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 given to leaf and spine network architectures, big, beefy modular switches are still relevant, such as 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 modular switches aim to provide scale across networks, hitting scale out too.
