A compute resource can also have multiple reservations for multiple business groups. In the case of
virtual reservations, you can reserve more resources across several reservations than are physically
present on the compute resource. For example, if a storage path has 100 GB of storage available, a
fabric administrator can create one reservation for 50 GB of storage and another reservation using the
same path for 60 GB of storage. You can provision machines by using either reservation as long as
sufficient resources are available on the storage host.
Configuring Reservation Policies
When a user requests a machine, it can be provisioned on any reservation of the appropriate type that
has sufficient capacity for the machine. 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 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.
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.
Machine Blueprints
A blueprint that contains a machine component specifies the workflow used to provision a machine and
includes information such as CPU, memory, and storage. Machine blueprints specify the workflow used to
provision a machine and include additional provisioning information such as the locations of required disk
images or virtualization platform objects. Blueprints also specify policies such as the lease period and can
include networking and security components such as security groups, policies, or tags.
A machine blueprint typically refers to a blueprint that contains only one machine component and the
associated security and networking elements. It can be published as a standalone blueprint and made
available to users in the service catalog. However, published machine blueprints also become available
for reuse in your design library, and you can assemble multiple machine blueprints, along with Software
components and XaaS blueprints, to design elaborate application blueprints for delivering catalog items
that include multiple machines, networking and security, software with full life cycle support, and custom
XaaS functionality to your users.
