Description

The Arista 7388X5 is a 4RU modular data centre switch built on a single 25.6 Tbps packet processor. It is aimed at hyperscale cloud networks, AI/ML clusters, big data farms and I/O-intensive data centres, and suits spine or high-radix roles where fewer network tiers are wanted.

This SKU is the system bundle with 80 x 200G and 24 x 400G QSFP-DD ports, 104 ports in total, with front-to-rear airflow. The DCS-7388-CH chassis has one supervisor slot and eight module slots. System capacity reaches 25.6 Tbps and 10.66 Bpps, with latency from 825 ns and a 114 MB shared packet buffer. The supervisor has a multi-core x86 CPU, 32 GB RAM and a 512 GB SSD. Four power supply slots run N+N redundant and five fan modules run N+1 redundant. Maximum system power consumption is 3,458 W. It runs Arista EOS 4.29.1 or later, using Fixed Group 4 feature licences.

The interface modules DCS-7388-16CD2, DCS-7388-8DR and DCS-7388-8D all fit the DCS-7388-CH chassis, and the switch supports 10G to 400G pluggable optics and cables. It is managed with CloudVision.
