OpenNebula Validated as an Orchestration Platform Integrated with NVIDIA Spectrum-X Ethernet Networking
OpenNebula Validated with NVIDIA Spectrum-X
Spectrum-X Ethernet is designed specifically for AI-scale networking, where traditional data center networks become a bottleneck. AI workloads—especially large-scale training and multi-tenant inference—are extremely sensitive to latency, congestion, and jitter. OpenNebula now integrates natively with NVIDIA Spectrum-X Ethernet to deliver a production-ready, software-defined cloud platform optimized for AI workloads. It enables secure, end-to-end multi-tenancy across compute, GPU, and network layers on a shared Spectrum-X Ethernet fabric, with direct GPU and SuperNIC passthrough to ensure predictable performance and strong isolation.
The integration is fully automated, with OpenNebula orchestrating tenant provisioning, network configuration, and device attachment through Spectrum-X Ethernet, reducing operational complexity and risk. The OpenNebula control plane is fully operational on NVIDIA Air, providing a simplified and cost-effective environment for testing, integration, and validation at scale. Customers can explore OpenNebula hands-on, evaluate its integration with Spectrum-X Ethernet, and leverage advanced simulations, automation workflows, and configuration rendering—making NVIDIA Air a practical platform for assessment and large-scale AI Factory and AI Gigafactory proof points.
“Through our collaboration with NVIDIA, we are extending OpenNebula to support the networking and performance requirements of modern AI infrastructures,” said Ignacio M. Llorente, CEO of OpenNebula Systems. “This integration allows customers to manage multi-tenant AI environments where NVIDIA Grace Blackwell and NVIDIA Grace Blackwell Ultra compute and Spectrum-X Ethernet networking are tightly orchestrated and optimized as a single platform.”
“OpenNebula’s integration with NVIDIA Spectrum-X Ethernet brings cloud-native agility to the AI Factory, enabling customers to orchestrate multi-tenant accelerated infrastructure with maximum performance and predictability,” said Amit Katz, VP of Networking at NVIDIA. “NVIDIA Air enables OpenNebula and our ecosystem partners to validate and simulate large-scale AI Factory deployments, giving customers a powerful environment to evaluate and accelerate their AI cloud strategies.”
The validation of OpenNebula with NVIDIA Spectrum-X Ethernet represents a significant step forward in delivering secure, high-performance, AI-ready cloud infrastructure for enterprise and service providers across Europe, particularly for large-scale AI Factories and AI Gigafactories. This integration enables high-performance segmentation of infrastructure, allowing multiple tenants to operate efficiently and securely on shared AI platforms.
