When creating a Region in VCF Automation , multiple workload domains can be aggregated to provide capacity to Organizations. For consistent provisioning across domains, resource constructs must be uniform.

The VCF 9.0 Automation documentation specifies:

VM Classes must exist with identical names across integrated vCenters to ensure consistent deployment behavior.

Storage Classes must also be consistently defined across Supervisors to allow Kubernetes and VM workloads to consume storage predictably.

Region quotas (A) are applied after region creation.

Reserved VM Classes (C) are not a prerequisite unless specifically required for policy enforcement.

An Organization for VM Applications (D) is not required prior to region creation.

Thus, the administrator must validate:

Consistent VM Classes (B)

Consistent Storage Classes (E)
