HP XP P9000 for Compatible High Perf FICON Connectivity Software - Manual (Page 54)

For details on the system configuration of one-to-one connections between host bus adapters and
ports, see
“If one-to-one connections link HBAs and ports” (page 47) . This topic explains operation
procedures you can perform for ports and the entire storage system.
Analyzing traffic statistics
The traffic statistics reveal the number of I/Os that have been made via ports. The traffic statistics
also reveal the amount of data that have been transferred via ports. You must analyze the traffic
statistics to determine upper limit values that should be applied to I/O rates or transfer rates for
non-prioritized ports.
The following is the procedure for using the Performance Control main window to analyze traffic
statistics. You can also use the Performance Monitor window to analyze traffic statistics. Performance
Monitor can display a line graph that indicates changes in traffic.
1.
Click Reports > Performance Monitor> Performance Control to open the Performance Control
window.
2. Click to change to Modify mode.
3. In the Performance Control window, click Performance Control. The Performance Control main
window appears.
4. Select the Port 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 of the list.
•
To analyze transfer rates, select MB/s from the list at the upper left corner of the list.
The list displays traffic statistics (i.e., the average and peak I/O rates or transfer rates)
of the ports.
7. Analyze the information in the list and then determine upper limit values that should be applied
to non-prioritized ports. If necessary, determine threshold values that should be applied to
prioritized ports. For details on the upper limit values and threshold values, see
“If one-to-one
connections link HBAs and ports” (page 47) .
Setting priority for ports on the storage system
If one-to-one connection is established between HBAs and ports, you need to measure traffic
between high-priority HBAs and prioritized ports. You also need to measure traffic between
low-priority HBAs and non-prioritized ports.
Prioritized ports are ports on which the processing has high priority and non-prioritized ports are
ports on which the processing has low priority. Specify a port that connects to a high-priority host
bus adapter as a prioritized port. Specify a port that connects to a low-priority host bus adapter
as a non-prioritized port.
1.
Click Reports >Performance Monitor> Performance Control to open the Performance Control
window.
2. Click to change to Modify mode.
3. In the Performance Control window, click Performance Control. The Performance Control main
window appears.
4. Ensure that the Port tab is displayed.
5. Select All from the list at the top right corner of the window.
6. Right-click a high-priority port and then select Non-Prio ->> Prio from the pop-up menu. If there
is more than one high-priority port, repeat this operation. The Attribute column displays Prio.
