!!! note "Environment Assumptions"
This document assumes you are running at least 2 ProxmoxVE nodes. For the sake of the example, it will assume they are named `proxmox-node-01` and `proxmox-node-02`. We will also assume you are using TrueNAS Core. TrueNAS SCALE (should work) in the same way, but there may be minor operational / setup differences between the two different deployments of TrueNAS.
Secondly, this guide assumes the ProxmoxVE cluster nodes and TrueNAS server exist on the same network `192.168.101.0/24`.
## All ProxmoxVE Cluster Nodes
### Configure SSH Key Exchange
The first step is creating SSH trust between the ProxmoxVE cluster nodes and the TrueNAS storage appliance. You will leverage the ProxmoxVE `shell` to run the following commands.

## Primary ProxmoxVE Cluster Node
From this point, we are ready to add the shared storage provider to the cluster via the primary node in the cluster. This is not strictly required, just simplifies the documentation.
