Abstract: The present invention provides a modular chassis comprising of multiple thin-client blades removeably connectable to a common midplane and to one or more power supplies and one or more management modules to simulate multiple thin-client operating with one or more computer networks. The invention enables building large-scale computer laboratory environments having many thin-client devices and possibly many simulated users, easily connected and managed to simulate large computer infrastructure. Also disclosed in this patent is a method for performing combinations of functions including testing and simulation of normal and abnormal operational scenarios in complex server-based computing environments.

Abstract: The present invention is directed to provide a compact computing apparatus fit to be mounted on the wall or floor adjacent to or embedded inside the LAN jack or a main power outlet. The compact computing apparatus is optionally connected at the backside through Ethernet cable to the building LAN and connected at the front side through cables or wirelessly to display, keyboard, mouse or other peripheral devices. In a typical embodiment of the present invention power to the computing apparatus is supplied through the LAN cable. Another embodiment of the present invention utilizes a wall or floor mounted housing part comprising of an integrated LAN connector. In the preferred embodiment of the invention the computing apparatus has layered structure.
