Running a script is an efficient way to deploy multiple ESXi hosts with an unattended installation.
The installation script contains the host configuration settings. You can use the script to configure multiple hosts with the same settings. See Installing or Upgrading Hosts by Using a Script.
The installation script must be stored in a location that the host can access by HTTP, HTTPS, FTP, NFS, CDROM, or USB. You can PXE boot the ESXi installer or boot it from a CD/DVD or USB drive.
