3.
In the Performance Control window, click Performance Control. The Performance Control main
window appears.
4.
Ensure that the WWN tab is displayed.
5.
Do one of the following:
•
To limit the I/O rate of the non-prioritized WWN, select IOPS from the list at the upper
left corner.
•
To limit the transfer rate of the non-prioritized WWN, select MB/s from the list at the
upper left corner.
6.
In the upper-left tree, click the icon of the port whose traffic you want to limit below the Storage
System folder.
The information about the host bus adapters which connect to the selected port is displayed
in the list.
7.
Locate the non-prioritized WWN in the list.
NOTE:
•
The Attribute column of the list indicates whether WWNs are prioritized or non-prioritized.
The Attribute column of a non-prioritized WWN displays Non-Prio.
•
If you cannot find any non-prioritized WWN in the list, check the list at the top right
corner of the window. If the list displays Prioritize, select All or Non-Prioritize.
8.
Do one of the following:
•
To limit the I/O rate of the non-prioritized WWN, double-click the desired cell in the IOPS
column in Upper. Next, enter the upper limit value in the cell.
•
To limit the transfer rate of the non-prioritized WWN, double-click the desired cell in the
MB/s column in Upper. Next, enter the upper limit value in the cell.
In the list, either of the IOPS cells or MB/s cells are activated depending on the rate you
specified in step 5. You can specify the limit value by using either of the I/O rate or
transfer rate for each host bus adapter. The upper limit value that you entered is displayed
in blue. It is allowed that you specify upper limit values by using the I/O rate for some
host bus adapters and specify them by using the transfer rate for the other host bus
adapters.
NOTE:
◦
You cannot specify or change the upper limit value of a host bus adapter which is
contained in an PFC group. The upper limit value of such a host bus adapter is
defined by the PFC group settings. For details on how to specify an upper limit value
for an PFC group, see
“Setting an upper-limit value to HBAs in an PFC group”
.
◦
If one host bus adapter is connected to multiple ports and you specify an upper limit
value of the host bus adapter for one port, the specified upper limit value will be
applied to the host bus adapter settings for other connected ports automatically.
9.
Click Apply.
The settings in the window are applied to the storage system. The upper limit value that you
entered turns black.
Setting a threshold
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
and
“If many-to-many connections link HBAs and ports” (page 49)
