Description Item
Change the type of performance statistic to display in the WWN list.
• The list at the upper left corner of the list enables you to change the type of performance
statistics to be displayed in the list.
• If IOPS (I/Os per second) is selected, the list displays I/O rates for ports.
• If MB/s (megabytes per second) is selected, the list displays the transfer rates for ports.
Statistic
type
A list of WWNs and the I/O rate or the transfer rate for each host bus adapter corresponding
to the selection in the upper-left tree or lower-left tree. Use this list to specify the HBA attributes
and the upper-limit of the HBA traffic.
The measurement unit for the values in the list can be specified by the choice at the upper left
corner of the list. The displayed items will change depending on the selected tree and item. The
HBA traffic (I/O rate and transfer rate) is monitored by Performance Monitor. To specify the
monitoring period, use the Monitoring Term area of Performance Monitor.
On the right side of the list appears the total number of WWNs, the number of prioritized WWNs,
and the number of non-prioritized WWNs.
The list contains the following columns (scroll to view all):
• The WWN column indicates WWNs of HBAs. This column does not appear when you select
the Subsystem folder in the lower-left tree.
• The Performance Control Name column indicates the Performance Control names of HBAs.
XP Performance Control allows you assign a Performance Control name to each HBA so that
you can easily identify each HBA in the Performance Control tabs. This column does not appear
when you select the Subsystem folder in the lower-left tree.
• The Group column indicates the Performance Control group to which the HBA belongs. This
column appears when a port is selected in the upper-left tree and does not appear when a
Performance Control group is selected in the lower-left tree.
• The Per Port column indicates the traffic (I/O rate or transfer rate) between the HBA and the
port selected in the upper-left tree. This item is displayed only when you select an icon in the
upper-left tree. The Per Port column contains the following columns:
Ave.: Indicates the average I/O rate or the average transfer rate for the specified period.
Max.: Indicates the maximum I/O rate or the maximum transfer rate for the specified period.
• The WWN Total column indicates the sum of the traffic (I/O rate or transfer rate) between
the HBA and all the ports connected to the HBA. This value indicates the total traffic of that
HBA. This item is displayed only when you select an icon in the upper-left tree. Whichever
port you select in the tree, the WWN Total column shows the sum of the traffic to all the ports.
The WWN Port column contains the following columns:
Ave.: Indicates the average I/O rate or the average transfer rate for the specified period.
Max.: Indicates the maximum I/O rate or the maximum transfer rate for the specified period.
