FAQs

Q: What deployment scenarios is the DCS-7050DX4-32S-R designed for?
A: This switch is ideal for high-performance data center leaf and spine architectures, supporting cloud computing, AI/ML workloads, high-frequency trading, and enterprise networks requiring scalable 400G density with flexible breakout to lower speeds.

Q: Can the 400G QSFP-DD ports be broken out to lower speeds?
A: Yes, each 400G QSFP-DD port supports flexible breakout configurations including 400G, 200G, 100G, 50G, 40G, 25G, and 10G modes, enabling up to 128 ports of 10G/25G or 64 ports of 200G using appropriate transceivers and breakout cables.

Q: Does this switch support Layer 3 routing and VXLAN?
A: Yes, the DCS-7050DX4-32S-R delivers wire-speed Layer 2 and Layer 3 forwarding with support for advanced routing protocols, single-pass VXLAN routing and bridging, ECMP up to 128-way, and dynamic load balancing for modern data center network segmentation.

Q: What are the power and cooling requirements?
A: The switch includes dual redundant hot-swappable 500W AC power supplies and features rear-to-front airflow (indicated by the -R suffix). It is designed for standard data center rack deployment with efficient cooling in port-side exhaust configurations.

Q: Is the switch compatible with Arista CloudVision management?
A: Yes, the DCS-7050DX4-32S-R fully integrates with Arista CloudVision for centralized network-wide automation, orchestration, telemetry, and workflow management, supporting Zero Touch Provisioning and programmable APIs for automated deployments.
