FAQs

Q: What port breakout options does the DCS-7050CX3-32S-D-R support?
A: Each QSFP100 port can be flexibly configured for 100GbE, 40GbE, 4x25GbE, 4x10GbE, or 2x50GbE modes, allowing up to 128 lower-speed ports when fully broken out. This flexibility enables seamless migration from legacy 10G/40G environments to modern 100G architectures.

Q: What does the 'D' in the model number signify?
A: The 'D' designates expanded memory and SSD configuration, providing enhanced system resources for advanced features, larger routing tables, and improved performance in demanding applications requiring additional memory and persistent storage capabilities.

Q: Is this switch suitable for leaf-spine data center topologies?
A: Yes, the DCS-7050CX3-32S-D-R is specifically designed for modern leaf-spine architectures. Its 6.4Tbps capacity, ultra-low 800ns latency, and deep packet buffers make it ideal for handling high-volume east-west traffic in cloud, enterprise, and high-performance computing environments.

Q: What airflow direction does the -R suffix indicate?
A: The '-R' suffix indicates rear-to-front (back-to-front) airflow, which is essential for hot-aisle/cold-aisle data center cooling designs. This ensures proper air circulation in densely packed rack environments with optimal thermal management.

Q: Does this switch support VXLAN and EVPN for network virtualization?
A: Yes, running Arista EOS, the DCS-7050CX3-32S-D-R fully supports VXLAN and EVPN for scalable multi-tenant network virtualization, overlay networks, and seamless VM mobility across modern data center fabrics.
