WHITE PAPER Real-Time Defense Systems Response Will Require PCIe 5.0 mrcy.com 2 mrcy.com 2 Today's modern defense systems exploit massive volumes of data to provide warfighters with more accurate, complete intel. Examples include advanced radar object detection and AI-driven threat identification. Solving bandwidth challenges at the system interconnect helps ensure mission success. Commercial semiconductor innovators are continuously developing new capabilities in silicon that defense system designers leverage to build open architecture-based processing solutions. When intelligently packaged for reliable deployment at the edge, the latest data center technologies can advance mission capabilities for the defense and aerospace sector. This paper examines the critically important interconnect technology and ecosystem built around Peripheral Component Interconnect Express (PCIe) standards and specifically, how the emerging PCIe 5.0 protocol benefits a new generation of rugged, deployable application platforms. Gen 5.0 doubles the bandwidth over the Gen 4.0 spec, which similarly doubled bandwidth over ubiquitous Gen 3.0 devices, and is an integral part of the latest devices from industry giants Intel® and NVIDIA. THE CURRENT NEED FOR MORE INTER-COMPONENT BANDWIDTH The nature of modern defense systems makes interconnect bandwidth increasingly critical to overall system performance. Field-deployed servers receive inputs from multiple types of sensor systems, including radar, lidar, visual imagery, EO/IR and EW. They also need to access stored data for comparison and analysis purposes; for example, identifying artifacts in a current image that were not present in yesterday 's image. Each sensor interface is a data path that must be able to keep pace with the data source. Then, to process those data streams, the server will typically employ multiple components of various types – CPUs, GPUs, FPGAs and DSPs – with interactions and data movement between them. Moving data quickly from one component to the next is critical to overall server performance. At a higher level, deployed servers must communicate with each other and with displays that form the human interface. RES X08 RUGGED RACK SERVERS These latest-gen rugged rack servers optimize the latest PCIe 5.0 compute, memory, storage and networking to eliminate bottlenecks, support hybrid computing architectures and drastically speed compute-intensive applications like sensor processing and artificial intelligence (AI), all in a smaller or equivalent form factor. RES X08 servers integrate the latest commercial technologies from Intel and NVIDIA including data center-class 4th gen Intel Xeon Scalable processors (formerly Sapphire Rapids), low-latency PCIe 5.0 fabrics, NVIDIA H100 GPUs, high-speed DDR5 memory and Compute Express Link (CXL) to infinitely scale system memory.
