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 Andy Bechtolsheim's invention featuring 3,456 ports for the Constellation supercomputer.

Chip designs are busting out beyond the reticle limits of lithography machines, making chiplets and high-bandwidth, in-package die-to-die interconnects inevitable.

Arista modular switches aim to provide scale across networks and hit scale out, too.

Author's summary: Arista modular switches scale networks.
