Introduction to BRKDCN-2980.pdf Documentation
This technical design guide outlines Cisco’s validated architecture principles for next-generation data center networks, focusing on high-density 400G deployments and multi-cloud integration strategies. Originally presented at Cisco Live 2025, the document serves as a reference architecture for implementing spine-leaf topologies with Cisco Nexus 9000 Series switches.
The 2025 edition introduces updated design considerations for AI/ML workloads and quantum-safe encryption implementations. Compatible with Cisco Nexus 9300-GX2 and 9800-CL platforms, this guide supports NX-OS 10.4(x) and ACI 6.2(x) software environments.
Key Technical Content
1. Architecture Validation
- 400G spine node oversubscription ratios for mixed HPC/virtualization workloads
- VXLAN BGP EVPN design patterns for Kubernetes container networking
2. Security Implementation
- Zero Trust segmentation models using ACI microsegmentation
- Hardware-based encrypted traffic analytics (ETA) configurations
3. Performance Optimization
- Adaptive buffering configurations for RoCEv2 traffic
- Deep packet inspection telemetry collection methods
4. Multi-Cloud Integration
- AWS Transit Gateway interconnect blueprints
- Azure Arc-enabled infrastructure monitoring templates
Compatibility Reference
| Supported Platforms | Minimum NX-OS Version | ACI Compatibility |
|---|---|---|
| Nexus 9336C-GX2 | 10.4(1) | 6.2(3) |
| Nexus 9808-CL | 10.4(2) | 6.2(4) |
| UCS X-Series | 5.2(1a) | N/A |
Important: Design assumptions based on Cisco 25G SerDes technology – verify QSFP-DD transceiver compatibility before implementation.
