Track your equipment assets such as computers and servers using hardware
models.

## Before you begin

Important:  
Starting with the Xanadu release, the legacy Technology Lifecycle Management module is moved to the Enterprise Architecture Workspace. To learn more, see [Managing the Technology Lifecycle Management (TLM) in Enterprise Architecture Workspace](https://www.servicenow.com/docs/udaB7kbGeAWr5r4c9CLyeg "Technology Lifecycle Management helps Enterprise Architects to manage technology life-cycle risks and technology life-cycle exceptions. Enterprise Architects can evaluate all their business applications and application services by accessing the discovered technologies and auditing information in the Enterprise Architecture Workspace.").

Role required: sn_apm.apm_user

## About this task

Hardware models are configuration items with specifications for a given device model. Specifications can be size, depth, image, model, and power of the device.  
Note:  
In Enterprise Architecture, only computers and servers are tracked as hardware or hardware models. Other types of hardware such as printers, network gear, peripherals, or UPS are not tracked for an application service.

Your business applications may run on multiple application services, which in turn
can be installed on different types of hardware. Therefore associating application
services with hardware models helps to know the risk on the Application Service due
to underlying hardware.

When you run the Fetch Product Models job, the application service is automatically
associated with a hardware model. The application service and the hardware product
model are mapped and a record is created in the Application Service Hardware Models
\[sn_apm_tpm_app_service_hardware_model\] table. However, you can also manually
associate an application service to all hardware models, including the hardware.

After the Load TPM Risk Parameters and compute Application Service Risks scheduled
job is executed, the technology risk data of the hardware model are generated and
stored in Hardware Model Risks \[sn_apm_tpm_hardware_model_risk\] table.  
Note:  
As an Enterprise Architecture user, your access to the hardware product model risk table is limited to read-only. However, if you are an Enterprise Architecture administrator you can create, modify, and delete the hardware model risks in the table. Access is also read-only to Hardware \[cmdb_ci_hardware\], Hardware Model \[cmdb_hardware_product_model\], and Hardware Model Lifecycle \[cmdb_hardware_model_lifecycle\] tables.

## Procedure

1. Navigate to AllApplication Portfolio ManagementTechnology Portfolio Management (TPM)Application Services.
2. Click the service record, which is the application service, to which you want to associate a hardware model.
3. Click the Application Service Hardware Models related list.
4. Click New.  
   The Application service hardware models database table stores the application
   service hardware model information. You can also navigate directly to the
   Application Service Hardware Models table from the application
   navigator.
5. On the form, fill in the fields.  
   For field information, see [Application Service Hardware Models form](https://www.servicenow.com/docs/PuLbmY22JDiyMkbwdkOaQw "Track your equipment assets such as computers and servers using hardware models.").
6. Click Submit.
