Product overview

The Arista DCS-7050SX-72Q-F is a high-performance 1RU data center switch from the 7050X Series, featuring 48x 1/10GbE SFP+ ports and 6x 40GbE QSFP+ ports for wire-speed Layer 2/3 forwarding up to 1.44 Tbps. Equipped with a high-performance x86 CPU, 4GB system memory, and up to 16MB dynamic packet buffer, it supports 288K MAC entries, 144K IPv4 routes, 208K IPv4 host routes, and 4096 VLANs with Q-in-Q. Advanced routing includes OSPF, BGP, IS-IS, and 64-way ECMP. Layer 2 features encompass 802.1w RSTP, LACP, and multicast with IGMP snooping. Management capabilities include VXLAN, VM Tracer, OpenFlow, sFlow, live patching, and Stateful Fault Repair. Dual AC power supplies with front-to-rear airflow ensure reliability in datacenter environments. Operating from 0-40°C, it meets FCC, UL safety standards, ideal for scalable cloud infrastructure, leaf-spine topologies, and high-density 10/40GbE deployments requiring low latency under 550ns.
