Arista Modular Switches Aim At Scale Across Networks
Chip designs are busting out beyond the reticle limits of lithography machines, making chiplets and high-bandwidth, in-package die-to-die interconnects inevitable.
AI training workloads are also busting through datacenter walls, making scale out networks to lash together datacenters or even multiple regions into a single, logical datacenter just as inevitable.
Despite the attention on leaf and spine network architectures, big, beefy modular switches like the "Magnum" InfiniBand beast are still relevant, with 3,456 ports, invented by Andy Bechtolsheim for the Constellation supercomputer.
Given all of the attention that leaf and spine and now super spine network architectures have been getting for the past decade, you might be thinking it is a bit retro for any switch or router supplier to be talking about big, beefy modular switches.
