You use the preboot execution environment (PXE) to boot a host and launch the ESXi installer from a network interface.

ESXi 5.x is distributed in an ISO format that is designed to install to flash memory or to a local hard drive. You can extract the files and boot using PXE.

PXE uses DHCP and Trivial File Transfer Protocol (TFTP) to boot an operating system over a network.

PXE booting requires some network infrastructure and a machine with a PXE-capable network adapter. Most machines that are capable of running ESXi have network adapters that are able to PXE boot.

Note:

Ensure that the Auto Deploy server has an IPv4 address. PXE booting is supported only with IPv4.
