Arista 7280R Series

The Arista 7280R Series represents a high-performance family of purpose-built fixed configuration routing and switching platforms engineered for demanding enterprise datacenter networks, cloud service providers, and carrier routing environments. Combining high-density 100GbE and 400GbE wire-speed performance with ultra-deep packet buffers, the 7280R Series is optimized to prevent packet loss during intense traffic bursts common in modern storage networks, content delivery backbones, and high-performance computing clusters. Powered by Arista’s advanced, single-binary Extensible Operating System (EOS), the switch delivers state-sharing architecture that ensures unmatched software stability, self-healing modularity, and zero-downtime live software patching. From a cybersecurity and network defense perspective, the 7280R Series incorporates hardware-accelerated wire-speed MACsec encryption, safeguarding inter-datacenter data transit against eavesdropping and man-in-the-middle attacks. Furthermore, EOS provides granular flow telemetry through CloudVision, streaming real-time network state and flow records (sFlow and IPFIX) to centralized security monitoring and analytics platforms. With robust support for advanced routing protocols, BGP EVPN overlays, and granular Access Control Lists (ACLs), the Arista 7280R Series delivers scalable, resilient, and highly secure network infrastructure for enterprise core and edge routing.
