AutoDeploy a description November 12, 2012Posted by vbry21 in VMware blogs.
I’ve got a couple of ESXi hosts to deploy, but I don’t like having to configure my Hosts, wouldn’t it be great if I could get my vSphere environment to deploy and configure the hosts?
“What I can?”
Auto Deploy is a new method for provisioning ESXi hosts that first came along in vSphere 5.0 and continues in vSphere 5.1.
With Auto Deploy, vCenter Server loads the ESXi image directly into the host memory, think PXE boot; we load the image from the network.
When the host boots, the software image and optional configuration are streamed into the ESXi hosts memory. All changes made to the state of the ESXi host are stored in RAM. When the host is shut down, the state of the host is lost but can be streamed into memory again when the host is powered back on.
Unlike the other installation options, Auto Deploy does not store the ESXi state on the host disk. vCenter Server stores and manages ESXi updates and patching through an image profile and, optionally, the host configuration through a host profile.
Auto Deploy enables the rapid deployment of many hosts.
Auto Deploy simplifies ESXi host management by eliminating the necessity to maintain a separate boot image for each host.
A standard ESXi image can be shared across many hosts.
When a host is provisioned using Auto Deploy, the host image is decoupled from the physical server. The host can be recovered without having to recover the hardware or restore from a backup. Finally, Auto Deploy eliminates the need for a dedicated boot device, thus freeing the boot device for other uses.
