The Cisco N3K-C31108PC-V is a Nexus 3100-V VXLAN-capable switch with 48x 1/10 Gigabit SFP+ ports and six 100 Gigabit QSFP28 uplinks (each also 40GB or 4x 10GB). It suits top-of-rack and aggregation roles in data center and campus networks. This unit is the back-to-front (port-side exhaust) airflow version: cooling air enters at the fan and power supply side and leaves at the port side. It runs Cisco NX-OS with the usual Nexus toolset for automation and monitoring.
Capacity is 2.16 Tbps with a 1.2 Bpps forwarding rate, a 16 MB shared packet buffer, and a 288,000-entry MAC address table. Latency runs approximately 650 ns nominal. The switch carries 16 GB DRAM and 64 GB SSD.
Fans and power supplies are hot-swappable and redundant, and every module in one chassis must share the same airflow direction. Fan choices are the NXA-FAN-30CFM-F (port-side exhaust) or NXA-FAN-30CFM-B (port-side intake). Power supply choices are the NXA-PAC-650W-PE AC and NXA-PDC-930W-PE DC (port-side exhaust) - NXA-PAC-650W-PI AC and NXA-PDC-930W-PI DC (port-side intake). Check the fitted fan and power supply part numbers against your row's airflow before racking the switch.
If you cable with copper, the Nexus 31108TC-V swaps the SFP+ ports for 10GBASE-T RJ45.
