In many production situations, a highly available Auto Deploy infrastructure is required to prevent data loss. Such infrastructure is also a prerequisite for using Auto Deploy with stateless caching.
About this task
For the management cluster, install ESXi on three hosts. Do not provision the management cluster hosts with Auto Deploy.
Watch the video "Highly Available Auto Deploy Infrastructure" for information about the implementation of a highly available Auto Deploy infrastructure:
- Enable vSphere HA and vSphere DRS on the management cluster.
- Set up the following virtual machines on the management cluster.
PXE boot infrastructure
TFTP and DHCP servers.
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.
- 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.
