N3K-C3172TQ-10GT Use Case
Scalable Leaf-Spine Aggregation with N3K-C3172TQ-10GT Nexus 3172T
In a 1,500-node enterprise data center, IT teams deploy the N3K-C3172TQ-10GT Nexus 3172T as top-of-rack leaf switches: 48×1/10GBase-T ports connect blade and rack servers, while six QSFP+ ports aggregate traffic into a 40GbE spine. Outcome: 4:1 oversubscription improvement, sub-50µs latency for east-west traffic, unified Cisco NX-OS automation for lifecycle management, and 35% lower Cost-per-Gigabit compared to legacy 1G/10G fabrics.
Ultra-Low-Latency AI/ML GPU Cluster Interconnect
A financial services firm accelerates high-frequency trading simulations by linking 200 GPU servers via the N3K-C3172TQ-10GT: 1/10GBase-T ports provide hot-swappable connectivity to on-premises compute nodes, and six 40GbE QSFP+ uplinks form a low-latency spine. Outcome: sub-3µs hop latency, 20% faster model convergence, seamless integration with Cisco ACI for policy-driven segmentation, and predictable performance under peak loads.
High-Performance Multi-Tenant Colocation Access Switching
A global colocation provider standardizes on the Nexus 3172T (N3K-C3172TQ-10GT) to offer customers premium port services: 48×1/10GBase-T front-panel ports deliver flexible 1GbE and 10GbE access, while six QSFP+ uplinks tie into a redundant core. Outcome: 99.99% SLA compliance, on-demand port scaling via Cisco DNA Center, streamlined billing with per-tenant QoS, and 30% reduction in rack-space power footprint.
