Description

The Arista 7260X3 series switch is a 2RU data centre platform built for middle or end-of-row leaf and collapsed spine tiers, 100GbE top-of-rack and spine roles, high-density storage and low-latency financial trading networks. It runs Arista EOS, the same software used across all Arista products, which keeps network administration consistent.

This 64E Enhanced model provides 64 QSFP100 ports for 40/100GbE plus 2 SFP+ ports, with up to 128 x 10G, 25G or 50G connections available through breakout cables. System throughput is 12.8 Tbps with forwarding of up to 4.2 billion packets per second and latency from 450ns. A 42MB shared dynamic packet buffer helps absorb micro-bursts. This SKU is DC powered with 1900W-class supplies and Front-to-Rear airflow, and the enhanced power and cooling design supports 4.5W-rated optics on every port.

QSFP100 ports accept 40G and 100G QSFP optics as well as DAC and breakout cables, while the two SFP+ ports take SFP+ optics. Hot-swappable power supplies and N+1 fans provide redundancy.
