Component names (xnames) identify the geolocation for hardware components in the HPE Cray EX system. Every component is uniquely identified by these component names. Some, like the system cabinet number or the CDU number, can be changed by site needs. There is no geolocation encoded within the cabinet number, such as an X-Y coordinate system to relate to the floor layout of the cabinets. Other component names refer to the location within a cabinet and go down to the port on a card or switch or the socket holding a processor or a memory DIMM location.
