NVIDIA Spectrum-X is a new class of Ethernet networking for AI that can deliver 1.6x higher performance for AI communication than traditional Ethernet offerings. NVIDIA announced today that Dell Technologies, Hewlett Packard Enterprise (HPE), and Lenovo will be the first to integrate this technology into their server lineups to help enterprise customers accelerate generative AI workloads.
Generative AI is a branch of artificial intelligence that can create new content or data from existing data, such as images, text, audio, or video. Generative AI can enable applications such as natural language processing, computer vision, speech synthesis, data augmentation, and more.
However, generative AI also poses significant challenges for enterprise infrastructure, as it requires high-speed and low-latency network connectivity between servers, GPUs, and data sources. Traditional Ethernet networking can become a bottleneck for generative AI workloads, limiting their scalability and efficiency.
NVIDIA Spectrum-X: How It Works
NVIDIA Spectrum-X is a purpose-built solution for generative AI that combines three key components: the Spectrum-4 Ethernet switch, the BlueField-3 SuperNIC, and the acceleration software.
The Spectrum-4 Ethernet switch is the world’s first 51Tb/sec Ethernet switch for AI, providing high data throughput at scale and under load while minimizing network congestion for multi-tenant, AI cloud workloads. It also features intelligent, fine-tuned routing technology that enables maximum utilization of network infrastructure at all times.
The BlueField-3 SuperNIC is a new class of network accelerators for supercharging hyperscale AI workloads. It offers up to 400Gb/s RDMA over Converged Ethernet (RoCE) network connectivity between GPU servers and boosts performance for AI training and inference traffic on the east-west network inside the cluster.
It also enables secure, multi-tenant data center environments, ensuring deterministic and isolated performance between tenant jobs. The BlueField-3 SuperNIC has a power-efficient, half-height, half-length PCIe form factor that makes it ideal for enterprise-class servers.
The acceleration software powering Spectrum-X features NVIDIA software development kits such as Cumulus Linux, Pure SONiC, and NetQ, which together drive the platform’s breakthrough performance. It also includes the NVIDIA DOCA software framework, which is at the heart of BlueField.
NVIDIA Spectrum-X: What It Enables
NVIDIA Spectrum-X enables enterprises to leverage the power of generative AI to transform their businesses. It works seamlessly with NVIDIA Tensor Core GPUs, NVIDIA AI Enterprise software, and NVIDIA AI Workbench software to provide enterprises with the building blocks to create, test, and deploy generative AI models.
NVIDIA Tensor Core GPUs are the world’s most advanced GPUs for AI, delivering up to 20x faster performance than CPUs for AI workloads. NVIDIA AI Enterprise is a comprehensive software suite that provides frameworks, pre-trained models, and development tools for secure, stable and supported production AI. NVIDIA AI Workbench is a software tool that allows developers to quickly create, test, and customize pre-trained generative AI models on a PC or workstation, then scale them to virtually any data center or cloud.
NVIDIA Spectrum-X also powers the NVIDIA Israel-1 supercomputer, a reference architecture for next-generation AI systems. Israel-1 is a collaboration with Dell Technologies, using Dell PowerEdge XE9680 servers powered by the NVIDIA HGX H100 eight-GPU platform and BlueField-3 DPUs and SuperNICs with Spectrum-4 switches.
When It Will Be Available
NVIDIA Spectrum-X is expected to be available in the first quarter of next year. Dell, HPE, and Lenovo will be the first to offer new systems featuring the complete NVIDIA AI stack, including Spectrum-X, Tensor Core GPUs, AI Enterprise, and AI Workbench.
NVIDIA Spectrum-X is a game-changer for generative AI and accelerated computing. It offers enterprises a new class of Ethernet networking that can boost generative AI workloads and drive innovation across multiple industries.
