Description

The Arista 7280R3A is a fixed 2RU data centre switch router with 54 x 400GbE QSFP-DD ports. This R3AK variant adds TunnelSec encryption (MACsec, IPsec and VXLANsec) and the larger routing-table profiles, making it suited to large-scale cloud data centres, spine and leaf fabrics, Internet peering and border routing, and encrypted data centre interconnect. It runs Arista EOS and is also used in carrier edge, metro aggregation and MPLS or SR-TE cores.

The QSFP-DD ports break out to as many as 216 x 100G, 348 x 50G or 348 x 25/10G interfaces, and can also run QSFP+ optics at 40G. Throughput is 21.6 Tbps (43.2 Tbps full duplex) at 8.1 Bpps, with latency from 3.8 us and a 24 GB packet buffer. TunnelSec runs at wire speed on all ports, and the large-scale routing profiles support over 5M IPv4 routes with FlexRoute. This SKU has front-to-rear airflow, 2 x hot-swap AC power supplies (1+1) and 4 x hot-swap fans (N+1).

Two OSFP-LS line-system ports support the AMP-ZR amplifier for dense 400G DWDM, and the switch supports 400G ZR and ZR+ optics. EOS 4.29.1 or later is required, and the switch is managed with CloudVision.

FAQs

Q: Does the TunnelSec encryption need a licence?
A: TunnelSec is an EOS licensed feature and needs a licence file. The switch runs EOS feature licence Group 5 with a minimum of EOS 4.29.1.

Q: What power supplies does this SKU use?
A: It uses 2 x hot-swap PWR-3001 AC power supplies in a 1+1 redundant arrangement, with an IEC 60320 C20 input. Typical draw is 933 W and maximum draw is 1715 W, excluding transceivers.

Q: Can the 400G ports run at lower speeds?
A: Yes. The QSFP-DD ports break out to 4 x 100G, 50G or 25/10G, and also accept QSFP+ optics at 40G. Maximum port counts depend on the transceivers and cables used.

Q: What is the airflow direction?
A: This SKU has front-to-rear airflow, using 4 x hot-swap FAN-7012H fans in an N+1 arrangement.

Q: How does this model differ from other 7280R3A variants?
A: The 7280DR3AK-54 is the large-routes variant with TunnelSec (MACsec, IPsec and VXLANsec), front-to-rear airflow and 2 x AC power supplies, aimed at large-scale routing and encrypted data centre interconnect.
