Set FC Host QoS

Overview

This function configures the bandwidth limit (the maximum performance limit) of the FC host.

Caution
  • This function can be used, irrespective of whether the QoS mode has been enabled or disabled. However, if the QoS mode has been disabled, the host starts the operation within the configured bandwidth limit only when the QoS mode is enabled.

Note
  • Configure the port bandwidth limit on each port. Refer to the [Set FC Port QoS] function, the [Set iSCSI Port QoS] function, or the [Set SAS Port QoS] function for details.

  • The host LUN bandwidth limit can be configured in the LU QoS group. Refer to the [Set Host-LU QoS] function for details.
