More Information

Designed for IP storage, Content Delivery, and leaf and spine networks, the Arista 7020R Series fixed-configuration switches combine dynamic and deep buffering for lossless forwarding with high density, large table sizes, and comprehensive L2 and L3 features.

Ultra deep buffers and VOQ provide lossless performance in demanding environments where congestion and large flows are present such as in Big Data environments or Media and Entertainment. The non blocking architecture improves performance of bandwidth-intensive applications found in High Performance Storage or streaming video.



  • Dynamic deep buffers solve 1GbE and 10GbE speed mismatches in High Performance Computing and Oil and Gas Exploration Systems due to TCP incast

  • Virtual Output Queue (VOQ) eliminates head of line blocking and virtually eliminates packet drops due to network congestion

  • Arista FlexRoute™ and EOS NetDB™ for large scale routing with high density and low power

  • EOS Open Programmability and comprehensive Advanced Traffic Control, Provisioning and Monitoring features

  • High availability and power efficient, purpose built for for modern data centers


  • Compact 24 or 32 port 10G solution with dedicated 100G QSFP uplinks for lower density server/storage racks, edge compute and hyper-converged infrastructure

  • High performance solution with non-blocking 48 100/1000 Mbps (RJ-45) & six 1/10GbE uplinks (SFP+) for top of rack

  • Wire speed layer 2/3 switching up to 1.04 Tbps and 300 Mpps of throughput

  • 3GB packet buffer for lossless forwarding

  • Consistent architecture to 7280R Series for common operations, certification and sparing

  • 200 Gigabits of interconnect capacity from leaf to the spine


  • Up to 256K MAC entries

  • Up to 80K IPv4 and IPv6 Host Routes
