Table 6 Relationship between the thresholds of the prioritized port and the upper limits
of the non-prioritized port
Zero is set to the upper limit of the
non-prioritized port A number other than zero is set to the upper
limit of the non-prioritized port Thresholds settings
The threshold control of the prioritized
port is not executed. When thresholds are set to multiple prioritized
ports, depending on the transfer rate, following
controls are executed. Threshold Is Set to
The Prioritized port
◦
If I/O rate or transfer rate exceeds the
threshold in any prioritized port, upper limits
of all the non-prioritized ports take effect.
◦
If I/O rate or transfer rate goes below the
threshold in any prioritized port, upper limits
of all the non-prioritized ports do not take
effect.
The specified upper limit always takes effect. Threshold Is Not
Set to The
Prioritized port
•
To set one threshold to the entire storage system, select the All Thresholds check box.
Next, select IOPS or MB/s from the list of right side in All Thresholds and enter the threshold
value in the text box. Even if the types of rates for upper limit values and the threshold
are different, the threshold control can work for all the non-prioritized ports.

WWN tab operations
If many-to-many connections are established between host bus adapters (HBAs) and storage system
ports, you use the WWN tab in the Performance Control main window to do the following:
•
Make all the traffics between host bus adapters and ports monitored
•
Analyze traffic statistics
•
Measure traffic between host bus adapters and storage system ports
•
Set priority to host bus adapters
•
Set an upper limit on traffic at non-prioritized WWNs
•
Set a threshold, if necessary
If many-to-many connections are established between host bus adapters and ports, you should
specify the priority of I/O operations on each host bus adapter. You can specify the upper limit
values on the non-prioritized WWNs. If necessary, you can set one threshold value applied for
the entire storage system. When many-to-many connections are established between host bus
adapters and ports, you cannot set individual thresholds for prioritized WWNs.
For the system configuration of many-to-many connections between host bus adapters and ports,
see
“If many-to-many connections link HBAs and ports” (page 49) .
For details on the system configuration of many-to-many connections between host bus adapters
and ports, see
“If many-to-many connections link HBAs and ports” (page 49) . This topic explains
operation procedures you can perform for host bus adapters and the entire storage system.
Monitoring all traffic between HBAs and ports
When many-to-many connections are established between host bus adapters (HBAs) and ports,
you should make sure that all the traffic between HBAs and ports is monitored.
