Cisco Nexus 9636C-H2R 400G Spine Switch

The Cisco Nexus 9636C-H2R is a 36-port 400G Ethernet spine switch purpose-built for next-generation data center architectures. Each port supports QSFP-DD optics, delivering 14.4 Tbps of non-blocking throughput in a single 2RU form factor. The modular Nexus 9000 chassis design integrates deeply with NX-OS operating system, enabling hardware-based telemetry, segment routing, and advanced traffic management at line rate.

Optimized for high-performance computing and artificial intelligence workloads, the 9636C-H2R addresses the fabric demands of large-scale GPU cluster deployments and hyperscale distributed training environments. Its architectural efficiency reduces latency-sensitive east-west traffic bottlenecks inherent in traditional three-tier designs, while supporting deterministic latency requirements across heterogeneous compute resources.

The platform integrates in-service software upgrades (ISSU), redundant supervisors, and multi-chassis link aggregation capabilities, enabling carrier-grade resilience for mission-critical infrastructure. Native support for Open Network Install Environment (ONIE) and streaming telemetry via gRPC facilitates standards-based operational integration.

Ideal for

• AI/ML training clusters requiring high-bandwidth, low-latency interconnect for all-reduce operations across distributed GPU pools
• Hyperscale data center fabric spine layer consolidating multiple leaf switches under unified management
• High-performance computing (HPC) environments with tightly-coupled compute nodes demanding deterministic east-west throughput
• Cloud-native infrastructure supporting 400G leaf-to-spine architectures for container orchestration platforms
• Quantum computing resource centers requiring ultra-low latency and high predictability for qubit control systems
• Research institutions deploying large-scale scientific computing grids with bandwidth-intensive data movement
