Arista Modular Switches
Arista Modular Switches aim at scale across networks and hit scale out. Chip designs are surpassing the limits of lithography machines, making chiplets and high-bandwidth interconnects necessary.
AI training workloads are also driving the need for scale out networks, connecting multiple datacenters or regions into a single logical datacenter.
Chip designs are busting out beyond the reticle limits of lithography machines, making chiplets and high-bandwidth, in-package die-to-die interconnects inevitable.
Despite the focus on leaf and spine network architectures, big modular switches are still relevant, as seen in the "Magnum" InfiniBand switch with 3,456 ports.
