Networking
The World’s Most Advanced Network Operating System
Arista Extensible Operating System (EOS®) is the core of Arista cloud networking solutions for next-generation data centers and cloud networks. Cloud architectures built with Arista EOS scale to hundreds of thousands of compute and storage nodes with management and provisioning capabilities that work at scale. Through its programmability, EOS enables a set of software applications that deliver workflow automation, high availability, unprecedented network visibility and analytics and rapid integration with a wide range of third-party applications for virtualization, management, automation and orchestration services.
Arista EOS is a fully programmable and highly modular, Linux-based network operation system, using familiar industry standard CLI and runs a single binary software image across the Arista switching family. Architected for resiliency and programmability, EOS has a unique multi-process state sharing architecture that separates state information and packet forwarding from protocol processing and application logic.
Cloud Scale Architecture
-
Scale to your needs, from 100 to 100,000+ compute and storage nodes
-
Resilient and proven software operating system based on the publish / subscribe state sharing foundation and evolving to NetDB for a network-wide software infrastructure for centralizing and streaming network state for improved visibility analytics
-
Open, standards-based design approach with MLAG at Layer-2, ECMP at Layer-3 with effective use of all available bandwidth in non-blocking modes while providing failover and resiliency
-
Network virtualization using overlay technologies such as VXLAN for seamless workload mobility network segmentation, and application extension
Scale to Meet Any Need
-
Scale for the most demanding environments, from 100 to 100,000+
-
Management and provisioning at scale with Arista EOS visibility applications and automation capabilities
-
Scale to 1,000s with Spline (TM)
-
Scale to 10,000 with MLAG
-
Scale to 100,000+ with ECMP or VXLAN
