Fibre Channel QoS Policy

A Fibre Channel QoS Policy controls traffic shaping parameters for vHBA interfaces, including burst size, class of service, maximum FC frame payload size, and rate limiting. Most deployments use the defaults (CoS 3, max data field size 2112).

Examples

Example-1: The example below demonstrates an FC QoS policy using standard defaults suitable for most FC initiator deployments.

compute:
  intersight:
    organizations:
      - name: MyOrganization
        policies:
          fibre_channel_qos:
            - name: fc-qos-default
              description: Standard FC QoS policy
              tags:
                - key: env
                  value: prod

Example-2: The example below demonstrates an FC QoS policy with a rate limit for bandwidth-constrained environments.

compute:
  intersight:
    organizations:
      - name: MyOrganization
        policies:
          fibre_channel_qos:
            - name: fc-qos-limited
              description: Rate-limited FC QoS policy
              burst: 10240
              cos: 3
              max_data_field_size: 2112
              rate_limit: 4000
