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.

CSDDC-CMP-032

Create at least one workload reservation policy in vRealize Automation

Use reservation policies to target a deployment to a specific set of reservations. Reservation policies are also used to target workloads in their respective vSphere resource pool.

None.

Create at least one reservation policy for the placement of dynamically created edge services gateways.

Places the edge devices in their respective 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.

Design Implication

CSDDC-CMP-034

Do not use storage tiers.

The underlying physical storage design does not use storage tiers.

Both business groups have access to the same storage. Cusotmers using multiple datastores with different storage capabilities must evaluate the usage of vRealize Automation storage reservation policies.
