# Setting up Zerto multi-site replication on OVHcloud Managed vSphere

## Objective

The purpose of this guide is to provide step-by-step instructions to connect multiple on-premises Zerto deployments to a Managed vSphere instance. By following this guide, users will be able to establish secure multi-site replication, ensure disaster recovery readiness, and manage data protection across different sites.

**Find out how to set up Zerto Virtual Replication between your Hosted Private Cloud platforms.**


***

### OVHcloud Control Panel Access

- **Direct link:** [VMware vSphere](https://manager.eu.ovhcloud.com/#/dedicated/dedicated_cloud)
- **Navigation path:** <code className="action">Hosted Private Cloud</code> > <code className="action">Managed VMware vSphere</code> > Select your vSphere service

***


## Requirements

- **Managed vSphere Setup**: A Managed vSphere environment with Zerto already deployed.
- **On-Premises Zerto**: Zerto is installed and configured on your local infrastructure.
- **VPN Information**: All necessary VPN credentials, IP addresses, and keys for both on-premises and Managed vSphere environments.

:::info
Appropriate administrative access to Zerto Manager on both Managed vSphere and on-premises sites.
:::

## Instructions

### 1 - Access Zerto Manager on Managed vSphere

- Log in to the <ManagerLink to="/">OVHcloud Control Panel</ManagerLink>, then go to the `Hosted Private Cloud` section.
- Click the `Managed VMware vSphere` menu and select the infrastructure concerned.
- Navigate to the `Datacenters` tab and select the datacenter.
- Navigate to the `Zerto` tab.

### 2 - Add your On-Premises Zerto Site

Click the `Add a site` button, enter your VPN information (IP address and encryption key), and enter the details of your on-premises Zerto deployment. Refer to our example screenshot for guidance:

### 3 - Start VPN Configuration

Submit your information. The Managed vSphere will automatically start the VPN setup, allowing secure access to your on-premises Zerto site.

### 4 - Let Automated Processes Run

Managed vSphere will run automated tasks to configure multi-site connectivity.

Wait until the status shows `Configuration deployed`.

### 5 - Connect the VPN

Connect your on-premises VPN to the Managed vSphere's Zerto VPN and verify that the connection is active.

### 6 - Pair the Zerto Sites

- On Managed vSphere Zerto, go to `Sites` tab and get the token:

- On your on-premises Zerto, choose `Pair to a site` and enter the Managed vSphere Zerto IP and token:

Once paired, your multi-site replication setup is complete.

## Network Diagram

The following diagram illustrates the connectivity setup for multi-site Zerto replication between the customer site and Managed vSphere:

![network diagram](/images/guides/hosted-private-cloud/powered-by-vmware/zerto-multi-site/network_diagram.png)

Diagram Explanation:

- **OPNSense Public IP**: The public IP of the customer firewall/router.
- **OPNSense Private IP**: The internal IP address of the customer firewall.
- **ZVM Private IP**: The internal IP of the customer Zerto Virtual Manager.
- **Internal ZVM Network**: The LAN connecting customer ZVM and vRAs.
- **OVHcloud Public IP**: The public-facing IP for the Managed vSphere.
- **OVHcloud ZVM Network /23**: The private network within the hosted Managed vSphere.
- **ZVM Private IP (Managed vSphere)**: The private IP addresses of Zerto VMs (ZVM and vRAs) hosted in Managed vSphere.

This setup ensures secure VPN connectivity between on-premises Zerto and OVHcloud Managed vSphere, allowing multi-site replication and disaster recovery.

## Troubleshooting Tips

- **VPN issues**: Check credentials, firewall and network settings.
- **Token/site pairing**: Verify the token, ZVM IP and Zerto license.

## Security Considerations

- Use strong encryption for all VPN connections.
- Ensure secure authentication methods are in place.
- Limit access to Zerto and Managed vSphere management interfaces.
- Regularly review logs and monitor for suspicious activity.
- Keep Zerto and Managed vSphere software up to date with security patches.
