Deployment of arrangements of physical computing components coupled over a communication fabric are presented herein. In one example, a method includes coupling into a communication fabric a plurality of communication interfaces provided by a baseboard hosting a plurality data processing devices. The method includes establishing a one-hop latency in the communication fabric between the plurality of data processing devices and peripheral card slots, and establishing a two-hop latency in the communication fabric between the plurality of data processing devices and additional peripheral card slots. The method also includes establishing interconnect pathways between a plurality of communication switches that provide the one-hop latency through one or more cross-connect communication switches that provide the two-hop latency.
