Description

The Arista 7260CX3-64E is a fixed-configuration, 2RU data centre switch from the 7260X3 Series, built for dense 100GbE leaf and spine tiers. It suits middle-of-row or end-of-row leaf and collapsed spine designs, and cloud, big data and virtualised environments with heavy east-west traffic. It runs Arista EOS.

This Enhanced 64E variant provides 64 QSFP100 ports (40/100GbE) plus 2 SFP+ ports, with wire-speed Layer 2 and Layer 3 forwarding at up to 12.8 Tbps FDX. Breakout cables allow up to 128 x 25GbE or 130 x 10GbE. Forwarding rate reaches 4.2 Bpps with 450 ns latency and a 42 MB dynamic packet buffer. This SKU has rear-to-front airflow and 2 hot-swap AC power supplies in a 1+1 redundant arrangement, with 4 hot-swap fans in an N+1 arrangement.

It accepts 40G QSFP+ and 100G QSFP28 optics, DACs and AOCs, plus 1G and 10G SFP/SFP+ optics on the 2 SFP+ ports. Ports 13, 15, 17, 19 and 46, 48, 50, 52 support QSFP transceivers up to 5W. It requires EOS 4.23.0 or later.
