Which three attributes from a hardware model record are used for setting the normalized display...

Hardware model normalization is a feature that enables users to normalize the details, such as manufacturer, product, model, and device type, of hardware and consumable models1

Hardware model normalization uses the data from the models and compares it against the data in the Hardware Model Normalization Content Service, which is a cloud-based service that provides standardized and enriched information about hardware models1

Hardware model normalization sets the normalized display name for each model record based on three attributes: Name, Manufacturer, and Model number2

The normalized display name is a combination of these three attributes, separated by a hyphen, for example: Dell-Inc.-OptiPlex 70102

The normalized display name helps to identify and group models with similar properties and reduce duplicates and inconsistencies in the model catalog and the Configuration Management Database (CMDB)2
