You can create a reservation to allocate provisioning resources in the fabric group to a specific business group.
A virtual reservation allocates a share of the memory, CPU and storage resources on a particular compute resource for a business group to use.
A business group can have multiple reservations on the same compute resource or different compute resources, or any number of reservations containing any number of machines.
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.
