If the blueprint specifies a reservation policy, the reservation must belong to that reservation policy.
Reservation policies are a way to guarantee that the selected reservation satisfies any additional
requirements for provisioning machines from a specific blueprint.
For example, although a physical reservation is not restricted to a particular hardware type, the best
practice is to create reservations with only one type of physical machine and use reservation policies
to restrict provisioning from blueprints of a specific type to reservations containing only machines of
that type. This allows you to ensure that your HP iLO blueprints are correct for HP iLO provisioning,
and so on. For example, when you use a custom property in a blueprint to specify the location of a
boot disk, the value is a web URL for HP iLO machines but an NFS or CIFS path for Dell iDRAC
machines.
If no reservation is available that meets all of the selection criteria, provisioning fails.
If multiple reservations meet all of the criteria, the reservation from which to provision a requested
machine is determined by the following logic:
n
Reservations with higher priority are selected over reservations with lower priority.
n
If multiple reservations have the same priority, the reservation with the lowest percentage of its
machine quota allocated is selected.
n
If multiple reservations have the same priority and quota usage, machines are distributed among
reservations in round-robin fashion.
If there are multiple unprovisioned machines in the selected reservation, machine is selected for
provisioning by the following process:
1 The first machine is evaluated against the resource specifications in the blueprint, including the
resource matching settings. For example, at least 2 CPUs and exactly 2 GB of memory, or exactly 4
CPUs and 4 GB.
2 If the machine matches the specifications, it is selected for provisioning. If it does not, the next
machine in sequence is evaluated, and so on.
Create a Physical Reservation
Before members of a business group can request machines, fabric administrators must allocate
resources to them by creating reservations.
Each business group must have at least one physical reservation for its members to provision physical
machines. Each physical machine can belong to only one reservation, but each reservation can contain
multiple physical machines.
