Description

The Arista 7280R4 is a 2RU deep-buffer data centre switch router built for cloud, AI/ML and Internet-edge deployments. It suits spine and leaf fabrics, peering and border routing, and data centre interconnect where ultra-deep buffering and large route scale matter.

This -F model provides 32 x 800GbE OSFP ports alongside 8 x SFP25 ports, with 25.6 Tbps of throughput (51.2 Tbps full duplex) and 9.6 Bpps forwarding. A 32GB packet buffer using a Virtual Output Queue architecture keeps latency from 3.8 us. It is the standard non-K model with front-to-rear airflow and two hot-swap AC power supplies in 1+1 redundancy, so it does not include TunnelSec encryption. An eight-core x86 CPU, 64GB of memory and a 480GB SSD support EOS, and PTP with SyncE and an OCXO provide precision timing.

The OSFP ports accept 100G to 800G modules, including 400G and 800G ZR and ZR+ coherent optics, and two QSFP-LS ports drive the ZR line system amplifier. The switch runs Arista EOS with Group 5 fixed-switch feature licences.

FAQs

Q: Does this switch need a software licence?
A: It runs Arista EOS and uses Group 5 fixed-switch feature licences, with a minimum of EOS 4.35.0. Optional licences cover Enhanced L3, Virtualization and Monitoring and Automation features.

Q: Does the DCS-7280R4-32PE-F support TunnelSec encryption?
A: No. TunnelSec (MACsec, IPsec and VXLANsec) is available only on the 7280R4K model and needs a licence file. This is the standard non-K model.

Q: What power supplies does it use?
A: It uses two hot-swap PWR-3211 3200W supplies in 1+1 redundancy, in the AC configuration for this SKU. The PWR-3211-HV input range is 200-277 VAC or 240-380 VDC.

Q: Which optics does it work with?
A: The OSFP ports accept 100G to 800G modules, including 400G and 800G ZR and ZR+ coherent optics. Two QSFP-LS ports connect the AMP-ZR amplifier used with the ZR line system.

Q: What is the airflow direction?
A: This -F model uses front-to-rear airflow, cooled by four hot-swap fans in N+1 redundancy.
