In the Performance Control window, click Performance Control. The Performance Control main
window appears.
4.
Select the WWN tab.
5.
Select All from the list at the top right corner of the window.
6.
Do one of the following:
•
To analyze I/O rates, select IOPS from the list at the upper left corner.
•
To analyze transfer rates, select MB/s from the list at the upper left corner of the list.
7.
Below the Storage System folder in the upper-left tree, click the icon of the port whose traffic
statistics you want to collect.
The list displays traffic statistics (I/O rates or transfer rates) about the host bus adapters that
connect to the selected port.
The following two types of traffic are shown. The traffic has attributes including the average
and maximum values.
•
Traffic between the host bus adapter and the selected port (shown in Per Port)
•
Sum of the traffic between the host bus adapter and all the ports connected to the host
bus adapter (shown in WWN Total)
NOTE:
The traffic statistics only about the host bus adapters below Monitor appear in
the list.
The WWN Total traffic statistics will also be displayed in the list when you click an icon
in the lower left tree. If you click the Storage System folder in the lower left tree, the sum
of the traffic of the host bus adapters registered on each PFC group is displayed. For
details on PFC groups, see
“Grouping host bus adapters” (page 65)
.
8.
Analyze the information in the list and then determine upper limit values that should be applied
to non-prioritized WWNs. If necessary, determine threshold values that should be applied to
prioritized WWNs. For details, see
“If many-to-many connections link HBAs and ports”
Setting priority for host bus adapters
If many-to-many connection is established between host bus adapters (HBAs) and ports, you need
to define the priority of WWNs, measure traffic between each HBA and the port that the HBA is
connected to, and analyze the traffics.
The host bus adapters (HBAs) are divided into two types: Prioritized WWNs and non-prioritized
WWNs. Prioritized WWNs are the host bus adapters that are used for the high-priority processing,
and non-prioritized WWNs are the host bus adapters that are used for the low-priority processing.
Specify a host bus adapter existed in a server, on which the high-priority processing is performed,
as a prioritized WWNs. Specify a host bus adapter existed in a server, on which the low-priority
processing is performed, as a non-prioritized WWNs.
