server must have an IPv4 address. PXE booting with legacy BIOS firmware is possible only
over IPv4. PXE booting with UEFI firmware is possible with either IPv4 or IPv6.
IP Address Allocation
Use DHCP reservations for address allocation. Fixed IP addresses are supported by the host
customization mechanism, but providing input for each host is not recommended.
VLAN Considerations
Use vSphere Auto Deploy in environments that do not use VLANs.
If you intend to use vSphere Auto Deploy in an environment that uses VLANs, make sure that
the hosts that you want to provision can reach the DHCP server. How hosts are assigned to
a VLAN depends on the setup at your site. The VLAN ID might be assigned by the switch or
the router, or might be set in the host's BIOS or through the host profile. Contact your network
administrator to determine the steps for allowing hosts to reach the DHCP server.
vSphere Auto Deploy and VMware Tools Best Practices
When you provision hosts with vSphere Auto Deploy, you can select an image profile that includes
VMware Tools, or select the smaller image associated with the image profile that does not contain
VMware Tools.
You can download two image profiles from the VMware download site.
n xxxxx-standard: An image profile that includes the VMware Tools binaries, required by
the guest operating system running inside a virtual machine. The image is usually named
esxi-
version
-
xxxxx
-standard.
n xxxxx-no-tools: An image profile that does not include the VMware Tools binaries. This
image profile is usually smaller has a lower memory overhead, and boots faster in a PXE-boot
environment. This image is usually named esxi-
version
-
xxxxx
-no-tools.
You can deploy ESXi using either image profile.
n If the network boot time is of no concern, and your environment has sufficient extra memory
and storage overhead, use the image that includes VMware Tools.
n If you find the network boot time too slow when using the standard image, or if you want to
save some space on the hosts, you can use the image profile that does not include VMware
Tools, and place the VMware Tools binaries on shared storage. See, Provision ESXi Host by
Using an Image Profile Without VMware Tools.
vSphere Auto Deploy Load Management Best Practices
Simultaneously booting large numbers of hosts places a significant load on the vSphere Auto
Deploy server. Because vSphere Auto Deploy is a Web server at its core, you can use existing
Web server scaling technologies to help distribute the load. For example, one or more caching
reverse proxy servers can be used with vSphere Auto Deploy. The reverse proxies serve up
