You can add each virtual reservation to one reservation policy. The reservation from which a particular virtual machine is provisioned is determined by vRealize Automation based on the reservation policy specified in the blueprint, if any, the priorities and current usage of the fabric group's reservations, and other custom properties.

Decision ID Design Decision Design Justification Design Implication
CSDDC-CMP-035 Create at least one workload reservation policy in vRealize Automation. Places a deployment on a specific set of reservations. You also use reservation policies a to place workloads in the allocated vSphere resource pool. None.
CSDDC-CMP-036 Create at least one reservation policy for the placement of dynamically created edge services gateways. Places the edge devices in the allocated vSphere resource pools. None.

A storage reservation policy is a set of datastores that can be assigned to a machine blueprint to restrict disk provisioning to only those datastores. Storage reservation policies are created and associated with the appropriate datastores and assigned to reservations.

CSDDC-CMP-037 In this design, do not use storage tiers. The underlying physical storage design does not use storage tiers.
  • Both business groups, Production and Development, have access to the same storage.
  • Tenants using multiple datastores with different storage capabilities must evaluate the use of vRealize Automation storage reservation policies.
