We already talked quite a bit about white-box switch architecture and how networking software works. There were pieces about basics, ICOS, OpenSwitch. All squares, arrows, names, and other theoretical cliches, completely unbound from the material base.

This one will be a more physical piece, looking inside one of the most advanced products on the market - a 12.8Tbps box with 32x400G QSFP-DD ports. As of now, it’s cutting-edge hardware, being deployed by hyper-scalers, and only started getting tentative interest outside these huge guys.

Today we are covering Aurora 820 by Netberg with the Broadcom Tomahawk3 BCM56980 at the core.
