The present invention, in various embodiments, provides techniques for managing memory in computer systems. The number of the internal switching system is entered into the numbering of the port of the virtual switching system thus making a standardized user interface of the switching system become available. The method may further include restricting a subset of the plurality of processing nodes from differentiating into a role. The insulation between the active part and the housing is ensured by a dielectric sleeve. The semicrystalline polyolefin has a density of at least 0.
