| |
| − | OpenStack Juno added inbox support to request VM access to virtual network via SR-IOV NIC. With the introduction of SR-IOV based NICs, the traditional virtual bridge is no longer required. Each SR-IOV port is associated with a virtual function (VF). SR-IOV ports may be provided by Hardware-based Virtual Ethernet Bridging (HW VEB); or they may be extended to an upstream physical switch (IEEE 802.1br).
| |
| − | There are two ways that SR-IOV port may be connected:
| |
| − | * directly connected to its VF
| |
| − | * connected with a macvtap device that resides on the host, which is then connected to the corresponding VF
| |

| |
| − | * '''Clean Red Hat 7.2'''
| |
| − | * All nodes equipped with Mellanox ConnectX®-3/Pro/4 Network Adapter [http://www.mellanox.com/page/products_dyn?product_family=119]
| |
| − | * FW for Connect®-4 12.14.0050 and newer.
| |
| − | * Mellanox OFED 3.2-0.0.4.0 or greater installed on all nodes. Please refer to Mellanox website for the latest OFED: [http://www.mellanox.com/page/products_dyn?product_family=26&mtag=linux_sw_drivers]
| |
| − | * SR-IOV enabled on all compute nodes. For more information, please refer to Mellanox Community click [https://community.mellanox.com/docs/DOC-1317].

Configuration
[SR-IOV]
SDN Mechanism Driver
SDN Mechanism Driver allows NEO to configure dynamically VLANs on the Mellanox Switches.
Further Reading
Ceilometer
The Mellanox Ceilometer SR-IOV module allows the OpenStack Ceilometer to collect measurements of SR-IOV counters.
More details about applying Mellanox Ceilometer module can be found here
