Arista 7500R Series Introduction

Combining high density 10/40 and 100GbE with low latency and wire speed performance the Arista 7500R Series are designed for large virtualized data centers, internet peering, cloud networks and mission critical environments. A deep buffer VoQ architecture with large routing tables in a compact design delivers a highly scalable and power efficient system.

The Arista 7500R Series FlexRoute Engine provides the flexible scalability to support deployment as a routing platform with Internet scale routing enabling innovation not natively available in merchant chipsets. With front-to-rear airflow, redundant and hot swappable supervisor, power, fabric and cooling modules the system is purpose built for high availability and continuous operations.

7500R Advantages

  • Support for over 2,300 10Gb and 25Gb Ethernet ports - 2304 x 10G / 25G, 576 x 40G / 100G Ethernet interfaces
  • Broad choice of compact to highly scalable chassis ranging from 16 slot to 4 slot systems
  • Seamless investment protection with 7500E line cards, fabric and supervisor
  • Streaming network state for advanced analytics with CloudVision
  • Unique monitoring and provisioning features – LANZ, DANZ, AEM, PTP, ZTP, VM Tracer, VXLAN, and eAPI
  • Comprehensive L2 and L3 feature set for open multi-vendor networks with no proprietary lock-in
  • Scalable L2 and L3 table resources allow deployment flexibility in both large L2 and L3 environments and internet peering with any workload suitability
  • AlgoMatchTM for flexible and scalable solutions for access control and network telemetry
  • Network–wide virtualization platform for next generation cloud bursting with wire-speed VXLAN routing
  • Directly connected 25GbE, 40GbE and 50GbE attached storage systems, requiring high performance and predictable latency
  • Performance optimized DCI solution with line rate encryption with MACSec and coherent optics for long haul connectivity

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.
