Cisco Nexus One
The network that works for you
Unify silicon, systems, optics, and software across all workloads—from traditional enterprise to AI-scale data centers—with a single, consistent operating model.
Unified data center networking for the AI era
Cisco Nexus One is a comprehensive data center networking foundation that spans silicon, systems, optics, software, and operating models. It delivers a consistent fabric experience across Cisco NX-OS, ACI, and SONiC—all managed from Cisco Nexus Dashboard—so organizations can deploy AI workloads without disrupting business operations or replacing existing infrastructure.
One platform. Every workload. Total flexibility.
Nexus One unifies silicon, systems, optics, and software across all workloads. Whether you are running traditional enterprise applications, cloud-native services, or massive AI training clusters, Nexus One provides a consistent operational experience managed from a single pane of glass through Cisco Nexus Dashboard.
Silicon One Powered
Purpose-built programmable ASICs including the G300 at 102.4 Tbps and P200 for scale-across, optimized for AI workloads and total cost of ownership.
Flexible OS Choice
Run Cisco NX-OS, ACI, or SONiC on the same N9000 systems. Protect investments and choose the operational approach that fits your business best.
Nexus Dashboard
Provision, configure, and operate from a single management plane with unified analytics, automation, assurance, and visibility across all fabrics.
Zero-Trust Security
Hardware root of trust on every port, quantum-resilient line-rate encryption, and real-time kernel-level mitigations with Cisco Live Protect enforcement.
Key capabilities delivered by Cisco Nexus One
Microsegmentation & Macrosegmentation
Flexible zero-trust networking models with granular microsegmentation and macrosegmentation policies that protect workloads in single-site and multi-site environments.
L4–L7 Service Insertion
Advanced Layer 4 through Layer 7 service insertion across single-site and multi-site deployments, enabling seamless integration of firewalls, load balancers, and other services.
Standards-Based Interoperability
RFC standards-based VXLAN EVPN fabric interoperability ensures openness across third-party networks, fostering multi-vendor integration without compromising functionality.
Infrastructure as Code
Native support for Ansible and Terraform enables responsive, efficient operating models for at-scale deployments with repeatable, version-controlled configurations.
Container Networking
Seamless integration with Kubernetes environments through Cisco Isovalent and Cilium, providing deep visibility into service IPs and traffic patterns across cloud-native workloads.
Turnkey Automation
Automated provisioning, configuration, and day-2 operations from Nexus Dashboard reduce complexity and accelerate time to value for data center deployments of any scale.
AI-Ready Infrastructure
Scale-out and scale-across for the AI era
Scale-out networking powered by Silicon One G300 delivers 102.4 Tbps switching with 64 ports of 1.6T OSFP connectivity. The fully shared 252MB packet buffer absorbs traffic bursts to prevent performance dips, delivering up to 2.5x increased burst absorption and a 28% reduction in job completion time.
Scale-across networking powered by Silicon One P200 enables deployment across geographic regions and sovereign clouds with 64 ports of 800G, quantum-safe line-rate encryption, and deep buffers optimized for universal spine use cases.
Open, integrated, and extensible
Nexus One supports multiple silicon options including Cisco Silicon One and NVIDIA Spectrum-X Ethernet switch silicon across N9000 switches. Combined with native Splunk integration in Nexus Dashboard for unified analytics and federated search, Nexus One delivers a complete operational experience without data duplication.
