Recommended hardware configuration is two or more computers for Hardware Nodes.
Note: Parallels Business Automation - Standard can work well with just one Hardware Node, but existence of two nodes increases availability of the hosting service. With two or more nodes one of them may be taken off-line for maintenance, replacement or upgrade with minimal disruption for the hosting service.
If you use Parallels Virtuozzo Containers, we recommend installing the Management Node software in a special service Container hosted on one of your Hardware Nodes. In this case that single computer shall meet both Hardware Node and Management Node requirements and you then need at least one workstation for system administrator to manage it.
However, you can have your Management Node as a separate computer.
