HP XP7 Storage - Manual (Page 55)

When you set an upper limit for the first time, it is recommended that the upper limit value be
approximately 90 percent of the peak traffic.
Prerequisites
•
Required role: Storage Administrator (System Resource Management)
•
You must enable the Remote Web Console secondary window. For details, see the HP XP7
Remote Web Console User Guide.
1. Display the Remote Web Console main window.
2. Click Reports > Performance Monitor > Performance Control to open the Performance Control
window.
3. Click to change to Modify mode.
4. In the Performance Control window, click Performance Control. The Performance Control main
window appears.
5. Select the Port tab.
6. Do one of the following:
•
To limit the I/O rate for the non-prioritized port, select IOPS from the list at the upper left
corner of the list.
•
To limit the transfer rate for the non-prioritized port, select MB/s from the list at the upper
left corner of the list.
7. Locate the non-prioritized port in the list.
NOTE: The Attribute column of the list indicates whether ports are prioritized or non
prioritized. If you cannot find any non prioritized port in the list, check the list at the top right
corner of the window. If the list displays Prioritize, select All or Non Prioritize from the list.
8. Do one of the following:
•
To limit the I/O rate for the non-prioritized port, double-click the desired cell in the IOPS
column in Upper, and enter the upper limit value in the cell.
•
To limit the transfer rate for the non-prioritized port, double-click the desired cell in the
MB/s column in Upper, and enter the upper limit value in the cell.
In the list, either of IOPS or MB/s column is activated depending on the rate selected in
step 3 above. You can use either of them to specify the upper limit value for one port.
You can specify different types of rates (IOPS or MB/s) for the upper limit values of different
non-prioritized ports.
The upper limit value that you entered is displayed in blue.
CAUTION: If an upper limit of the non-prioritized WWN is set to zero or nearly zero,
I/O performance might be lowered. If I/O performance is lowered, the host cannot be
connected to the storage system in some cases.
9. Click Apply to apply the settings to the storage system. The upper limit value that you entered
turns black.
