2 Click Generate Ranges to generate network ranges based on the subnet mask, range subnet mask, and
base IP address information that you entered on the General tab.
Starting with the base IP address, vRealize Automation generates ranges based on the range subnet
mask.
For example, vRealize Automation generates ranges of 255 IP ranges if the subnet mask is 255.255.0.0
and the range subnet mask is 255.255.255.0 using the name Range1 through Rangen.

Configuring Reservations and Reservation Policies
A vRealize Automation reservation can dene policies, priorities, and quotas that determine machine
placement for provisioning requests. Reservation policies restrict machine provisioning to a subset of
available reservations. Storage reservation policies allow blueprint architects to assign machine volumes to
dierent datastores.
Reservations
You can create a vRealize Automation reservation to allocate provisioning resources in the fabric group to a
specic business group.
For example, you can use reservations to specify that a share of the memory, CPU, networking, and storage
resources of a single compute resource belongs to a particular business group or that certain machines be
allocated to a specic business group.
N Note: Storage and memory that are assigned to a provisioned machine by a reservation are released
when the machine to which they are assigned is deleted in vRealize Automation by the Destroy action. The
storage and memory are not released if the machine is deleted on the vCenter Server.
You can create a reservation for the following machine types:
n
vSphere
n
vCloud Air
n
vCloud Director
n
Amazon
n
Hyper-V
n
KVM
n
OpenStack
n
SCVMM
n
XenServer
Choosing a Reservation Scenario
You can create reservations to allocate resources to business groups. Depending on your scenario, the
procedure to create a reservation diers.
Choose a reservation scenario based on the target endpoint type.
Each business group must have at least one reservation for its members to provision machines of that type.
For example, a business group with an OpenStack reservation but not an Amazon reservation, cannot
request a machine from Amazon. In this example, the business group must be allocated a reservation
specically for Amazon resources.
