A. Create VM-VM anti-affinity rules - A VM-VM affinity rule specifies whether selected individual virtual machines should run on the same host or be kept on separate hosts. B. Set das.respectvmvmantiaffinityrules to false - Determines if vSphere HA enforces VM-VM anti-affinity rules. The default value is "true" and rules are enforced even if vSphere DRS is not enabled. In this case, vSphere HA does not fail over a virtual machine if doing so violates a rule

PVLANs divide the broadcast domain into multiple broadcast sub-domains and allow further isolating different devices within the same VLAN. They provide layer 2 isolation between ports within the same broadcast domain. For example: "Your ESXi host uses several networks. Use appropriate security measures for each network, and isolate traffic for specific applications and functions. For example, ensure that VMware vSphere vMotion traffic does not travel over networks where virtual machines are located. Isolation prevents snooping. Having separate networks is also recommended for performance reasons."

"Running a script is an efficient way to deploy multiple ESXi hosts" with an unattended installation.
