N3K-C31108PC-V-Ref Overview
N3K-C31108PC-V is the Nexus 31108PC-V, providing 48 SFP+ and 6 QSFP28 ports. The Cisco Nexus 3100-V switch platform is the latest addition to the industry’s widely deployed Cisco Nexus 3100 platform. The Cisco Nexus 3100-V platform consists of high-density, low-power-consumption, and low-latency fixed-configuration data center switches with line-rate Layer 2 and 3 features that support enterprise applications, service provider hosting, High-Performance Computing (HPC), and cloud computing environments. These switches support a wide range of port speeds with flexible combinations of 1/10/40/100-Gbps connectivity with improved port density and scalability in compact 1-rack-unit (1RU) form factors.
