Network inventory models

You define an inventory model in the Telecommunications Network Inventory application so that you can track the technical information from the manufacturer about a network asset such as the telco equipment or a network interface.

Inventory models overview

A network inventory model contains the assets, services, and the relationships that define the infrastructure of your telecommunications networks. An inventory model contains the metadata for the name, number, dimensions, compatible interface cards, and configurations from the manufacturer. When you instantiate an inventory record by using the design and assign function, your inventory record contains this standard manufacturer information. To learn more about how to create an inventory model record, see Create inventory models.

After you create the inventory models, you can then define the relationships between the various network model entities. You can also define the compatibility between these entities. To learn more about model relationships, see Network model relationships.

Types of inventory models

You can create the following types of inventory models:

Facility Models

A network interface model captures the physical characteristics and data about the behavior of a facility hardware, as designated by the product manufacturer. Facility hardware represents the power, HVAC, network, and their connectivity in a data center.

Equipment Models

An equipment model represents the metadata that is provided by a vendor or manufacturer for the equipment. It defines the consistent characteristics across the various instances that are created for the equipment. An instance is an individual occurrence of a network asset at a site or datacenter. To learn more, see Create an equipment model.

Equipment holder models

An equipment holder model represents the metadata for the representation of containers, including the bays, cabinets, cages, line ups, relay racks, and slots. A Container Type field refers to the type of container that the equipment model represents To learn more, see Create an equipment holder model.

The modeling guidelines for the slots vary according to the telecommunications service provider. The individual slot models are represented by the types of slots. Examples are a route processor slot, power slot, fan slot, or a generic slot model.. To learn more, see Create an equipment holder model.

Interface card models

A card model defines the card's metadata, which are the attributes that are consistent across the various instantiated cards of that model.. To learn more, see Create a card model.

Network interface models

A network interface model captures the physical characteristics and data about the behavior of a network interface, as designated by the product manufacturer. To learn more, see Create a network interface model.

Physical connection model

A physical connection model captures the metadata for the physical connection. To learn more, see Create a physical connection model.

Logical connection model

A logical connection model captures the metadata for the logical connections. To learn more, see Create a logical connection model.

Cable model

A cable model captures the metadata for the cable. To learn more, see Create a cable model.

Strand model

A strand model captures the metadata for the strand. To learn more, see Create a strand model.

Network topology model

A network topology model captures the metadata for the topology. To learn more, see Create a network topology model.

Network model relationships

A model relationship captures the relationships between the inventory models. By defining the relationships between the various network model entities, you can also define the compatibility between these entities.

When setting up model relationships, you select one of the following options in the Relationship Type field:

--None--

No network model relationship exists.

Rack to Slot

Relationship between a rack model and a slot model. This relationship indicates that the rack and the slot models are compatible with the equipment model.

Equipment to Slot

Relationship between an equipment model and a slot model. This relationship indicates that the number of slots and the slot models are compatible with the equipment model.

Note:

• The Parent product model field shows a list of all the equipment models related to the Telecommunications Network Inventory application.
• The Child product model field shows only the slot models.

Equipment to Network interface

Relationship between an equipment model and a network interface model. This relationship indicates the interface model and the number of interfaces that are compatible and supported with the equipment model.

Note:

• The Parent product model field shows a list of all the equipment models related to the Telecommunications Network Inventory application.
• The Child product model field shows a list of all the network interface models related to the Telecommunications Network Inventory application.

Slot to Interface Card

Relationship between a slot model and an interface card model. This relationship enforces the Root product model field where an equipment model or a card model should be selected.

Note:

• The Root product model field shows a list of all the equipment models related to the Telecommunications Network Inventory application.
• The Parent product model field shows the models of both the slots and subslots.
• The Child product model field shows a list of all the interface card models.

Interface card to Slot

Relationship between an interface card model and a slot model. This relationship indicates that the slot model is compatible with the interface card model.

Note:

• The Parent product model field shows a list of all the interface card models.
• The Child product model field shows only the models of the subslots.

Interface Card to Network interface

Relationship between an interface card model and a network interface model. This relationship indicates that the number of interfaces in the network interface model are compatible with the interface card model.

Note:

• The Parent product model field shows a list of all the interface card models.
• The Child product model field shows a list of all the network interface models.

Physical Connection to Logical Connection

Relationship between the models of a physical connection to a logical connection.

Note:

• The Parent product model field shows a list of all the physical connection models.
• The Child product model field shows a list of all the logical connection models.

Logical Connection to Logical Connection

Relationship between one logical connection model to another logical connection model.

Note:

• The Parent product model field shows a list of all the logical connection models.
• The Child product model field shows a list of all the logical connection models.

Physical Connection to Network Interface

Relationship between a physical connection to a network interface.

Note:

• The Parent product model field shows a list of all the physical connection models.
• The Child product model field shows a list of all the network interface models.

Logical Connection to Network Interface

Relationship between a logical connection to a network interface.

Note:

• The Parent product model field shows a list of all the logical connection models.
• The Child product model field shows a list of all the network interface models.

Rack to Equipment

Relationship between a rack and the equipment.

Note:

• The Parent product model field shows all equipment holders that have Container type as Rack.
• The Child product model field shows all equipment models related to the Telecommunications Network Inventory application.

Cabinet to Equipment

Relationship between a cabinet and the equipment.

Note:

• The Parent product model field shows all equipment holders that have Container type as Cabinet.
• The Child product model field shows all equipment models related to the Telecommunications Network Inventory application.
