In a high-density enterprise data center deploying a spine-leaf topology, the Cisco Nexus 31108PC-V leverages 48 SFP+ 10 Gbps server links and six QSFP28 40/100 Gbps uplinks to spine switches. This fabric delivers non-blocking 1.92 Tbps throughput, sub-500 ns latency, and automated NX-OS programmability for seamless east-west traffic. Benefit: Simplifies architecture, scales to thousands of servers, and ensures predictable high-performance at enterprise scale.
In a global VDI deployment supporting 5,000+ concurrent sessions, the Nexus 31108PC-V provides 48 SFP+ ports to hypervisor hosts and six 100 Gbps QSFP28 uplinks to core aggregation. Integrated QoS, VXLAN routing and per-flow telemetry guarantee low-latency delivery of voice, video and graphics. Outcome: Reduces desktop login times by up to 30%, maintains sub-millisecond response under peak load, and delivers consistent end-user experience.
In an AI/ML research lab with GPU-accelerated compute nodes and NVMe-oF storage, the Nexus 31108PC-V aggregates 10 Gbps storage SFP+ links and 100 Gbps QSFP28 inter-node links with RoCE support. The switch’s 1.44 Tbps fabric and sub-microsecond latency optimize distributed training and data shuffling. Outcome: Accelerates model training cycles by up to 40%, removes network bottlenecks, and enables massively parallel compute at scale.
