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-4 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-4 adapters family supports
up to 100 Gb/s. To reach 100 Gb/s speed in your network with ConnectX-4
adapters, you must use Mellanox Ethernet / Infiniband switches
supporting 100 Gb (e.g. SN2700 (ETH), SB7700 (IB)). The switch ports
should be configured specifically to use 100 Gb speed. No additional
configuration is required on the adapter side.
Limitations
1. when using iSER and bonding, the storage
interface will be a virtual function under the first port, and will not
support failover.
2. when using SR-IOV and bonding, the virtual functions will be created and allocated from the first interface, and failover is not supported.
