Design Decision

Design Justification

Design Implication

CSDDC-VI-VC-005

Deploy a vCenter Server Appliance of a small deployment size or larger.

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

If the size of the environment changes, the vCenter Server Appliance size might need to be increased.
