4.7.11 Set iSCSI Port QoS
This function specifies the bandwidth limit (maximum performance limit) for the iSCSI port.
For details on the parameters for this function, refer to "A.4.6.6 Set iSCSI Port QoS" (page 881)
.
For the factory default settings for this function, refer to "Appendix B Set iSCSI Port QoS" (page 1001)
.
The procedure to set the iSCSI port QoS is as follows:
1 Select the iSCSI port to set the bandwidth limit (multiple selections can be made), and click
[Set iSCSI Port QoS] in [Action].
2 Select the iSCSI port bandwidth limit.
• 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", the bandwidth limit cannot be specified.
• If the port mode has been changed from "CA" or "CA/RA" to "RA", the bandwidth limit returns to the
default value.
• This function can be used, irrespective of whether the QoS mode has been enabled or disabled. If the QoS
mode has been disabled, the port starts the operation within the configured bandwidth limit after the
QoS mode is enabled.
• Configure the host bandwidth limit on each host. Refer to the following sections for details:
- "4.7.7 Set FC/FCoE Host QoS" (page 489)
- "4.7.8 Set iSCSI Host QoS" (page 490)
- "4.7.9 Set SAS Host QoS" (page 492)
• The LUN bandwidth limit can be configured in the LU QoS group. Refer to "4.7.3 Set Host-LU QoS" (page
482) for details.
