A system plan for a single symmetric multiprocessing server having a plurality of computing nodes with a single hypervisor that spans across the plurality of computing nodes may be created based upon user defined parameters. Based upon the user defined parameters, an asymmetric cabling structure between the computing nodes of the single symmetric multiprocessing server for the system plan may be determined. In response to determining the asymmetric cabling structure, the system plan may be displayed to a user through a graphical user interface.
