In a large-scale virtual environment, setup VMware Auto Deploy can offer significant advantages and allows for flexible deployment models. The prerequisite for realizing this condition is the ability to fluently operate vSphere Auto Deploy. This article from three parts ( before, during, after) to introduce you a smooth way to have VMware Auto Deploy setup.
VMware Auto Deploy is a feature within VMware vSphere which allows you to deploy and configure ESXi hosts over the network, without the need for manual installation. It is typically used in environments with large numbers of hosts. Also you can choose host profiles to apply the hosts, and a vCenter Server folder or cluster for each host.
The architecture of vSphere Auto Deploy is designed to automate the deployment and management of ESXi hosts at scale. It involves several key components that work together to provision hosts dynamically based on predefined rules and configurations. Here is an overview of vSphere Auto Deploy architecture.
To have Auto Deploy in VMware, you can achieve mass deployment and can reduce the risk of configuration drift. But when head to setup VMware we need to know the basic things to do before, during and after deployment. Next, are some steps to figure out things ought to do.
Before you start using vSphere Auto Deploy, you must make sure that the environment can adapt the process and the deployment can go smoothly. Here is a checklist to guide you through the preparation phase.
1. System Requirement
★ vCenter Server: Ensure that you have a functioning vCenter Server, either the Windows-based version or the vCenter Server Appliance.
★ ESXi Hosts: Verify that the ESXi hosts are compatible with the vSphere version you plan to use.
★ vSphere Web Client: Make sure you can access the vSphere Web Client, as this is necessary for managing Auto Deploy.
2. Network Requirement
▶ DHCP Server: A DHCP sever is requiring to assign IP addresses to ESXi hosts during network boot.
▶ TFTP Server: Install and configure a TFTP server the boot files to ESXi hosts. Common TFTP server include Tftpd32 (Windows) or dnsmasq (Linux).
▶ PXE Boot Configuration: Ensure that the ESXi hosts are configured to boot from the network in their BIOS/UEFI settings.
3. Software and Licensing
♦ vSphere Auto Deploy Service: Verify that the Auto Deploy service is installed and running on the vCenter Server.
♦ Image Builder: The Image Builder service should be installed and configured if you plan to create or customize ESXi image profiles.
♦ vSphere PowerCLI: Install vSphere PowerCLI on a management workstation. This is required for creating and managing deploy rules, image profiles and host profiles.
Step 1. Log into the vSphere Web Client, navigate to Administration Auto Deploy Enable Auto Deploy and Image Builder.
Step 2. Verify the DHCP server is correctly providing PXE boot options.
Step 3. Open vSphere PowerCLI and create deploy rules. Use the following PowerCLI cmdlet to write a rule that assigns the image profile to hosts.
Step 4. Configuration the ESXi hosts to boot from the network.
Step 5. Use the vSphere Web Client to monitor the deployment progress.
Tips: You can type cmdlets in PowerCLI
✐ Get help by running Get-Help cmdlet_name.
✐ You can format the output of any variable or cmdlet using Format-List or Format-Table, or their abbreviations f1 or ft.
✐ For additional details, you can use the Get-Help Format-List cmdlet.
After the deployment is finished, what we need to do is to ensure they comply with the host profile and regularly monitor the Auto Deploy service. With these, we can ensure they remain compliant with the desired configuration and remediate any hosts that do not match the profile settings.
By following these structures of approach to ensure a smooth setup process for VMware Auto Deploy, also can reduce the risk of issues and ensure a successful deployment.
In a large-scale or dynamic environments, it’s an optional idea to setup VMware Auto Deploy. In this way, it can offer you the ability to deploy hundreds or even thousands of hosts simultaneously. With the condition, a security backup solution is what you need.
AOMEI Cyber Backup is an easy-to-use and powerful VMware backup solution which provide you with the needing of virtual environments. It offers comprehensive features for ensuring the security and integrity of your virtual machines (VMs).

VMware Auto Deploy is a powerful tool designed to automate and streamline the deployment of ESXi hosts in large-scale or dynamic vSphere. By leveraging Auto Deploy, it can achieve consistent, scalable, and flexible deployments, ensuring that all hosts are configured uniformly and managed centrally. It’s an invaluable tool for modern data centers, significantly enhances operational efficiency.
