What is the port configuration and speed flexibility of DCS-7050SX3-48YC8C-F?

Features 48x 1/10/25GbE SFP28 downlink ports and 8x 40/100GbE QSFP28 uplinks with breakout to 4x10/25G per port. Supports mixed 1G/10G/25G servers with auto-negotiation and flexible optics including multimode/singlemode transceivers for 100m to 10km reaches.

What switching performance does this Arista switch provide?

Delivers 4Tbps full-duplex switching capacity and 3.2 billion packets per second forwarding rate. Non-blocking architecture ensures wire-speed across all ports with <5us latency, ideal for high-throughput data center east-west traffic patterns.

Does it support network virtualization for cloud deployments?

Yes, Arista EOS provides VXLAN Layer 3 routing, EVPN control plane, and VARP anycast gateway. Supports up to 256K MAC addresses and 128K routes, enabling massive scale multi-tenancy without recabling.

What power and thermal specifications apply?

Max power draw 525W with dual 650W AC PSUs (1+1 redundant). Port-to-PSU airflow (F) with front-to-back cooling. Operates 0-40C with 700 CFM fans, supporting high-density 25/100G without thermal throttling.

Is it suitable for lossless Ethernet in storage fabrics?

Yes, supports RoCEv2 with PFC, ECN, and DCQCN for lossless transport. 16GB buffers absorb bursts in NVMe-oF and Ceph deployments, ensuring zero packet loss under congestion.

What management and monitoring capabilities are included?

EOS offers eAPI, gNMI, OpenConfig YANG models, and DANZ Network Telemetry with sFlow, mirror-anywhere, and tap aggregation. CloudVision integration provides zero-touch provisioning and AI analytics.

Product overview

The Arista DCS-7050SX3-48YC8C-F is a high-performance, fixed-configuration 1U data center switch from the 7050X3 series, optimized for modern cloud and enterprise infrastructures. It features 48x 25GbE SFP28 downlink ports for high-density server connectivity and 8x 100GbE QSFP28 uplink ports supporting breakout to 4x25G, providing flexible 25/100G scaling. With 4Tbps full-duplex switching capacity and 3.2Bpps forwarding rate, it ensures wire-speed, low-latency performance across all ports. Powered by Arista EOS, it supports advanced features like VXLAN routing, EVPN, MLAG for leaf-spine fabrics, RoCEv2 for storage fabrics, and DANZ monitoring for telemetry. Deep buffers up to 16GB handle microbursts in congested environments. Ideal for top-of-rack, spine, or aggregation roles in hyperscale data centers, service provider clouds, financial trading, and high-performance computing. Airflow is port-to-PSU (F) configuration with dual hot-swappable PSUs for redundancy. Field-proven reliability with <5us latency makes it a cornerstone for 25/100G network upgrades.
