Description

The Arista 7280R4 Series 2RU switch router delivers 32x800GbE QSFP-DD ports with 25.6 Tbps of non-blocking bandwidth, purpose-built for Cloud, AI/ML, Data Centre Interconnect, and Service Provider backbone deployments. Powered by a 7th generation architecture with Virtual Output Queueing (VOQ) and dynamic deep buffers up to 32 GB, it delivers lossless performance at spine scale — making it an ideal choice for high-density 800G fabric builds and IP peering environments. Front-to-rear airflow and dual AC power supplies support standard hot-aisle/cold-aisle data centre configurations.

Running Arista EOS, the DCS-7280R4-32DE-F supports EVPN-VXLAN, MPLS, Segment Routing, and FlexRoute™ for internet-scale routing up to 5 million routes. Line-rate TunnelSec AES-256-GCM encryption, MACsec, IPsec, and VXLANsec deliver comprehensive data security without throughput penalty. Integrated with Arista CloudVision® for network-wide automation and streaming telemetry, this platform supports 50G through 800G attached storage systems and is compatible with the full Arista 7280R ecosystem for seamless migration and investment protection.

FAQs

Q: What is the Arista DCS-7280R4-32DE-F best suited for?
A: The DCS-7280R4-32DE-F is designed for high-density Cloud, AI/ML fabric, Data Centre Interconnect (DCI), IP Peering, CDN, IP Storage, and Service Provider backbone deployments. Its 32x800GbE QSFP-DD ports and 25.6 Tbps non-blocking bandwidth make it an ideal spine or core switch for next-generation 800G networks.

Q: Does this switch support encryption at line rate?
A: Yes. The DCS-7280R4-32DE-F supports line-rate TunnelSec AES-256-GCM encryption along with MACsec, IPsec, and VXLANsec for point-to-point and end-to-end data security — all without impacting throughput performance.

Q: What routing protocols and overlays does the 7280R4 support?
A: The platform supports EVPN-VXLAN, MPLS, Segment Routing, and FlexRoute™ for internet-scale routing up to 5 million routes. It also supports BGP, OSPF, IS-IS, and a full suite of L2/L3 protocols via Arista EOS.

Q: What is the buffer capacity and why does it matter for AI/ML workloads?
A: The DCS-7280R4-32DE-F features dynamic deep buffers up to 32 GB using a VOQ (Virtual Output Queueing) architecture. This is critical for AI/ML and high-performance computing workloads where traffic bursts can cause congestion — deep buffering ensures lossless, in-order packet delivery across the fabric.

Q: Can this switch be managed via Arista CloudVision?
A: Yes. Running Arista EOS, the DCS-7280R4-32DE-F integrates natively with Arista CloudVision® for network-wide workload orchestration, automation, and real-time streaming telemetry. It also supports Inband Network Telemetry (INT) and accelerated sFlow for per-flow traffic visibility.

Q: Can I purchase the Arista DCS-7280R4-32DE-F in Australia through IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian B2B IT hardware specialist with the Arista DCS-7280R4-32DE-F available for local procurement. Contact our team for pricing, lead times, and configuration advice tailored to your deployment requirements.
