You can use a reservation policy to collect resources into groups for different service levels, or to make a
specific 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 sufficient 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 specific devices that support
NetApp FlexClone.
n
To restrict provisioning of cloud machines to a specific region containing a machine image that is
required for a specific 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.
Note Reservations defined for vCloud Air endpoints and vCloud Director endpoints do not support the
use of network profiles for provisioning machines.
Note 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, conflicts 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 different service levels, or to make
a specific 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 effectively in a blueprint.
A reservation policy can include reservations of different 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
You can use reservation policies to group similar reservations together.
2 Assign a Reservation Policy to a Reservation
You can assign a reservation policy to a reservation when you create the reservation. You can also
edit an existing reservation to assign a reservation policy to it, or change its reservation policy
assignment.
