Arista 7800R3 Series Introduction
Combining high density 100G and 400G with low latency and wire speed performance the Arista 7800R3 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 delivers a highly scalable and power efficient system optimized for modern datacenter and telco clouds.
The Arista 7800R3 Series FlexRoute engine provides the flexible scalability to support deployment as a routing platform with Internet scale routing. All Arista 7800R3 Series support FlexRoute™ engines providing the scalability to support deployment as a routing platform with Internet scale. The 7800R3 Series Accelerated sFlow feature samples and processes flow samples at line rate. The 7800R3K Series support a series of flexible profiles that leverage common resources for different network roles including up to 5M IP routes. Algorithmic ACLs enable more flexible and scalable solutions for access control, policy based forwarding and network telemetry, available on the Arista 7800R3, 7800R3A, 7800R3K and 7800R3AK series.
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.

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.
