ABSTRACT:
Systems and arrangements to adjust resource accessibility based upon usage modes are contemplated. Embodiments may include a supervisor instance such as an operating system that is adapted to select one or more supervisor keys from a set of supervisor keys available to the host node or platform upon which the supervisor instance is operating. The supervisor instance may select the supervisor key(s) based upon an association of the supervisor instance with a usage mode represented by a supervisor key name. In many embodiments, supervisor key names may be associated with resources via with one or more of the supervisor keys based upon the resources needed when operating in the usage modes by a system administrator. Once the supervisor instance is initialized, the supervisor instance may issue client keys that allow access to subsets of the resources available to the supervisor instance based upon usage modes of the clients.
