Description
Description
The Arista 7280R3A is a 2RU fixed data centre switch router built for cloud and enterprise spine and leaf designs, Internet border and peering, carrier edge VPN and EVPN services, data centre interconnect and carrier core transport. This K model combines large routing tables with built-in TunnelSec encryption.
It provides 48 x 100G QSFP100 ports and 6 x 400G QSFP-DD ports, with 7.2 Tbps (14.4 Tbps full duplex) of throughput, 2.7 Bpps forwarding and latency from 3.8 us. An 8 GB packet buffer, an eight-core x86 CPU, 64 GB of system memory and a 120 GB SSD support demanding routing and telemetry workloads. FlexRoute supports over 5M IPv4 routes, and TunnelSec delivers MACsec, IPsec and VXLANsec encryption on all ports. This SKU uses rear-to-front airflow with two hot-swap 1500W AC power supplies in a 1+1 arrangement and four N+1 hot-swap fans.
It accepts QSFP and QSFP100 optics from 10G to 100G with breakout, QSFP-DD optics up to 400G and an OSFP-LS port for 400G-ZR deployments. It runs Arista EOS 4.31.1 or later.
