Dell PowerEdge FN I/O Module Configuration Guide 9.10(0.0)

• Physical Entity: A physical entity or physical component represents an identifiable physical resource within a managed system. Zero or more logical entities may utilize a physical resource at any given time. Determining which physical components are represented by an agent in the EntPhysicalTable is an implementation-specific matter. Typically, physical resources (for example, communications ports, backplanes, sensors, daughter-cards, power supplies, and the overall chassis), which you can manage via functions associated with one or more logical entities, are included in the MIB.
• Containment Tree: Each physical component may be modeled as contained within another physical component. A containment-tree is the conceptual sequence of entPhysicalIndex values that uniquely specifies the exact physical location of a physical component within the managed system. It is generated by following and recording each entPhysicalContainedIn instance up the tree towards the root, until a value of zero indicating no further containment is found.
