Abstract: Embodiments of the present disclosure provide a method and apparatus of controlling a network node. The method comprises: providing a virtual PDU by using a computing device; and causing the virtual PDU to control power supply of the network node coupled to the virtual PDU according to a type of the network node. By means of the embodiments of the present disclosure, not only physical nodes can be controlled, but also virtual nodes can be controlled.

Abstract: Techniques for building and implementing computing systems with simulated hardware infrastructures are provided to support, for example, development and testing of management and orchestration software. For example, a system includes a processing platform comprising hardware resources, and a simulated computing system executing on top of the processing platform using the hardware resources. The simulated computing system comprises simulated elements including a simulated compute node, a simulated network switch device, and a simulated power distribution device. The simulated compute node comprises a simulated hardware processor and a simulated storage device. The system further comprises a test control interface configured to enable a user to test the simulated computing system by injecting an error into the simulated computing system. For example, error injection includes manipulating a behavior of one or more of the simulated elements and/or simulating a failure of one or more of the simulated elements.
