Arista 7280E Series Introduction

The Arista 7280E Series is a key component of the Arista 7000 Series portfolio of data center switches. The Arista 7280E series is a set of purpose built 10/40/100GbE 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 7280E capabilities address the requirements for modern networking and rich multimedia where content delivery require a lossless forwarding solution.

7280E Advantages

  • Industry first, standards-based 100G top of rack switch ideal for future proofing designs and high bandwidth needs such as in High Performance Storage or Content Delivery Networks (CDNs)
  • Ultra deep buffers in a 1RU form factor makes for an ideal top of rack switch where lossless performance and in-cast problems are expected such as in data analytics, IP storage and big data environments
  • Integrated SSD Storage allows for unique extensibility abilities and traffic monitoring for truly capable SDN
  • Wire speed VXLAN tagging support, extending the next generation of scalable data centers
  • Hardware assisted Precision Time Protocol enables accurate timing solutions across Ethernet based networks without costly investments in deploying 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
  • Balanced L2 and L3 table resources allow deployment flexibility in both large L2 and L3 environments with any-workload suitability
  • Network–wide virtualization platform for next generation cloud bursting with wire-speed VXLAN hardware-based Tunnel Endpoint (VTEP) termination.

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.

7280E Series Systems

The Arista 7280SE Series extends the Arista 1RU product portfolio, providing a combination of deep buffers, extensive features such as VXLAN and LANZ, and the industry’s first 100G Top of Rack switch built for storage networks, content delivery networks, and lossless spline/leaf datacenter designs.
