Andy Bechtolsheim and Jayshree Ullal discuss Arista Networks and Cloud Computing

7050 Series

Industry Leading Performance, Power-Efficiency, and High Availability

The Arista 7050 Series is a family of compact 1RU 10GbE and 40GbE wire speed L2 and L3 switches powered by the Arista Extensible Operating System (EOS). The 7050 Series provide the performance and scalability for big data, IP Storage applications and dense virtualization environments with low latency and high availability.

  • Performance: Up to 1.28 Tbps and 960 Mpps
  • Non-blocking wire speed forwarding at both L2 and L3
  • Density: 64 and 52 ports of 10Gb
  • Low latency: 800ns-1200ns
  • Lowest Power: less than 2W per port
  • Highest scale for L2, L3 and IP Multicast
  • 40 GbE QSFP+ uplinks and support for 1 GbE on all SFP+ ports
  • 50 GB SSD for data capture and on switch storage
  • Consistent binary software image shared across all Arista switches
