Design Justification

Design Implication

ROBO-VI-VC-005

In each ROBO, deploy a vCenter Server Appliance of a small deployment size.

Based on the number of management and workload virtual machines that a ROBO deployment runs, a vCenter Server Appliance installed with the small size setting is sufficient.

A small vCenter Server deployment supports up to 100 hosts or 1,000 virtual machines, which is more than a ROBO is designed for.
