The Arista 7280DR3-24 provides high-capacity routing for enterprise data centre leaf and aggregation deployments where predictable performance under load matters. Its deep buffering and 400GbE QSFP-DD ports help teams move more traffic per device while reducing bottlenecks across large fabrics.
As compute, storage and test traffic concentrate into fewer high-speed paths, infrastructure teams need fabric capacity that keeps pace without adding unnecessary device sprawl.
The Arista 7280DR3-24 is a 1RU 400GbE switch router for spine, DCI and aggregation deployments. It fits environments where teams need to consolidate traffic from dense compute, storage and application domains into fewer faster links.
With 24x QSFP-DD ports at 400G and 19,200Gbps switching capacity, the platform supports high-bandwidth routed fabrics. EOS gives operations a familiar operating model for day-to-day control.
Deep buffering and wire-speed forwarding help maintain predictable behaviour under load. That makes the switch router well suited to environments where many 100GbE flows must be aggregated into a smaller number of high-speed paths.
The result is a cleaner interconnect layer, less pressure on aggregation tiers, and more room to scale without redesigning the fabric. It also helps keep performance consistent as traffic patterns become more concentrated.

The Arista 7280DR3-24 is a high-speed networking platform for demanding data center environments, delivering a compact switching architecture designed to support dense interconnectivity and scalable operations.
QSFP-DD Port Architecture
The platform provides 24×QSFP-DD ports to support high-density connectivity in space-conscious network deployments.
High-Speed Forwarding Plane
It is built for maximum port speeds of 400G, enabling high-bandwidth links for modern data center traffic patterns.
Large Aggregate Capacity
The switch delivers 19,200 Gbps of switching capacity to sustain broad east-west traffic flows across the fabric.
Data Center Interconnect Role
Its compact 24-port design supports aggregation and interconnect functions where dense, high-speed switching is required.
Predictable Fabric Behavior
The switching architecture is designed to maintain consistent forwarding performance across high-capacity network workloads.
Deployment Flexibility
The platform can be used in environments that require high-speed connectivity without expanding the physical footprint excessively.
Capacity-Aligned Scaling
Its port density and throughput profile support incremental fabric growth within a high-bandwidth network design.
If you are planning high-density data center connectivity, our team can help align Arista switching architecture with throughput, port density, and fabric design requirements.

The Arista 7280DR3-24 is a fixed 400GbE switching platform for data-centre backbones and high-volume fabric aggregation, built for environments where large compute, storage and traffic domains are pushing past 100GbE limits.
When east-west traffic between compute clusters and storage arrays is growing, the 7280DR3-24 can sit as a compact 400GbE spine or aggregation layer, reducing the number of slower uplink tiers and keeping fabric movement efficient.
Studios moving uncompressed or high-resolution media across render farms, ingest systems and finishing suites need fewer bottlenecks and shorter transfer windows. This switch helps collapse several 100GbE paths into a smaller number of faster backbone links.
For finance teams running large analytics, pricing and back-testing workloads, the main pressure is moving big datasets predictably between compute and storage. The 7280DR3-24 provides the bandwidth needed without adding unnecessary aggregation complexity.
Large development estates generate constant internal traffic from build workers, container platforms and test systems. In these environments, the 7280DR3-24 gives platform teams a high-capacity spine that absorbs concurrent image, log and dataset movement.
Telecoms labs and edge-cloud pods often combine routers, traffic generators and appliance stacks that must be validated under realistic load. This platform aggregates multiple 100GbE flows into a simpler, higher-throughput fabric layer for service testing.
Our team can help design and deploy Arista 7280DR3-24 switching for data centres, media facilities, finance platforms, software development estates and telecoms labs, with practical support for sizing, integration and rollout.
