When upgrading a system, do not flash the BIOS, because this action can change aliases. Flashing the
BIOS to the latest level is more appropriate for fresh install.
Set up a Highly Available Auto Deploy Infrastructure
In many production situations, a highly available Auto Deploy infrastructure is required to prevent data
loss. Such an infrastructure is also a prerequisite for using Auto Deploy with stateless caching.
Prerequisites
For the management cluster, install ESXi on three hosts. Do not provision the management cluster hosts
with Auto Deploy.
Procedure
1 Enable vSphere HA and vSphere DRS on the management cluster.
2 Set up the following virtual machines on the management cluster.
Infrastructure component Description
PXE boot infrastructure
TFTP and DHCP servers.
Infrastructure VM
Active Directory, DNS, vCenter Server.
Auto Deploy environment
PowerCLI, Auto Deploy server, vCenter Server. Set up this environment
on a single virtual machine or on three separate virtual machines in
production systems.
The vCenter Server on the infrastructure virtual machine differs from the vCenter Server in the Auto
Deploy environment.
3 Set up Auto Deploy to provision other hosts as needed.
Because the components on the management cluster are protected with vSphere HA, high availability is
supported.
