OpenStack integration requires the Modular Layer 2 (ML2) Mechanism Driver to interact with Extreme Fabric Automation (EFA). The Neutron drivers and plugins communicate with EFA over the REST interface.
The EFA plugin for OpenStack is packaged as RPM files.
The EFA OpenStack plugin package supports many features. For details, see OpenStack Ecosystem Integration Management.
System requirements for EFA are provided in the Extreme Fabric Automation Deployment Guide.
