FAQs

Q: What is the difference between DSFP and SFP-DD ports?
A: DSFP (Dual Small Form Factor Pluggable) is optimized for PAM4-based 50G/100G server NIC connectivity and supports the same speed ranges as SFP-DD (100G/50G/25G/10G). The 7050SPX4 uses DSFP ports for server-facing connections, while the alternative 7050SDX4 model uses SFP-DD ports.

Q: Can this switch be used as a spine or leaf switch?
A: Yes, the DCS-7050SPX4-48D8-R is designed for both roles. It excels as a leaf switch with 48 server-facing DSFP ports and 8 × 400G QSFP-DD uplinks to spine switches, or can function as a spine switch for smaller fabrics. Its 16 Tbps throughput and 128-way ECMP make it ideal for modern leaf-spine architectures.

Q: What is the airflow direction and why does it matter?
A: The -R suffix indicates rear-to-front (reverse) airflow, where cool air enters from the rear and hot air exhausts from the front. This is critical for hot-aisle/cold-aisle data center designs. The front-to-rear variant is model DCS-7050SPX4-48D8-F. Choose airflow direction based on your rack cooling configuration.

Q: Does this switch support VXLAN and EVPN for overlay networks?
A: Yes, the 7050SPX4 fully supports VXLAN and EVPN for multi-tenant overlay fabrics. It also supports BGP, OSPF, IS-IS, MLAG, VARP, and other advanced Layer 2/3 protocols required for modern data center network architectures.

Q: What licensing is required for this switch?
A: The Arista 7050X4 Series runs Arista EOS (Extensible Operating System), which includes all Layer 2/3 features and automation capabilities without tiered licensing. Software updates and support are included with Arista Care service contracts. No separate feature licenses are required for core switching functionality.
