On the occasions when an ESX Server fails—or more likely, when you have to restart it on another physical machine to reconfigure your site—the last thing you’ll want is to have to step through the complex startup process manually. It’s slow and error-prone, and practically negates the value of virtualizing your servers in the first place. Nearly every site, therefore, automates the startup.
