N9K-C93108TC-FX Cisco Nexus 93108TC-FX Switch with 48x 10GBase-T and 6x 40/100G QSFP28 Uplinks
High-Density, Low-Latency 10G/100G Data Center Switch with Advanced Programmability and Cloud-Scale Performance
The Cisco Nexus 93108TC-FX (N9K-C93108TC-FX) is a high-performance, ultra-low-latency data center switch designed for modern Top-of-Rack (ToR) and Middle-of-Row (MoR) deployments. Built for scalable, software-defined data centers, it delivers high-density 10GBASE-T server connectivity combined with flexible 40G/100G uplinks, making it ideal for enterprise, cloud, and service provider environments.
This switch features 48 multi-speed 10GBASE-T ports supporting 100 Mbps, 1G, and 10G, enabling seamless migration from legacy copper networks to high-speed 10G infrastructures. Additionally, 6 QSFP28 uplink ports provide 100G connectivity with support for breakout modes including 4×10G, 4×25G, and 2×50G, offering exceptional flexibility for spine-leaf architectures.
With a switching capacity of up to 2.16 Tbps, forwarding rates up to 1.2 Bpps, and sub-microsecond latency, the Nexus 93108TC-FX delivers consistent, line-rate performance even under full load. A 40 MB shared buffer ensures excellent handling of bursty traffic and congestion, making it suitable for virtualization, storage, and high-performance computing workloads.
The switch runs Cisco NX-OS or can operate in Cisco ACI mode, supporting advanced data center networking features such as VXLAN with EVPN, deep telemetry, and full programmability through REST APIs, Python scripting, and P4 runtime. Enterprise-grade security is enhanced with MACsec encryption on uplink ports, while high availability is ensured through redundant hot-swappable power supplies and fans, along with In-Service Software Upgrade (ISSU) for minimal downtime.
Designed for operational efficiency, the Cisco Nexus 93108TC-FX supports front-to-back or back-to-front airflow, integrates seamlessly with Cisco DCNM and Cisco ACI, and fits into both leaf and spine roles in scalable data center fabrics.
