In this video, we go into how the Dell EMC PowerEdge R7525 leverages the unique capabilities of the AMD EPYC 7002 “Rome” series (and soon EPYC 7003 “Milan”) to provide either 128x or 160x PCIe Gen4 lanes in a single dual-socket server. This is an awesome design with a ton of flexibility and we are showing here how it works since Dell’s marketing department has not pushed this capability.
