Abstract: A modular case having similarly sized U-shaped sections that enclose energy storage cells and a battery management system. Additional modules can be ganged together to increase the energy storage and output capacity. Removable panels in the sections can be removed for the installation of jacks and a status display. Various charging sources can be coupled to the module including solar, generator and AC mains for charging. An output switch selectively delivers AC mains power when available, and then switches to battery power during periods of AC mains unavailability.

Abstract: The management of serviceability in a cloud of computing resources. The computing resources available in the cloud are represented for access control purposes as a hierarchy of nodes. Upon receiving a request to perform an action on a computing resource, the associated hierarchical node that controls the action with respect to the requestor is identified. Then, the associated access privilege of that hierarchical node is identified. In some embodiments, if it is determined that the requestor has rights to perform the action on the computing resource, the action is facilitated.
