Description

The Arista 7280R4 Series data centre switch router delivers 32x800GbE QSFP-DD ports and 25.6 Tbps of non-blocking throughput in a compact 2RU fixed system — purpose-built for Cloud, AI/ML fabric, Data Centre Interconnect, and Service Provider backbone deployments. The DCS-7280R4K-32DE-F features the FlexRoute engine for Internet-scale routing at 5M+ IP routes, line-rate TunnelSec AES-256-GCM encryption (MACsec, IPsec, VXLANsec), and dynamic deep buffers up to 32 GB for lossless spine and incast traffic management.

Running Arista EOS, this 7th-generation platform supports EVPN-VXLAN, MPLS, and Segment Routing alongside 512-way ECMP for large leaf-spine architectures. The 7001 Series Supervisor-L provides an 8-core 3.3 GHz CPU, 64 GB RAM, and 480 GB NVMe for advanced automation including Zero Touch Provisioning, OpenConfig, and CloudVision integration. Front-to-rear airflow with 2x AC power supplies suits standard hot-aisle/cold-aisle data centre builds. Order now at iptrading.com.au — trusted by Australian IT professionals.

FAQs

Q: What is the DCS-7280R4K-32DE-F designed for?
A: The DCS-7280R4K-32DE-F is designed for demanding Cloud, AI/ML fabric, Data Centre Interconnect (DCI), and Service Provider backbone environments. Its combination of 32x800GbE ports, 25.6 Tbps non-blocking throughput, 5M+ route scale, and line-rate encryption makes it ideal for high-density spine and border-leaf deployments.

Q: What does the '-F' suffix mean in the SKU?
A: The '-F' suffix denotes front-to-rear airflow, meaning cool air enters from the front (port side) and exhausts out the rear. This is the standard airflow direction for conventional hot-aisle/cold-aisle data centre configurations.

Q: Does this switch support hardware encryption?
A: Yes. The 7280R4K delivers line-rate TunnelSec AES-256-GCM encryption across all 32x800GbE ports simultaneously, with support for MACsec (L2), IPsec (L3), and VXLANsec (overlay) — ensuring no throughput penalty for encrypted traffic.

Q: How many IP routes can this platform support?
A: The 7280R4K variant includes the FlexRoute™ engine, which scales to over 5 million IPv4/IPv6 routes — making it suitable for full Internet routing tables, large MPLS VPN deployments, and complex multi-tenant DCI scenarios.

Q: Is the Arista DCS-7280R4K-32DE-F compatible with existing Arista infrastructure?
A: Yes. As a 7th-generation 7280R Series platform, it runs Arista EOS and integrates natively with CloudVision for unified management. It supports EVPN-VXLAN, MLAG, MPLS, and Segment Routing, enabling seamless integration into existing Arista leaf-spine and DCI architectures.

Q: Can I purchase the Arista DCS-7280R4K-32DE-F in Australia from IP Trading?
A: Yes. IP Trading (iptrading.com.au) is a trusted Australian B2B IT hardware reseller supplying Arista products to enterprise, government, and service provider customers across Australia. Contact us or order online for pricing and availability.
