Arista Networks recognized by Gartner as a Leader in its 2017 Magic Quadrant for Data Center Networking for the third consecutive year!

Arista Networks, based in Santa Clara, California, is focused exclusively on data center networking and continues to grow above market rates, reaching a 9.8% revenue market share in 2016. Its Extensible Operating System (EOS) software is highly programmable and can be integrated with nearly all third-party cloud management and orchestration infrastructures. Arista’s CloudVision provides a central point of management, facilitating integration with third-party controllers (including VMware NSX). The vendor’s hardware strategy is based on leveraging merchant silicon from multiple suppliers and thus its focus is primarily on software and management, although Arista has shown an ability to deliver optimized merchant silicon-based products. Over the past year, Arista introduced support for data center interconnect (DCI) through the R-Series and announced containerized EOS for disaggregated use cases that use third-party hardware. The vendor also delivered more streaming telemetry capabilities, to improve visibility of network performance. All enterprises should consider Arista, particularly large organizations with advanced requirements that need flexible and programmable solutions. The resale partnership with HPE will help Arista increase global market coverage.

STRENGTHS
  • Arista offers a flexible solution that can integrate with a wide range of third-party software orchestration and SDN products, through open interfaces and programmability.
  • Arista provides high-performance and very scalable solutions, with deep buffers, large address tables and low latency.
  • CloudVision provides networkwide centralized state (NetDB), including telemetry and application visibility capabilities, along with extensible APIs and a software development kit (SDK).
  • Arista offers a portfolio of products with different form factors, including some large fixed configuration switches, enabling the implementation of high-performance, very scalable and rightsized solutions for every environment.
CAUTIONS
  • Geographic coverage has improved in 2016 and Arista now has an installed base in 70 countries, but its main presence remains with large customers in North America and Western Europe, so enterprise clients should assess the level of local support.
  • Arista does not provide interfaces for converged storage networks where FC (or FCoE) is a requirement, so it is suitable for environments that use IP storage or plan to maintain separate SANs.
  • Arista is focused only on data center solutions, which limits its ability to extend its architectural capabilities to campus and WAN networking only through partnerships (for example, with HPE).
  • An ongoing legal dispute with Cisco has been a distraction for Arista management; it led to longer lead times in delivering products. The import ban in the U.S. that was temporarily introduced and then lifted represented an increased level of perceived risk for some potential customers (see Note 1).
