Learn the different management techniques used with ESXi by installing the v Sphere command-line interface (CLI) on your workstations and installing the v Sphere Management Assistant (v MA) onto a host. You should also experiment with the Tech Support Mode console, which can be accessed remotely or locally.
To experiment, set up a test environment so you don't affect your production environment.If you don't have spare hardware, you can run ESXi inside a virtual machine (VM) on an ESX host or with VMware Workstation.This includes backup and hardware monitoring agents.Check with vendors to make sure they have a technology that supports ESXi. Although VMware is working to ensure third-party software compatibility, don't assume that any software will work with ESXI -- at least not the version of the software with which you are familiar.To get these agents you typically have to download a special copy of ESXi from the server manufacturer's website, as the ESXi installable file on VMware's website only contains standard, nonvendor specific Common Information Model providers.

If you use Perl scripts inside the Service Console, you should consider Power Shell, the v Sphere CLI or v MA.
