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
SDDC-CMP-041 Create at least one workload reservation policy for each region. Places a deployment on a specific set of reservations in each region. You also use reservation policies to place workloads into the right region, compute cluster and vSphere resource pool. None.
SDDC-CMP-042 Create at least one reservation policy for placement of dynamically created edge services gateways into the shared edge and compute clusters. Places the edge devices into the allocated shared edge and compute cluster and 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.

SDDC-CMP-043 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 usage of vRealize Automation storage reservation policies.
