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 100GB of storage available, a fabric
administrator can create one reservation for 50GB of storage and another reservation using the same
path for 60GB of storage. You can provision machines by using either reservation as long as sufficient
resources are available on the storage host.
You can reserve physical machines only for a single business group. Because physical machines do not
belong to fabric groups, all fabric administrators can manage all physical machines and reserve them for
a particular business group.
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.
Reservation policies provide an optional and helpful means of controlling how reservation requests are
processed. A reservation policy is often used to collect resources into groups for different service levels,
or to make a specific type of resource easily available for a particular purpose. The following scenarios
provide a few examples of possible uses for reservation policies:
n
To ensure that machines provisioned from a virtual blueprint are placed on reservations with storage
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
To restrict provisioning of Cisco UCS physical machines to reservations on endpoints on which the
selected service profile template and boot policy are available
n
As an additional means of using a Pay As You Go allocation model for vApps
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. For more information
about how reservations are selected for provisioning a machine, see IaaS Configuration for Cloud
Platforms, IaaS Configuration for Physical Machines, or IaaS Configuration for Virtual Platforms.
Cost Profiles
Fabric administrators can associate compute resources and physical machines with cost profiles to
enable calculation of a machine’s cost. The cost is displayed to machine owners, requesters, approvers,
and administrators at various points in the request and provisioning life cycle.
A cost profile includes the following values for daily cost:
n
Cost per GB of memory capacity specified in the virtual blueprint or installed in the physical machine
