Configure a Host Profile to Use Stateless Caching
When a host is set up to use stateless caching, the host uses a cached image if the vSphere Auto
Deploy Server is not available. To use stateless caching, you must configure a host profile. You can
apply that host profile to other hosts that you want to set up for stateless caching.

Configure a Host Profile to Enable Stateful Installs
To set up a host provisioned with vSphere Auto Deploy to boot from disk, you must configure a host
profile. You can apply that host profile to other hosts that you want to set up for stateful installs.
Introduction to Stateless Caching and Stateful Installs
You can use the System Cache Configuration host profile to provision hosts with vSphere Auto Deploy
stateless caching and stateful installs.
Examples of Stateless Caching and Stateful Installs
Hosts provisioned with
vSphere Auto Deploy
cache the image
(stateless caching)
Set up and apply a host profile for stateless caching. You can cache the
image on a local disk, a remote disk, or a USB drive. Continue provisioning
this host with vSphere Auto Deploy. If the vSphere Auto Deploy server
becomes unavailable, for example because hundreds of hosts attempt to
access it simultaneously, the host boots from the cache. The host attempts
to reach the vSphere Auto Deploy server after the boot operation to
complete configuration.
Hosts provisioned with
vSphere Auto Deploy
become stateful hosts
Set up and apply a host profile for stateful installs. When you provision a
host with vSphere Auto Deploy, the image is installed on the local disk, a
remote disk, or a USB drive. For subsequent boots, you boot from the disk.
The host no longer uses vSphere Auto Deploy.
Preparation
To successfully use stateless caching or stateful installs, decide how to configure the system and set the
boot order.
