Description

Summarize your machine component for the benefit of other architects.

Display location on request

In a cloud environment, such as vCloud Air, this allows users to select a region for their provisioned machines.

For a virtual environment, such as vSphere, you can configure the locations feature to allow users to select a particular data center location at which to provision a requested machine. To fully configure this option, a system administrator adds data center location information to a locations file and a fabric administrator edits a compute resource to associate it with a location.

See Scenario: Add Datacenter Locations for Cross Region Deployments and Scenario: Apply a Location to a Compute Resource for Cross Region Deployments.

Reservation policy

Apply a reservation policy to a blueprint to restrict the machines provisioned from that blueprint to a subset of available reservations. Fabric administrators create reservation policies to provide an optional and helpful means of controlling how reservation requests are processed, for example to collect resources into groups for different service levels, or to make a specific type of resource easily available for a particular purpose. If your fabric administrator did not configure reservation policies, you do not see any available options in this drop-down menu.

For information about creating reservation policies, see Configure a Reservation Policy.

Machine prefix

Machine prefixes are created by fabric administrators and are used to create the names of provisioned machines. If you select Use group default, machines provisioned from your blueprint are named according to the machine prefix configured as the default for the user's business group. If no machine prefix is configured, one is generated for you based on the name of the business group.

If your fabric administrator configures other machine prefixes for you to select, you can apply one prefix to all machines provisioned from your blueprint, no matter who the requestor is.

For information about creating machine prefixes, see Configure Machine Prefixes.

Instances: Minimum and Maximum

Configure the maximum and minimum number of instances users can request for a deployment or for a scale in or scale out action. If you do not want to give users a choice, entering the same value in the Minimum and Maximum fields configures exactly how many instances to provision and disables scale actions against this machine component.

XaaS components are not scalable and are not updated during a scale operation. If you are using XaaS components in your blueprint, you could create a resource action for users to run after a scale operation, which could either scale or update your XaaS components as required. Alternatively, you could disable scale by configuring exactly the number of instances you want to allow for each machine component.

Build Information Tab

Configure build information settings for a vCloud Air machine component.

Table 2. Build Information Tab

Setting

Description

Blueprint type

For record-keeping and licensing purposes, select whether machines provisioned from this blueprint are classified as Desktop or Server.

Action

The options you see in the action drop-down menu depend on the type of machine you select.

The following actions are available:

  • Clone

    Make copies of a virtual machine from a template and customization object.

Provisioning workflow

The options you see in the provisioning workflow drop-down menu depend on the type of machine you select, and the action you select.

The following actions are available:

  • CloneWorkflow

    Make copies of a virtual machine, either by clone, linked clone, or Netapp Flexclone.

Clone from

For clone or NetApp FlexClone, select a machine template to clone from.

For linked clones, select a machine from the list of machines. You only see machines that have available snapshots to clone from and that you manage as a tenant administrator or business group manager.

You can only clone from templates that exist on machines that you manage as a business group manager or tenant administrator.

Machine Resources Tab

Specify CPU, memory and storage settings for your vCloud Air machine component.

Table 3. Machine Resources Tab

Setting

Description

CPUs: Minimum and Maximum

Enter a minimum and maximum number of CPUs that can be provisioned by this machine component.

Memory (MB): Minimum and Maximum

Enter a minimum and maximum amount of memory that can be consumed by machines that are provisioned by this machine component.

Storage (GB): Minimum and Maximum

Enter a minimum and maximum amount of storage that can be consumed by machines that are provisioned by this machine component. For vSphere, KVM (RHEV), SCVMM, vCloud Air, and vCloud Director, minimum storage is set based on what you enter on the Storage tab.

Storage Tab

You can add storage volume settings, including one or more storage reservation policies, to the machine component to control storage space.

Table 4. Storage Tab Settings

Setting

Description

ID

Enter an ID or name for the storage volume.

Capacity (GB)

Enter the storage capacity for the storage volume.

Drive Letter/Mount Path

Enter a drive letter or mount path for the storage volume.

Label

Enter a label for the drive letter and mount path for the storage volume.

Storage Reservation Policy

Enter the existing storage reservation policy to use with this storage volume.

Custom Properties

Enter any custom properties to use with this storage volume.

Maximum volumes

Enter the maximum number of allowed storage volumes that can be used when provisioning from the machine component. Enter 0 to prevent others from adding storage volumes. The default value is 60.

Allow users to see and change storage reservation policies

Select the check box to allow users to remove an associated reservation policy or specify a different reservation policy when provisioning.

Properties Tab

Optionally specify custom property and property group information for your vCloud Air machine component.

You can add individual and groups of custom properties to the machine component by using the Properties tab. You can add also custom properties and property groups to the overall blueprint by using the Properties tab when you create or edit a blueprint by using the New Blueprint or Blueprint Properties page, respectively.

You can use the Custom Properties tab to add and configure options for existing custom properties. Custom properties are supplied with vRealize Automation and you can also create property definitions.

Table 5. Properties > Custom Properties Tab Settings

Setting

Description

Name

Enter the name of a custom property or select an available custom property from the drop-down menu. For example, enter the custom property name Machine.SSH to specify whether machines provisioned by using this blueprint allow SSH connections. Properties only appear in the drop-down menu if your tenant administrator or fabric administrator created property definitions.

Value

Enter or edit a value to associate with the custom property name. For example, set the value as true to allow entitled users to connect by using SSH to machines provisioned by using your blueprint.

Encrypted

You can choose to encrypt the property value, for example, if the value is a password.

Overridable

You can specify that the property value can be overridden by the next or subsequent person who uses the property. Typically, this is another architect, but if you select Show in request, your business users are able to see and edit property values when they request catalog items.

Show in Request

If you want to display the property name and value to your end users, you can select to display the property on the request form when requesting machine provisioning. You must also select overridable if you want users to provide a value.

You can use the Property Groups tab to add and configure settings for existing custom property groups. You can create your own property groups or use property groups that have been created for you.

Table 6. Properties > Property Groups Tab Settings

Setting

Description

Name

Select an available property group from the drop-down menu.

Move Up and Move Down

Control the precedence level of listed property groups in descending order. The first-listed property group has precedence over the next-listed property group and so on.

View Properties

Display the custom properties in the selected property group.

View Merged Properties

Display all the custom properties in the listed property groups in the order in which they appear in the list of property groups. Where the same property appears in more than one property group, the property name appears only once in the list based on when it is first encountered in the list.
