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 multiple storage paths are available on a reservation with sufficient capacity to provision the machine
volumes, storage paths are selected according to the following logic:
n
If the blueprint or request specifies a storage reservation policy, the storage path must belong to that
storage reservation policy.
If the value of the custom property VirtualMachine.DiskN.StorageReservationPolicyMode is NotExact
and there is no storage path with sufficient capacity within the storage reservation policy, then
provisioning can proceed with a storage path outside the specified storage reservation policy. The
default value of VirtualMachine.DiskN.StorageReservationPolicyMode is Exact.
n
If multiple storage paths have the same priority, machines are distributed among storage paths in
round-robin fashion.
Creating a vSphere Reservation for NSX Network and Security Virtualization
You can create a vSphere reservation to assign external networks and routed gateways to network
profiles for networks, specify the transport zone, and assign security groups to machine components.
If you have configured VMware NSX, and installed the NSX plug-in for vRealize Automation, you can
specify NSX transport zone, gateway reservation policy, and app isolation settings when you create or
edit a blueprint. These settings are available on the NSX Settings tab on the New Blueprint and
Blueprint Properties pages.
The network and security component settings that you add to the blueprint design canvas are derived
from your NSX configuration and require that you have installed the NSX plug-in and run data collection
for the NSX inventory for vSphere clusters. Network and security components are specific to NSX and are
available for use with vSphere machine components only. For information about configuring NSX, see
NSX Administration Guide.
When vRealize Automation provisions machines with NAT or routed networking, it provisions a routed
gateway as the network router. The routed gateway is a management machine that consumes compute
resources. It also manages the network communications for the provisioned machine components. The
reservation used to provision the routed gateway determines the external network used for NAT and
routed network profiles. It also determines the reservation routed gateway used to configure routed
networks. The reservation routed gateway links routed networks together with entries in the routing table.
You can specify a routed gateway reservation policy to identify which reservations to use when
provisioning the machines using the routed gateway. By default, vRealize Automation uses the same
reservations for the routed gateway and the machine components.
