Arista 1G/10G Series Technical Reference Guide: 7010T & 7020R Series

Complete technical specification matrix and ordering guide for Arista high-density 1G RJ45 and 10G SFP+ data center and campus access switches.

Architecture: Compact 1RU power-efficient wire-speed Layer 2 and Layer 3 switches engineered for enterprise campus edge, high-density server rack management, and low-latency data center environments.
Deep Buffer Architecture: Arista 7020R Series features deep dynamic packet buffering to eliminate packet loss under heavy burst traffic conditions.
Power Efficiency: Ultra-low power consumption starting under 1W per port with energy-efficient IEEE 802.3az support on select models.
Hardware Redundancy: Dual hot-swappable AC/DC power supplies and N+1 hot-swappable fan modules for high availability.
Operating System: Powered by Arista EOS, providing continuous state sharing, advanced monitoring (LANZ, DANZ), Zero Touch Provisioning (ZTP), and robust VXLAN/L3 capabilities.
