The Arista 7280DR3K-24 is built for data centre leaf and interconnect deployments that need high-capacity routing with strong operational control. Its 400GbE connectivity and dynamic routing help enterprise teams scale large fabrics while preserving separation and performance.
As fabrics grow denser and interconnect demands rise, infrastructure teams need routed capacity that can carry more traffic while keeping policy, segmentation and control-plane growth under control.
The Arista 7280DR3K-24 is a Data Centre switch router for leaf deployments in demanding edge and core environments. It is intended for teams building 400GbE routed fabrics where throughput and route scale must grow together.
With 24×QSFP-DD ports at up to 400G, the platform fits dense interconnect designs without forcing a redesign around bandwidth limits. That makes it a practical fit for large fabrics, peering layers and core aggregation points.
It gives operators room to scale tenant traffic, service domains and policy structures within one fabric. The result is a cleaner operating model with less pressure to split workloads across multiple tiers.
The Arista 7280DR3K-24 helps simplify high-scale routed infrastructure where capacity, separation and operational visibility all matter. Our team can help you assess whether it fits your deployment model.
The Arista 7280DR3K-24 is a high-capacity data centre switching platform designed for leaf, spine, and interconnect deployments where predictable forwarding and scalable fabric design matter.
High-Density Uplink Platform
The switch provides 24×QSFP-DD ports to support dense fabric interconnects in modern data centre architectures.
400G Forwarding Headroom
Maximum port speed reaches 400G to align the platform with high-bandwidth aggregation and spine-tier requirements.
Large Switching Envelope
The platform delivers 19,200 Gbps of switching capacity to support high-throughput network designs.
Unified Fabric Role
Its dense port architecture supports deployment in roles where a compact switch must carry heavy east-west traffic across the network fabric.
Infrastructure-Focused Design
The platform is intended for enterprise data centre environments where operational consistency and scalable connectivity are primary design goals.
Architecture-Led Planning
The switching profile enables network teams to size fabric layers around bandwidth demand rather than individual access-port expansion.
Deployment Flexibility
The product can be applied in new or refurbished environments without changing the underlying platform role or architectural intent.
If you are planning a high-bandwidth data centre fabric, our team can help map the Arista 7280DR3K-24 to your topology, uplink strategy, and growth requirements.

The Arista 7280DR3K-24 is a 400GbE routed core and DCI switch for environments where throughput, route scale and policy growth all matter. It fits large fabrics, segmented platform networks and service-heavy interconnects that need headroom without redesign.
In colocation and enterprise data centres, the 7280DR3K-24 can anchor routed cores or DCI borders where EVPN scale, VRFs and policy tables are under constant pressure. It helps teams avoid splitting tenants across extra devices.
Financial infrastructure teams can use it where market feeds, trading systems and compliance zones must move data quickly but remain tightly separated. The larger control-plane headroom supports route growth without compromising operational segregation.
For energy and utilities, it suits links between control centres, analytics platforms and enterprise systems carrying large telemetry volumes. The design supports heavy transport while preserving domain separation and visibility across operational networks.
Software development teams building private-cloud fabrics can place this model in the backbone where Kubernetes overlays, CI pipelines and tenant networks generate route churn and east-west traffic. It provides capacity for shared infrastructure at scale.
Telecom operators can deploy it at the edge or in MEC aggregation where customer VRFs, service chains and network slices expand quickly. It keeps high-volume traffic moving while maintaining the logical separation service teams rely on.
Our team can help design and deploy Arista 7280DR3K-24 fabrics for data centres, finance, energy, software platforms and telecom environments, with attention to routing scale, segmentation and operational recovery requirements.
