9.2.7.9 Set FC Port QoS
This function specifies the bandwidth limit (maximum performance limit) for the FC port.
The procedure to set the FC port QoS is as follows:
Procedure
1 Select the FC port to set the bandwidth limit (multiple selections can be made), and click
[Set FC Port QoS] in [Action].
• The bandwidth limit can be configured only for the ports in the port mode of "CA" or "CA/RA". For the ports
in the port mode of "RA" and "Initiator", the bandwidth limit cannot be specified.
• If the port mode has been changed from "CA" or "CA/RA" to "RA" or "Initiator", the bandwidth limit returns
to the default value.
• This function can be used, irrespective of whether the Host-LU QoS is enabled or disabled. However, if the
Host-LU QoS has been disabled, the host starts operating within the configured bandwidth limit after the
Host-LU QoS is enabled.
• Configure the port bandwidth limit on each host. Refer to the following sections for details:
- "9.2.7.6 Set FC/FCoE Host QoS" (page 605)
- "9.2.7.7 Set iSCSI Host QoS" (page 607)
- "9.2.7.8 Set SAS Host QoS" (page 608)
• The LUN bandwidth limit can be configured in the LU QoS group. Refer to "9.2.7.2 Set Host-LU QoS" (page
599) for details.
