Arista DCS-7368X4-SC-R | 7368X4 Switch Card for Modular Chassis, 12.8 Tbps

Q: What is the DCS-7368X4-SC-R and how does it differ from the SC-F model?
A: The DCS-7368X4-SC-R is the switch card for the Arista 7368X4 modular chassis with rear-to-front airflow. The -R suffix indicates rear-to-front airflow, while the -F model provides front-to-rear airflow. Both deliver identical performance; choose based on your data centre cooling architecture.

Q: Can I use this switch card without interface modules?
A: The DCS-7368X4-SC-R requires compatible line cards (interface modules) to provide network connectivity. The switch card connects to up to 8 I/O module slots in the 7368X chassis, supporting various 100G, 200G, and 400G interface modules for flexible port configurations.

Q: What deployment scenarios is the 7368X4 switch card suited for?
A: The 7368X4-SC-R is designed for high-density data centre deployments as both leaf and spine switches in modern large-scale networks, including hyperscale cloud environments, serverless compute, big data farms, and machine learning clusters requiring high throughput and low latency.

Q: Does this switch card require a separate supervisor module?
A: Yes, the 7368X4 chassis requires a separate supervisor module that runs Arista EOS. Complete bundles typically include the chassis, power supplies, supervisor module, the X4-SC switch card, and fans.

Q: What advanced features does the 7368X4-SC support?
A: The switch card supports advanced traffic management including VXLAN, EVPN, MPLS, advanced multipathing for congestion management, LANZ and sFlow monitoring, hitless speed changes, and flow-aware detection for optimizing large-flow handling in demanding environments.
