Tag: Auto Deploy

You learned about VMware Auto Deploy’s benefits in part one of our two-part series, but it’s also important to know the vSphere 5 feature’s nuts and bolts and how to set it up for customers.

Auto Deploy takes advantage of the Preboot Execution Environment (PXE) boot feature that is present in many physical network interface cards (NICs). This allows a server to boot from a remote image file using only a physical NIC and without local storage.

A server booting with PXE first obtains an IP address using Dynamic Host Configuration Protocol (DHCP) and then loads a boot image from a Trivial File Transfer Protocol (TFTP) server. Auto Deploy uses PXE booting to download an ESXi image file to a host and its components work to define which image a host should use, customizations and host-specific configuration information.

Auto Deploy relies on software depots that are used to store collections of vSphere Installation Bundles (VIB) and image files that are accessed remotely via HTTP to deploy or update hosts. VIB files are used to deploy the ESXi software and any hardware vendor customizations. The Auto Deploy Server uses the software depot to pull VIBs and image profiles when booting an ESXi host.

Although creating new hosts is a common server virtualization task, it is also a tedious process. Solution providers can use VMware Auto Deploy for vSphere 5 to do it much more efficiently.

Installing single hosts isn’t hard for solution providers but configuring multiple hosts can be time consuming. A VAR that has to create a new vSphere host without VMware Auto Deploy typically has to do the following:

1. Locate the installation media for ESX or ESXi and boot the server from it.

2. Follow the setup prompt to set configuration information.

3. Complete the installation and then reboot the server.

4. Verify that management console networking works properly.

5. Add the host to vCenter Server.

6. Configure networking, storage, security and other settings.

In doing all this, you risk making mistakes during the build process and could configure hosts inconsistently. Consistency is very important in a virtual environment both from a security and operational perspective. Once you’ve built and configured a host, another challenge is to back up host configuration data so if a problem occurs and you need to rebuild the host, you don’t have to restart from scratch.
