Packaging design challenges of the IBM System z10 Enterprise Class server

This paper describes the system packaging and technologies of the IBM System z10™ high-end Enterprise Class server. This machine exceeds the multiprocessor performance of the previous system by 50%. A new generation of the IBM Elastic Interface was developed in order to maintain the increased interconnect signal speed of up to 2.93 Gb/s. Power control and power delivery to the multicore processors were a special challenge for the server packaging because of the high currents and the high number of voltage domains.
