What is the switching capacity and port configuration of DCS-7170-64C-F?

The Arista DCS-7170-64C-F offers 12.8Tbps full-duplex switching capacity with 64x QSFP28 ports supporting 100GbE natively or breakout to 4x25GbE/10GbE. This non-blocking architecture delivers 10.24Bpps forwarding, ideal for spine roles in 100G leaf-spine fabrics handling east-west traffic at wire speed.

What latency performance does this switch achieve?

Port-to-port latency is under 400ns at 100GbE line rate with cut-through switching and AOS optimizations. This ultra-low latency suits high-frequency trading platforms, NVMe-oF storage fabrics, and RDMA over Converged Ethernet for AI training clusters requiring minimal delay.

Does it support advanced networking features like VXLAN and EVPN?

Yes, EOS natively supports VXLAN routing, EVPN control plane for L2/L3 VPNs, and MLAG for multi-chassis redundancy. CloudVision provides intent-based management, telemetry, and zero-touch provisioning for large-scale deployments.

What power consumption and airflow options are available?

Typical power draw is 850W at full load with 2.3W/Gbps efficiency. The -F variant features front-to-back airflow with redundant hot-swappable PSUs and fans, ensuring N+1 reliability in high-density 42U racks.

Is it suitable for RoCEv2 deployments in HPC?

Yes, it supports RoCEv2 with PFC, ECN, and DCB for lossless fabrics. 100G speeds and deep buffers prevent packet loss in GPU interconnects for HPC simulations and AI model training at petabyte scale.

What management and monitoring capabilities does EOS offer?

EOS includes eAPI for RESTCONF, gNMI streaming telemetry, and DANZ monitoring for tap aggregation. CloudVision orchestrates configuration across thousands of switches with real-time state synchronization and predictive analytics.
