Arista Modular Switches Aim At Scale Across Networks
Chip designs are surpassing the limits of lithography machines, leading to the development of chiplets and high-bandwidth interconnects.
AI training workloads are also driving the need for scale-out networks, connecting multiple datacenters or regions into a single logical datacenter.
Given all of the attention that leaf and spine network architectures have been getting, it's notable that switch or router suppliers are discussing big, modular switches.
Examples like the "Magnum" InfiniBand switch, with 3,456 ports, demonstrate the ongoing relevance of modular switches in modern networking.
