Arista EOS™ was designed to provide a foundation for the business needs of next-generation datacenters and cloud networks. EOS is a highly modular software design based on a unique multi-process state sharing architecture that completely separates networking state from the processing itself. This enables fault recovery and incremental software updates on a fine-grain process basis without affecting the state of the system.
Arista EOS provides extremely robust and reliable data center communication services while delivering security, stability, openness, modularity and extensibility. This unique combination offers the opportunity to significantly improve the functionality and evolution of next generation data centers.
