Arista 7280R Series Technical Specifications

The Arista 7280R series is a set of purpose built 10/25/40/50/100GbE fixed configuration 1RU and 2RU systems designed for the highest performance environments such as IP Storage, Content Delivery Networks, Data Center Interconnect and IP Peering. Wire speed L2 and L3 forwarding are combined with advanced features for network virtualization, open monitoring and network analysis, resiliency and architectural flexibility with deterministic performance. Deep packet buffers and large routing tables allow for Internet peering applications and the broad range of interfaces and density choice provides deployment flexibility.

The Arista 7280R Series FlexRoute™ engine provides the scalability to support deployment as a routing platform with Internet scale routing. Arista FlexRoute along with EOS NetDB™ enables innovations and convergence not natively available in merchant chipsets.

 

7280R Benefits

  • 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
