Mellanox plugin
The Mellanox Fuel plugin is a bundle of scripts,
packages and metadata that will extend Fuel and add Mellanox features
such as SR-IOV for networking and iSER protocol for storage.
Fuel can configure Mellanox
ConnectX-3 Pro network adapters to accelerate the performance of
compute and storage traffic.
This implements the following performance enhancements:
- Compute nodes network enhancements:
-
- SR-IOV based networking
- QoS for VM traffic
- VXLAN traffic offload
- Cinder nodes use iSER block storage as the iSCSI transport rather than the default iSCSI over TCP.
These features reduce CPU overhead, boost
throughput, reduce latency, and enable network traffic to bypass the
software switch layer (e.g. Open vSwitch).
Mellanox Plugin integration with Mellanox NEO
SDN Controller enables switch VLAN auto provisioning and port
configuration for Ethernet and SM PK auto provisioning for InfiniBand
networks, over private VLAN networks.

The Mellanox ConnectX-3 Pro adapters family
supports up to 40/56 Gb. To reach 56 Gb speed in your network with
ConnectX-3 Pro adapters, you must use Mellanox Ethernet / Infiniband
switches supporting 56 Gb (e.g. SX1710, SX6710). The switch ports should
be configured specifically to use 56 Gb speed. No additional
configuration is required on the adapter side. For additional
information about how to run in 56GbE speed, see HowTo Configure 56GbE
Link on Mellanox Adapters and Switches.
Limitations
- Mellanox SR-IOV is supported only when choosing Neutron with VLAN segmentation.
- ConnectX-3 Pro adapters are required in order to enable VXLAN HW offload over Ethernet networks.
- QoS feature is implemented only for Ethernet VLAN SR-IOV ports using ConnectX-3 Pro adapters.
- Infiniband is configured by using OpenSM only.
