Reservation Policies
You can use a reservation policy to control how reservation requests are processed. When you provision
machines from the blueprint, provisioning is restricted to the resources specied in your reservation policy.
Reservation policies provide an optional means of controlling how reservation requests are processed. You
can apply a reservation policy to a blueprint to restrict the machines provisioned from that blueprint to a
subset of available reservations.
You can use a reservation policy to collect resources into groups for dierent service levels, or to make a
specic type of resource easily available for a particular purpose. When a user requests a machine, it can be
provisioned on any reservation of the appropriate type that has sucient capacity for the machine. The
following scenarios provide a few examples of possible uses for reservation policies:
n
To ensure that provisioned machines are placed on reservations with specic devices that support
NetApp FlexClone.
n
To restrict provisioning of cloud machines to a specic region containing a machine image that is
required for a specic blueprint.
n
As an additional means of using a Pay As You Go allocation model for machine types that support that
capability.
You can add multiple reservations to a reservation policy, but a reservation can belong to only one policy.
You can assign a single reservation policy to more than one blueprint. A blueprint can have only one
reservation policy.
N Reservations dened for vCloud Air endpoints and vCloud Director endpoints do not support the
use of network proles for provisioning machines.
N If you have SDRS enabled on your platform, you can allow SDRS to load balance storage for
individual virtual machine disks, or all storage for the virtual machine. If you are working with SDRS
datastore clusters, conicts can occur when you use reservation policies and storage reservation policies. For
example, if a standalone datastore or a datastore within an SDRS cluster is selected on one of the
reservations in a policy or storage policy, your virtual machine storage might be frozen instead of driven by
SDRS. If you request reprovisioning for a machine with storage placement on an SDRS cluster, the machine
is deleted if the SDRS automation level is disabled.
Configure a Reservation Policy
You can create reservation policies to collect resources into groups for dierent service levels, or to make a
specic type of resource easily available for a particular purpose. After you create the reservation policy, you
then must populate it with reservations before tenant administrators and business group managers can use
the policy eectively in a blueprint.
A reservation policy can include reservations of dierent types, but only reservations that match the
blueprint type are considered when selecting a reservation for a particular request.
Procedure
1 Create a Reservation Policy on page 219
You can use reservation policies to group similar reservations together.
2 Assign a Reservation Policy to a Reservation on page 219
You can assign a reservation policy to a reservation when you create the reservation. They can also edit
an existing reservation to assign a reservation policy to it, or change its reservation policy assignment.
