Description

The Arista DCS-7050X4-48Y-4DF-F is a high-performance 1RU data center switch designed for modern leaf-spine architectures. It delivers 5.6 Tbps of non-blocking throughput with 48x 25GbE SFP25 ports for server connectivity and 4x 400GbE QSFP-DD uplinks for spine interconnects. With 900 nanosecond cut-through latency, 82MB shared packet buffer with dynamic allocation, and comprehensive Layer 2/3 feature set including VXLAN, EVPN, and 128-way ECMP, this switch is optimized for cloud-scale data centers, AI/ML workloads, and high-density virtualization environments. Front-to-rear airflow design ensures efficient rack cooling.

Features

Wire-speed Layer 2 and Layer 3 forwarding with hardware-based packet processing
- Advanced routing protocols: BGP, MP-BGP, OSPF, OSPFv3, IS-IS, VRF-Lite
- VXLAN and EVPN support for network overlay and multi-tenancy
- MLAG (Multi-Chassis Link Aggregation) for active/active redundancy

FAQs

Q: What speeds do the SFP25 ports support?
A: Each of the 48 SFP25 ports supports 25GbE, 10GbE, and 1GbE speeds with auto-negotiation, providing backward compatibility with legacy server NICs and flexibility for mixed-speed deployments.

Q: Can the QSFP-DD uplinks be broken out into multiple ports?
A: Yes, each 400G QSFP-DD uplink can be broken out into 2x 200G, 4x 100G, 8x 50G, or 4x 40G ports using appropriate breakout cables and optics, expanding connectivity options up to 72 total logical interfaces.

Q: What is the difference between the -F and -R model suffixes?
A: The -F suffix indicates front-to-rear (forward) airflow, while the -R suffix indicates rear-to-front (reverse) airflow. This allows for flexible hot-aisle/cold-aisle data center rack configurations. Both models are electrically identical.

Q: Does this switch support VXLAN and EVPN for overlay networks?
A: Yes, the DCS-7050X4-48Y-4DF-F fully supports VXLAN encapsulation and EVPN control plane for multi-tenant overlay fabrics, making it ideal for modern cloud-scale data center deployments with network virtualization requirements.

Q: What high availability features are included?
A: The switch includes dual redundant hot-swappable AC power supplies, N+1 hot-swappable fans, MLAG for active/active multi-chassis redundancy, 128-way ECMP for load balancing, and Arista's Stateful Fault Repair and Smart System Upgrade capabilities for hitless maintenance.
