Cisco N3K-C31108PC-V 48-Port 10G Data Center Switch

Brand:

The Cisco N3K-C31108PC-V is a high-density Nexus 3100 Series switch designed for modern data centers requiring low latency, scalable 10GbE connectivity, and high-speed 100GbE uplinks. Ideal for virtualization, cloud infrastructure, enterprise workloads, and spine-leaf architectures.

OVERVIEW

  • The Cisco N3K-C31108PC-V is a high-performance data center Ethernet switch built for organizations deploying cloud, virtualization, storage, and high-density compute environments. Featuring 48 SFP+ 10GbE ports and 6 high-speed 100GbE QSFP28 uplinks, it enables scalable server access while supporting rapid east-west traffic flows across modern data center fabrics.
  • Its low-latency architecture and wire-speed Layer 2/Layer 3 capabilities make it particularly valuable for enterprise data centers, managed service providers, cloud operators, and digital transformation initiatives. Compared to lower-density Nexus models, it offers a larger uplink capacity, greater aggregation flexibility, and enhanced scalability for spine-leaf deployments. The combination of compact 1RU design, redundant hot-swappable components, and VXLAN support helps organizations modernize infrastructure while protecting long-term investment and simplifying future expansion.
