Description

The Arista 7260X3 Enhanced (64E) is a 2RU data centre switch for 100GbE top-of-rack and spine tiers, middle or end-of-row leaf and collapsed spine designs, high-density storage and low-latency financial trading. It runs Arista EOS and suits big data, cloud, virtualised and traditional data centre builds.

The switch provides 64 QSFP100 ports (40GbE and 100GbE, with breakout to 10G, 25G and 50G) plus 2 SFP+ ports, for up to 12.8 Tbps of full duplex throughput and a 4.2 Bpps forwarding rate. Latency starts from 450 ns and the 42 MB dynamic packet buffer helps absorb microbursts. This SKU is the DC-powered variant with rear-to-front airflow, using 1900W DC hot-swap power supplies (40-72 VDC input) in a 1+1 redundant arrangement with N+1 hot-swap fans. The Enhanced 64E model gives extra power and cooling headroom, so ports can carry optics up to 4.5W, and up to 5W on selected ports.

QSFP ports accept 40G and 100G optics and cables, while the SFP+ ports take 10G modules and 1GbE SX, LX or TX. Feature licences are the Group 3 fixed-switch licences, with a minimum EOS of 4.23.0.
