Getting Familiar with UFM's Data Model
Overview of Data Model
UFM enables the fabric administrator to manage the fabric based on discovery data collected from the fabric. This data is mapped into model elements (objects) available to the end user via UFM REST API and UFM Web UI.
The fabric managed by UFM consists of a set of physical and logical objects, including their connections. The Object Model has a hierarchical object-oriented tree structure with objects as the tree elements. Each object defines an abstraction for physical or logical fabric elements.
The Physical Model represents the physical resources and connectivity topology of the Network. UFM enables discovery, monitoring and configuration of the managed physical objects.

Description |
|
N/A |
Port Object |
Represents the external physical port on switch or on Host Channel Adapter (HCA). A port is identified by its number. UFM provides InfiniBand standard management and monitoring capabilities on the port level. |
|
N/A |
Module Object |
Represents the Field Removable Unit, Line card, and Network card on switch or HCA on host. For NVIDIA Switches, Line and Network Cards are modeled as modules. |
|
Link Object |
Represents the physical connection between two active ports. |
|
N/A |
Cable Object |
Represents the physical cable or the transceiver connected to one of the link edges. |
|
Computer Object |
Represents the computer (host) connected to the Fabric. The UFM Agent installed on the host provides extended monitoring and management capabilities. Hosts without agents are limited to InfiniBand standard management and monitoring capabilities. |
|
Switch Object |
Represents the switch chassis in the Fabric. A Switch object is created for every NVIDIA Switch. Switches of other vendors are represented as InfiniBand Switches and limited by InfiniBand standard management and monitoring capabilities. |
|
Rack Object |
Represents the arbitrary group of switches or computers. When linked devices are shown as a group, the link is shown between the group and the peer object. |
