Description

A dense 1U data center switch with 32x100GbE QSFP28 ports delivering true line‑rate L2/L3, ultra‑low latency, and hardware VXLAN/EVPN for scalable leaf/spine fabrics. Powered by Cumulus Linux for Linux-native operations, automation, and open networking. Port-to-chassis rear (P2C) airflow matches cold-aisle to hot-aisle deployments; dual hot-swap PSUs and N+1 fans ensure high availability. Ideal for leaf or spine roles with flexible breakout to 4x25G or 2x50G per port.

FAQs

Q: What airflow direction does this model use?
A: This variant uses P2C (port-to-rear) airflow to align with front-cold to rear-hot aisle cooling.

Q: Can I break out 100G ports to lower speeds?
A: Yes. Each QSFP28 can break out to 4x25G or 2x50G with the appropriate DAC/AOC or breakout fiber assemblies.

Q: What software is included?
A: It runs Cumulus Linux, enabling Linux-native operations, automation tooling (e.g., Ansible), and NCLU.

Q: Is this switch suitable for EVPN-VXLAN fabrics?
A: Yes. It supports hardware-accelerated VXLAN routing and EVPN control plane for leaf/spine deployments.

Q: Which optics and cables are supported?
A: QSFP28 transceivers (SR4/LR4/PSM4/CWDM4), DACs, and AOCs are supported; use appropriate breakout cables for 25G/50G.
