vCenter Server Appliance Sizing Design Decisions

Decision ID

Design Decision

Design Justification

Design Implication

SDDC-VI-VC-008

Configure the management vCenter Server Appliances with at least the small size setting.

Based on the number of management VMs that are running, a vCenter Server Appliance installed with the small size setting is sufficient.

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

SDDC-VI-VC-009

Configure the compute vCenter Server Appliances with at least the large size setting.

Based on the number of compute workloads and NSX edge devices running, a vCenter Server Appliance installed with the large size setting is recommended.

As the compute environment grows resizing to X-Large or adding additional vCenter Server instances may be required.
