Most vRealize Automation appliance requirements are preconfigured in the OVF or OVA that you deploy. The same requirements apply to standalone, master, or replica vRealize Automation appliances.

The minimum virtual machine hardware on which you can deploy is Version 7, or ESX/ESXi 4.x or later. See VMware Knowledge Base article 2007240. Because of the hardware resource demand, do not deploy on VMware Workstation.

After deployment, you might use vSphere to adjust vRealize Automation appliance hardware settings to meet Active Directory requirements. See the following table.

Table 1. vRealize Automation Appliance Hardware Requirements for Active Directory
