The Cisco Nexus 93180YC-FX3 (N9K-C93180YC-FX3) is a high-performance, 1RU fixed-configuration data center switch belonging to the Nexus 9300-FX3 series. Built on Cisco Cloud Scale technology, it is purpose-built for modern leaf-spine architectures, supporting high-density 25G server connectivity and 100G uplinks. It operates in both NX-OS standalone mode and ACI (Application Centric Infrastructure) mode, making it ideal for cloud, virtualization, and high-performance computing (HPC) environments.
High-Density 25G/100G Connectivity
48 x 1/10/25G SFP28 downlink ports for line-rate server connections.
6 x 40/100G QSFP28 uplink ports for high-speed spine switch interconnection.
Non-blocking switching capacity: 3.6 Tbps.
Forwarding rate: 1.2 Bpps.
Ultra-low latency: < 1 microsecond (cut-through mode).
Robust Hardware & Scalability
16 GB DRAM / 16 GB flash memory for extensive routing tables and telemetry.
48 MB dynamic shared packet buffer to absorb traffic bursts.
