Arista DCS-7060DX5-64S-R | 7060X5 64-Port 400G Switch, 25.6Tbps, 2RU

Q: What port speed configurations does the DCS-7060DX5-64S-R support?
A: All 64 QSFP-DD ports support flexible speeds including native 400GbE, breakout to 2x200GbE, or breakout to 4x100GbE per port. This allows up to 256x 100G interfaces, providing exceptional deployment flexibility for mixed-speed environments and migration scenarios.

Q: What does the -R suffix indicate in the model number?
A: The -R suffix denotes rear-to-front airflow (port-side exhaust) configuration. This airflow direction is designed for hot-aisle/cold-aisle data center deployments where cool air enters from the front ports and exhausts toward the rear power supplies.

Q: What software licensing does this switch require?
A: The base Arista EOS software is included with the hardware. Advanced routing features require the EOS Enhanced license for BGP, OSPF, and multicast. For VXLAN and BGP-EVPN, the EOS Flex-route Lite license is needed. CloudVision automation is available as an optional subscription.

Q: Is this switch suitable for AI/ML cluster deployments?
A: Yes, the 7060DX5-64S is specifically optimized for AI/ML workloads with ultra-low 825ns latency, deep 114MB buffers for burst absorption, and support for RDMA/RoCE with advanced congestion management. It's ideal for GPU cluster spine switches and high-performance computing fabrics requiring non-blocking throughput.

Q: What optics are compatible with the QSFP-DD ports?
A: The QSFP-DD ports support industry-standard 400G, 200G, 100G, 50G, 25G, and 10G optics including SR8, DR4, FR4, LR4, and passive/active copper DAC cables. Arista maintains a compatibility matrix at arista.com/en/products/transceivers-cables for specific optics and minimum EOS versions.
