Why each option
To control only vHBA traffic with a QoS policy in Cisco UCS, the Fibre Channel policy must be used.
The 'Best Effort' QoS policy provides no guarantees and is unsuitable for critical FCoE traffic which requires lossless delivery.
The 'Fibre Channel' QoS policy in Cisco UCS is specifically designed to handle Fibre Channel over Ethernet (FCoE) traffic originating from virtual Host Bus Adapters (vHBAs). This policy ensures that FCoE traffic receives the necessary lossless treatment and prioritization for reliable storage connectivity.
