Description

The Arista 7260X3 Series 7260CX3 is a fixed-configuration 2RU data centre switch built for 100GbE top-of-rack, leaf and collapsed-spine tiers. It also suits high-density storage, low-latency financial trading, and AI/ML and cloud environments that need 4.5W optics on every port.

This Enhanced (E) model has 64 QSFP100 ports supporting 40/100GbE, plus 2 SFP+ ports. Breakout cables provide up to 128 x 10G, 25G or 50G connections. It delivers 6.4 Tbps (12.8 Tbps full duplex) throughput and 4.2 Bpps forwarding, with latency from 450 ns and a 42 MB dynamic shared packet buffer. The Enhanced variant adds power and cooling headroom through 2 x 1900W AC hot-swap power supplies in a 1+1 arrangement and high-speed fans, with front-to-rear airflow.

It runs Arista EOS (minimum 4.23.0) and belongs to EOS Feature License Group 3, with optional licences for enhanced L3 routing, VXLAN and VM Tracer, monitoring and automation, and FLX-Lite routing. It supports 40G QSFP, 100G QSFP100 optics, DAC and AOC cabling, 10G/1G SFP+ optics and QSFP breakout cables.
