Frequently Asked Questions

What is the difference between 7050CX3 and 7060CX2?

Both are 32-port 100GbE QSFP28 switches. The 7050CX3 is optimized for spine/aggregation with a balanced feature set, while the 7060CX2 offers additional uplink ports for higher-density spine deployments. Verify your specific requirements against Arista's datasheet.

What does the -R suffix indicate?

The -R suffix indicates rear-to-front airflow — air enters from the rear and exits from the front. This is suitable for hot aisle containment where the rear faces the hot aisle.

The Arista DCS-7050CX3-32C-R delivers 32-port 100GbE QSFP28 Layer 3 switching with rear-to-front airflow and Arista EOS — a high-performance data center spine switch for VXLAN/EVPN spine-leaf fabrics with automation and streaming telemetry.
