Description

The Arista 7280R4 Series Data Center Switch Router delivers 32 x 800GbE OSFP ports with 25.6 Tbps of non-blocking switching capacity in a compact 2RU form factor, making it one of the highest-density 800G platforms available for AI/ML fabric, cloud spine, and service provider IP routing deployments. Built on Arista's 7th-generation architecture with a deep-buffer Virtual Output Queueing (VOQ) design and FlexRoute™ engine, it supports Internet-scale routing tables, EVPN-VXLAN, MPLS, Segment Routing, and 512-way ECMP — eliminating head-of-line blocking even under extreme traffic bursts. The DCS-7280R4-32PE-F ships with front-to-rear airflow and dual AC power supplies, and natively supports 400G and 800G ZR/ZR+ DWDM coherent optical modules for high-capacity WAN integration.

Powered by Arista EOS® with Zero Touch Provisioning, OpenConfig, and comprehensive streaming telemetry, this platform integrates seamlessly into automated, programmable data centre environments. MACsec, IPsec, and VXLANsec encryption provide end-to-end security across leaf-spine and DCI topologies. Order now at iptrading.com.au — trusted by Australian IT professionals.

FAQs

Q: What makes the DCS-7280R4-32PE-F suitable for AI/ML and cloud data centre deployments?
A: The 7280R4 delivers 32 ports of 800GbE density with 25.6 Tbps non-blocking bandwidth and a deep-buffer VOQ architecture that eliminates head-of-line blocking — critical for the bursty, all-to-all traffic patterns of AI/ML training clusters and hyperscale cloud spine fabrics.

Q: Does this switch support coherent optical (ZR/ZR+) modules?
A: Yes. The DCS-7280R4-32PE-F is optimised for 400G and 800G ZR/ZR+ OSFP coherent DWDM modules. Combined with Arista's ZR Line System, up to 8 x 800ZR modules can be multiplexed to deliver 6.4 Tb/s over a single fibre pair, making it ideal for DCI and metro WAN integration.

Q: What routing protocols and overlay technologies are supported?
A: The FlexRoute™ engine supports Internet-scale routing tables with EVPN-VXLAN, MPLS, Segment Routing (SR-MPLS and SRv6), BGP, OSPF, and IS-IS. It also supports up to 512-way ECMP for highly balanced traffic distribution across large leaf-spine topologies.

Q: What security capabilities are built into the 7280R4?
A: The platform supports MACsec (AES-256-GCM), IPsec, and VXLANsec for comprehensive point-to-point and end-to-end encryption. The R4K variant adds wire-speed TunnelSec encryption. Algorithmic ACLs are supported via the flexible pipeline for granular traffic policy enforcement.

Q: How is the DCS-7280R4-32PE-F managed and automated?
A: It runs Arista EOS® — a single, consistent network operating system with Zero Touch Provisioning (ZTP), OpenConfig/YANG model support, streaming telemetry, and full CLI/API automation. This enables rapid deployment and integration with modern DevOps and network-as-code workflows.

Q: Can I purchase the Arista DCS-7280R4-32PE-F in Australia through IP Trading?
