Arista 7280R Series Introduction

The Arista 7280R Series are a key component of the Arista 7000 Series portfolio and consist of 7280R and 7280R2 products. The Arista 7280R Series is a set of purpose built 10/25/40/50/100GbE fixed configuration systems designed for the highest performance environments, where wire speed L2 and L3 forwarding are combined with advanced features for network virtualization, open monitoring and network analysis, resiliency and architectural flexibility. The 7280R Series capabilities address the requirements for modern networking and rich multimedia where content delivery require a lossless forwarding solution.

The Arista 7280R SeriesFlexRoute engine provides the flexible scalability to support deployment as a routing platform with Internet scale routing. Arista FlexRoute along with EOS NetDB enables innovation not natively available in merchant chipsets. The 7280R Series Accelerated sFlow features samples and processes flow samples into datagrams in dedicated engines. AlgoMatchTM, a unique Arista innovation to enable more flexible and scalable solutions for access control, policy based forwarding and network telemetry is available on the Arista 7280RA and 7280R2A series.

7280R Advantages

  • Standards-based high density 100G switch ideal for future proof designs and high bandwidth needs such as in High Performance Storage or Content Delivery Networks (CDNs)
  • Dynamic deep buffers in a fixed form factor makes for an ideal top of rack switch where lossless performance and in-cast problems are expected such as in data analytics and IP storage
  • Directly connected 25GbE, 40GbE and 50GbE attached storage systems, requiring high performance and predictable latency
  • Streaming network state for advanced analytics with CloudVision
  • Network–wide virtualization platform for next generation cloud bursting with wire-speed VXLAN routing
  • Hardware assisted PTP enables accurate timing solutions across Ethernet based networks without costly investment in separate timing networks
  • Unique monitoring and provisioning features – LANZ, DANZ, AEM, IEEE 1588, PTP, ZTP, VM Tracer, VXLAN, and eAPI
  • Comprehensive L2 and L3 feature set for open multi-vendor networks with no proprietary lock-in
  • Large scale L2 and L3 table resources allow deployment flexibility in both large L2 and L3 environments with any-workload suitability
  • NEBS compliance and DC power supplies designed for service provider environments

Arista EOS

Arista EOS is a modular switch operating system with a unique state sharing architecture that cleanly separates switch state from protocol processing and application logic. Built on top of a standard Linux kernel, all EOS processes run in their own protected memory space and exchange state through an in-memory database. This multi-process state sharing architecture provides the foundation for in-service-software updates and self-healing resiliency.
