NXM-X16C Use Case
Data Center Spine-Leaf Scaling for Hyperscale Workloads
Scenario: A cloud provider is experiencing exponential north-south traffic growth across its spine-leaf fabric. By deploying the NXM-X16C-Nexus 100G Line Expansion Module in Nexus 9500 series switches, operators gain sixteen additional QSFP28 100G uplinks in a single slot. Outcome: 2.56 Tbit/s of non-blocking bandwidth expansion, 50% higher port density per RU, and seamless scaling of compute and storage clusters with sub-microsecond latency—driving improved application performance and reduced congestion.
High-Performance AI/ML Cluster Interconnect
Scenario: An enterprise AI lab needs ultra-low latency and high-capacity links between GPU-accelerated servers for distributed training. Integrating the NXM-X16C into Nexus 9300 switches delivers 1.6 Tbit/s of bi-directional 100G connectivity across 16 ports. Outcome: 40% faster model convergence through optimized throughput, streamlined cable management with breakout optics support, and predictable end-to-end performance—enabling data scientists to reduce iteration time and speed AI innovation.
5G Mobile and Edge Aggregation for Service Providers
Scenario: A telecom operator is rolling out edge compute nodes to support 5G mobile backhaul and MEC services. Installing the NXM-X16C-Nexus 100G module in Nexus 9500 edge routers provides sixteen high-density 100G interfaces for cell-site aggregation. Outcome: Simplified architecture with higher port count per line card, 30% lower power per gigabit, and sub-1 ms latency—ensuring SLA-driven performance, expedited service rollouts, and reduced TCO for next-gen mobile services.
