managed by vSphere Auto Deploy and pin the vCenter Server virtual machine to these hosts
by using a rule (vSphere HA DRS required VM to host rule). You can set up the rule and then
deactivate DRS if you do not want to use DRS in the cluster. The greater the number of hosts
that are not managed by vSphere Auto Deploy, the greater your resilience to host failures.
Note This approach is not suitable if you use Auto Start Manager. Auto Start Manager is not
supported in a cluster enabled for vSphere HA.
vSphere Auto Deploy Networking Best Practices
Prevent networking problems by following vSphere Auto Deploy networking best practices.
vSphere Auto Deploy and IPv6
Because vSphere Auto Deploy takes advantage of the iPXE infrastructure, if the hosts that you
plan to provision with vSphere Auto Deploy are with legacy BIOS, the vSphere Auto Deploy
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.
