WHITE PAPER Real-Time Defense Systems Response Will Require PCIe 5.0 mrcy.com 5 THE EMERGING GEN 5.0 ECOSYSTEM It is this Gen 5.0 ecosystem of devices that will enable the next generation of high-performance servers for both commercial data centers and deployed defense applications. Intel - Intel Xeon Scalable Processors, formerly codenamed Sapphire Rapids, support leading industry standard technologies, including PCIe 5.0 as well as Compute Express Link™ (CXL) 1.1 to expand memory using PCIe slots. At 64 GB/s, Xeon Scalable PCIe gen-5 bandwidth not only helps today 's applications run faster, it also enables new applications in artificial intelligence (AI)/machine learning (ML) and cloud computing. With AI permeating more and more workloads, Intel has committed to deliver a 30x total AI performance gain through hardware and software optimizations for AI workloads. NVIDIA – NVIDIA is implementing PCIe 5.0 interconnects in its latest generations of both GPUs, DPUs and network interface modules. ▪ GPUs: The new NVIDIA H100 Tensor Core GPU has 32 lanes of PCIe 5.0 communications for 128 GB/s of data bandwidth. The H100 also delivers a huge leap in general purpose GPU (GPGPU) compute performance over the previous generation A100 GPU; fast Fourier transform (FFT) execution is six times faster for HPC applications, while AI apps are accelerated by factors ranging from nine to thirty. ▪ DPUs: In a complementary product line, the recently announced NVIDIA BlueField®-3 DPU has the same 32 lanes of PCIe 5.0 to drive 128 GB/s of bandwidth, so NVIDIA GPUs and DPUs can be configured together without bottlenecks. The BlueField-3 also has a PCIe switch supporting up to 16 downstream ports. The third- generation BlueField-3 delivers a five-times higher SPECINT score than the previous BlueField-2 device. ▪ Networking: Using technology acquired via its purchase of Mellanox, NVIDIA is also shipping the ConnectX®-7 SmartNIC, which delivers 100 GbE, 200 GbE, and 400 GbE Ethernet networking with a PCIe 5.0 x16/x32 interface. Other vendors – Intel and NVIDIA are not the only vendors bringing Gen 5.0 products to market. Astera Labs, Broadcom and AMD are just a few of the other companies building Gen 5.0 support into their newest solutions. DEPLOYABLE GEN 5.0 SERVERS FROM MERCURY SYSTEMS Mercury 's lightweight and compact rugged rack servers employ cutting-edge commercial technology, including Intel processors, NVIDIA GPUs, PCIe 5.0 and 200–400 Gb Ethernet networking, to tackle the most challenging workloads in the most remote environments – where the mission is critical and the cost of failure is high. Mercury has expanded its rugged server lines, with capabilities beyond the PCIe 4.0 architectures offered in RES X07 Intel- based rack mount servers and the RDP B02 NVIDIA GPU/ DPU-based server line, adding a new generation with a new generation of deployable RES X08 servers that support double the interconnect bandwidth. These will be based on PCIe 5.0 and exploit the powerful capabilities of Intel's third generation of Xeon Scalable Processors, NVIDIA's H100 Tensor Core GPUs, NVIDIA's ConnectX-7 NICs, and NVIDIA BlueField-3 DPUs. The new servers will deliver advanced data center-caliber performance to the tactical edge, eliminating latency bottlenecks and enabling compute- intensive applications to operate with real-time response. RES X08 servers incorporate the latest commercial technologies, ruggedized for the harshest environments.
