# Resource Tree

The Resource Tree displays and organizes resources of the following types:

- Device Type: Organize resources by device types, Switch and HFI

- PmPortGroups: Organize resources by PM Port Groups

- Virtual Fabric: Organize resources by defined virtual fabric

Although the resources are organized differently in the Resource Tree, there are only three types of resources, as described below. Click a resource to display the performance information in the right panel.

- Device Set: A set of device nodes, such as a subnet, a device group, a virtual fabric, or a type of device

- Device Node: A fabric node that can be either a switch or HFI

- Device Port: A port in a fabric node
