Setting Upper-Limit Values For Non-Prioritized Ports: One-To-One Connections - HPE XP7 User Manual

Setting upper-limit values for non-prioritized ports: one-to-one connections

After you analyze traffic statistics, you can set upper limit values for I/O rates or data transfer
rates on non-prioritized ports to provide better performance for high-priority host servers. For
details about upper limit values, see
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 XP7
Remote Web Console User Guide.
Procedure
1. Open the Performance Control window.
In Command View Advanced Edition:

2. Click
3. In the Performance Control window, click Performance Control. The Performance Control
main window appears.
4. Select the Port tab.
5. Select whether to limit the I/O rate or the transfer rate for the non-prioritized port:
To limit the I/O rate, select IOPS from the list at the upper left corner of the list.
To limit the transfer rate, select MB/s from the list at the upper left corner of the list.
6. Locate the non-prioritized port in the list.
NOTE:
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.
7. Enter the desired upper limit value for the non-prioritized port:
To set the upper limit for the I/O rate, double-click the desired cell in the IOPS column
in Upper, and enter the upper limit value in the cell.
To set the upper limit for the transfer rate, 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 the IOPS or MB/s column is activated depending on the selected rate.
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.
to change to Modify mode.
The Attribute column of the list indicates whether ports are prioritized or non
