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 100GbE performance at enterprise scale. Tested, trusted, and ready to deploy.
This refurbished Arista DCS-7280CR2A-30-F is a high-density, carrier-class data center switch delivering 30 ports of 100GbE QSFP28 connectivity with front-to-rear airflow. Part of the Arista 7280R2A Series, every unit has been professionally tested, fully inspected, and reset to factory defaults — ensuring dependable, ready-to-deploy operation backed by WhaleyComm's ISO 9001-certified processes.
The DCS-7280CR2A-30-F is engineered for cloud-scale spine and aggregation deployments where throughput, buffer depth, and routing scale are non-negotiable. The platform runs Arista EOS, delivering advanced automation, streaming telemetry, and deep programmability across protocols including VXLAN, EVPN, MPLS, BGP, OSPF, and IS-IS. Each QSFP28 port supports 100G, 40G, and breakout configurations to 4x25G or 4x10G, providing flexible cabling options for mixed-density environments. AlgoMatch hardware and expanded memory further extend the platform's capabilities for large-scale routing tables and advanced traffic steering.
Purchasing refurbished from WhaleyComm means enterprise-grade Arista hardware at a fraction of new list pricing — without compromise on reliability. With 25+ years of experience and 5,000+ enterprise customers served, WhaleyComm is the trusted source for mission-critical network infrastructure.

Ideal Use Cases
Data Center Spine Layer
The DCS-7280CR2A-30-F delivers the non-blocking throughput and deep buffer architecture required for high-density spine deployments in modern leaf-spine fabrics, supporting ECMP and EVPN-VXLAN overlays at scale.
Cloud and Hyperscale Aggregation
With 30 ports of 100GbE and up to 6.4 Tbps switching capacity, this platform is purpose-built for aggregation layers in cloud and enterprise data centers requiring massive east-west traffic handling.
High-Performance Computing Environments
Ultra-deep buffers absorb traffic bursts common in HPC and storage-heavy workloads, preventing packet loss and maintaining throughput integrity across all ports at wire speed.
Large-Scale BGP and MPLS Routing
AlgoMatch hardware and expanded memory enable support for very large routing tables, making this switch well suited for service provider edge and enterprise core routing deployments.
Network Telemetry and Automation Platforms
Arista EOS provides streaming telemetry, DANZ visibility, LANZ congestion monitoring, and open APIs — enabling deep integration with monitoring, orchestration, and automation frameworks.
Data Center Refresh and Cost Optimization
Organizations refreshing aging 40GbE infrastructure can adopt enterprise-validated 100GbE capacity at significantly reduced cost compared to new hardware pricing.
