Install EFA in a Single-Node Deployment

You can install EFA in a single-node, non-TPVM deployment.

Verify the following prerequisites:

CPU: 4 cores
Storage: 50 GB
RAM: 8 GB
OS: Ubuntu 16.04 or 18.04

Ensure you have configured NTP according to EFA Requirements.

To install EFA, you must be a root user or have sudoers privileges.

Download the image (*.tar.gz).
Untar the image.
```
$ tar –xzf efa-v2.x.x.tar.gz
```
Verify the PGP signature as described in article 48172 on the Extreme Portal.
The process is also described in the Extreme Fabric Automation Release Notes.
Change to the EFA directory.
```
$ cd efa
```
Run the deployment script.
When prompted, ensure that you select single-node and either secure or standard mode. For more information, see EFA Installation Modes.
