Enabling Stateless Caching
ESXi servers deployed using AutoDeploy
require the Auto Deploy server to be available and reachable every time the host reboots. Prior to vSphere 5.1, if the network boot fails, the server did not have a source to continue the boot process. Now with vSphere 5.1, you can enable Stateless Caching that will add a level resiliency in case the network boot (PXE boot) fails. The Stateless Caching mode is enabled by editing the Host Profile associated to the ESX server.
How to do it…
The following procedure will help you enable Stateless Caching:
Select the Host Profile and navigate to Actions | Edit Host Profile.
At the Edit Host Profile wizard, click on Next to go to the Edit Host Profile page of the wizard.
Expand Advanced Configuration Settings and then check the System Image Cache Configuration checkbox.
On the right-pane, use the System Image Cache Profile Settings drop-down menu to select Enable stateless caching on the host from the list.
Once selected, it will show...
