Arista Modular Switches Aim At Scale Across Networks
Chip designs are advancing beyond lithography machine limits, making chiplets and high-bandwidth interconnects inevitable.
AI training workloads are also driving the need for scale out networks to connect datacenters or regions into a single logical datacenter.
Given all of the attention that leaf and spine network architectures have been getting, it's a bit retro to talk about big, beefy modular switches.
However, suppliers like Arista are still developing modular switches, such as the "Magnum" InfiniBand with 3,456 ports, designed for large-scale networks.
Author's summary: Arista develops modular switches for scale.
