Setting a threshold for the entire storage system: many-to-many connections

If threshold control is used, upper limit control is automatically disabled when traffic between
production servers and the storage system is reduced to a specified level. For details, see
"Upper-limit control" (page 105)
(page 119).
If many-to-many connections are established between host bus adapters and storage system
ports, you can set one threshold value for the entire storage system. In this environment, you
cannot set individual threshold values for each prioritized WWN.
Prerequisites
Required role: Storage Administrator (System Resource Management)
You must enable the Remote Web Console secondary window. For details, see the XP7
Remote Web Console User Guide.
Procedure

3. In the Performance Control window, click Performance Control. The Performance Control
main window appears.
4. Select the WWN tab.
5. Select the All Thresholds check box.
6. Select IOPS or MB/s from the All Thresholds list, and do one of the following:
To specify the threshold value by using the I/O rate, select IOPS from the list below the
check box.
To specify the threshold value by using the transfer rate, select MB/s from the list below
the check box.
Even if the types of rates differ between the upper limit values and the threshold value,
the threshold control is effective for all non-prioritized WWNs.
7. Enter the threshold in the text box of All Thresholds.
CAUTION:
hyphen (-) and the threshold for the prioritized port becomes ineffective. If the thresholds
of all prioritized ports are ineffective, threshold control will not be performed but upper limit
control will be performed.
