The GUI uses the term PVI cloud. PVI clouds are used with the fabric device to provide connections over the IB fabric to move non-data, non-I/O traffic around the network quickly. For example, you can use PVI clouds (and the PVI vNICs within them) for east-west traffic such as migrating one virtual machine from one server to another. For more information, refer to Working With PVI Clouds in Oracle Fabric Manager 5.0.2 Administration Guide.
