Table 2. vCenter Server Appliance Sizing Design Decisions

Decision ID

Design Decision

Design Justification

Design Implication


Configure the vCenter Server Appliance with at least the small size setting.

Based on the number of hosts and virtual machines in a consolidated pod, a vCenter Server Appliance installed with the small size setting is sufficient.

If the size of the environment grows past 100 hosts or 1000 virtual machines, the vCenter Server Appliance size will need to be increased.
