OCP Summit 2021: Open networking hardware lays the groundwork for the metaverse

What this post added

This post details Meta's adoption of open networking hardware and the migration of its data center network to the Open Compute Project (OCP) Switch Abstraction Interface (SAI). It introduces the Wedge 400/400C next-generation Top-of-Rack (TOR) switches, highlighting their increased switching capacity (12.8 Tbps) and performance improvements over previous models. The post also describes the migration of FBOSS (Facebook Open Switching System) to support SAI, enabling easier integration with multiple ASIC vendors. Furthermore, it announces the deployment of 200G optics and next-generation 200G/400G fabric switches like Minipack2 and Arista 7388X5, which offer higher bandwidths (25.6 Tbps) and reduced power consumption per bit, laying the groundwork for future computing platforms like the metaverse.
