Arista DCS-7050SPX4-48D8-F | 7050X4 48-Port 100G DSFP Switch, 8x 400G QSFP-DD

Q: What port speeds does the DCS-7050SPX4-48D8-F support?
A: The 48 DSFP ports support flexible speeds of 100G, 50G, 25G, and 10G, while the 8 QSFP-DD uplink ports support 400G, 200G, 100G, and 40G. This allows seamless mixed-speed deployment and migration scenarios.

Q: What is the difference between the -F and -R models?
A: The -F suffix indicates front-to-rear (forward) airflow, while the -R model has rear-to-front (reverse) airflow. Both models are electrically identical with the same performance and features. Select based on your data center hot/cold aisle configuration.

Q: Does this switch support VXLAN and EVPN for overlay networks?
A: Yes, the DCS-7050SPX4-48D8-F fully supports VXLAN with EVPN for multi-tenant overlay fabrics, VRF for routing isolation, and comprehensive Layer 3 routing protocols including BGP, OSPF, and IS-IS.

Q: What is the switching capacity and latency of this switch?
A: The switch delivers 16 Tbps full-duplex non-blocking throughput with 2.78 Bpps forwarding rate. In cut-through mode, it maintains consistently low latency of 900 nanoseconds across all ports.

Q: Is this switch suitable for AI/ML and high-performance computing workloads?
A: Yes, the 7050SPX4 is optimized for 50G/100G PAM4-based server NIC connectivity and AI/ML training clusters. With 82MB shared buffer, dynamic load balancing, and 128-way ECMP, it handles bursty traffic and east-west flows efficiently.
