measure and analyze traffic.
If many-to-many connections are established between host bus adapters (HBAs) and disk array ports, use
the WWN tab in the Performance Control pane to measure and analyze traffic.
Use the Port and WWN tabs to perform the following functions:
•
Setting the priority of ports on disk arrays
•
Measuring traffic between host bus adapters and ports for many-to-many connections
•
•
Setting upper limit values for traffic at non-prioritized ports or WWNs
•
•
Changing PFC names of host bus adapters (many-to-many connections only)
•
