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 busting through datacenter walls, making scale out networks to lash together datacenters or even multiple regions into a single, logical datacenter just as inevitable.
Given the attention on leaf and spine network architectures, it's notable that switch or router suppliers are discussing big, beefy modular switches, like the "Magnum" InfiniBand beast with 3,456 ports.
Andy Bechtolsheim invented the "Magnum" for the Constellation supercomputer, which was acquired by Sun Microsystems and shipped in June 2007.
Arista's approach focuses on scale across networks and scale out.
