The Arista 7280R3 Series 400G Universal Spine Platform delivers 24 ports of 400GbE QSFP-DD connectivity in a compact 1RU fixed configuration, engineered for hyperscale data center and high-performance network deployments. Built on Arista's proven architecture with a Broadcom Trident 4 forwarding ASIC, the DCS-7280R3-24E achieves an exceptional 9.6 Tbps switching capacity and approximately 3.6 Bpps forwarding rate, enabling sub-microsecond cut-through forwarding latency that eliminates processing bottlenecks. This platform supports comprehensive Layer 3 routing protocols—BGP, OSPF, IS-IS, RIP, PIM, IGMP, SRv6, and MPLS—alongside advanced overlay technologies including EVPN, VXLAN, and MPLS for flexible network virtualization. Critical data center features such as ECN, PFC, RoCE, sFlow, and ECMP deliver congestion control, load balancing, and telemetry capabilities essential for demanding workloads.
Network architects and infrastructure teams standardizing on Arista select the 7280R3 Series to consolidate spine and border leaf roles while maintaining deterministic, low-latency performance. Organizations requiring carrier-grade reliability benefit from redundant hot-swappable AC and DC power supply options, hot-swappable fan modules with front-to-rear and rear-to-front airflow flexibility, and UL, CE, and FCC Class A safety certifications. Operations teams gain unified management through Arista EOS with streaming telemetry via gNMI/gRPC, alongside NETCONF, RESTCONF, and OpenConfig support. CloudVision Portal and CloudVision as-a-Service integration enable multi-site visibility and orchestration, while zero-touch provisioning via Arista ZTP accelerates deployment cycles. The platform operates reliably across 0°C to 45°C environmental conditions, meeting data center thermal constraints.
Our enterprise IT hardware team will connect you with regional support and fulfillment options tailored to your deployment timeline.
