Arista 7300 Technical Architecture

The Arista 7300X Series is designed with the latest in system on chip (SoC) silicon and software. The 7300X Series architecture is optimized for fully meshed east-west traffic patterns with mixed traffic loads found in both private and public cloud networks.

The 7300X Series modular switches are designed for continuous operations with system wide monitoring of hardware and software components, simple serviceability and reversible airflow options. The series offers high availability of all critical components with redundant supervisors, power supplies, fabric and fan modules.
