Arrcus Harnesses NVIDIA BlueField-4 to Power Gigascale AI Factories with Superior Network Performance and Efficiency

ArcOS running natively on NVIDIA BlueField-4 offloads and accelerates network and security functions for AI Clouds

SAN JOSE, Cali​f​.--(BUSINESS WIRE)--Arrcus, the hyperscale networking software company and a leader in core, edge, and multi-cloud routing and switching infrastructure, today announced support for the newly announced NVIDIA BlueField-4 platform, unveiled at GTC Washington, D.C. Designed to meet the demands of gigascale AI factories, the combination of Arrcus ArcOS® and NVIDIA BlueField-4 DPU will deliver new levels of acceleration, efficiency, and security for AI training, inference, and cloud-scale workloads.

BlueField-4 introduces 6x the compute power of BlueField-3 and 800 Gb/s networking speeds, unlocking powerful architectural, performance, and scale benefits while maintaining backwards compatibility. The platform integrates the NVIDIA Grace CPU and NVIDIA ConnectX-9 networking, providing advanced infrastructure acceleration and cybersecurity.

ArcOS Advantage

Arrcus ArcOS is built to run natively on NVIDIA BlueField-4, enabling customers to offload resource-intensive network functions including IPSec, NAT, Routing, EVPN/VXLAN, and ACLs. This offload capability increases throughput and efficiency, freeing up CPU cycles for AI workloads while ensuring secure multi-tenant connectivity and high-performance fabric orchestration.

Together, ArcOS and BlueField-4:

• Deliver accelerated performance across AI fabrics for training and inference workloads
• Extend AI fabric visibility, automation, and secure connectivity
• Open new monetization opportunities for NeoClouds, including Inference-as-a-Service
• Enable composable, cloud-ready infrastructure with NVIDIA DOCA microservices that deliver networking, data acceleration, and cybersecurity at scale
• Empower NeoCloud providers to unlock new monetization models, including Inference-as-a-Service, by delivering a highly efficient and optimized network fabric purpose-built for training and inference at gigascale

Together, Arrcus and NVIDIA are redefining the foundation of gigascale AI infrastructure. By pairing the flexibility of ArcOS with the acceleration of BlueField-4, customers gain a secure, high-performance fabric designed to scale effortlessly. This collaboration not only addresses today’s AI networking challenges but also lays the groundwork for future innovation in distributed AI, training, inference, and AI-as-a-Service.
