Every WhaleyComm unit is professionally tested, reset to factory defaults, and certified by our in-house engineers — the same standard trusted by 5,000+ organisations across 25 years. Not a refurb marketplace. A certified lifecycle partner.
Wire-speed performance at data center scale. Backed by 25+ years of enterprise trust.
This refurbished Arista DCS-7280QR-C72 (MPN: DCS-7280QR-C72-R) is a professionally tested, factory-reset 72-port data center switch from the Arista 7280R Series. Combining 56 x 40GbE QSFP+ ports and 16 x 100GbE QSFP100 ports, this unit delivers the port density and flexibility that modern cloud, hyperscale, and enterprise core networks demand — at a fraction of new list price.Built on Arista EOS, the DCS-7280QR-C72 provides up to 6.4 Tbps of switching capacity and up to 2.88 billion packets per second of forwarding performance, all at wire speed. Ultra-deep buffers of up to 32GB absorb microbursts and eliminate congestion without dropping packets — a critical advantage in latency-sensitive workloads. The platform supports VXLAN, EVPN, MLAG, ECMP, BGP, OSPF, IS-IS, MPLS, and integrates natively with Arista CloudVision for end-to-end network automation and telemetry. Redundant hot-swappable power supplies and fans, along with configurable front-to-rear or rear-to-front airflow, ensure continuous operation in production data centers.
Every unit sold by WhaleyComm is put through our ISO 9001-certified testing process — full power-on diagnostics, port-by-port verification, firmware check, and factory reset — before it ships. Sourced from enterprise environments, these units are certified under R2v3, e-Stewards, and UNEDA standards. Choosing refurbished means you get proven Arista hardware at a significantly lower cost while keeping functional equipment out of the waste stream.

Ideal Use Cases
Leaf-Spine Data Center Fabric
The DCS-7280QR-C72 is purpose-built for leaf-spine architectures, providing the port density and 40G/100G flexibility needed to scale east-west traffic in modern data center fabrics without bottlenecks.
Cloud and Hyperscale Core Switching
With 6.4 Tbps switching capacity and 32GB of deep buffer memory, this switch handles the bursty, high-volume traffic patterns common in cloud and hyperscale environments while maintaining wire-speed forwarding.
VXLAN EVPN Overlay Networks
Native VXLAN and EVPN support makes the DCS-7280QR-C72 an ideal spine or border leaf device for deploying scalable multi-tenant overlay networks across large enterprise and service provider environments.
High-Performance Compute and AI/ML Interconnect
Ultra-deep buffers and low-latency wire-speed performance make this switch well suited for HPC clusters and AI/ML training workloads where congestion and packet loss directly impact job completion times.
Network Automation and Telemetry Deployments
Full Arista EOS support, CloudVision integration, ZTP, sFlow, LANZ, and DANZ give network teams comprehensive automation, streaming telemetry, and advanced traffic monitoring capabilities out of the box.
Enterprise Core Network Refresh
Organizations upgrading aging core infrastructure can deploy the DCS-7280QR-C72 as a cost-effective, carrier-class replacement that supports OSPF, BGP, IS-IS, MPLS, and MLAG for robust enterprise routing and redundancy.
