You couldn't have picked a better/worse duo in tech to be wrong on such an assertion. Adding to sibling comment about Google, Meta[1] built 2 large-scale production training clusters for science: one with Infiniband, the other one with a custom RDMA over RoCE fabric. > Custom designing much of our own hardware, software, and network fabrics allows us to optimize the end-to-end experience for our AI researchers while ensuring our data centers operate efficiently. > With this in mind, we built one cluster with a remote direct memory access (RDMA) over converged Ethernet (RoCE) network fabric solution based on the Arista 7800 with Wedge400 and Minipack2 OCP rack switches. Google, Meta and Netflix are among the most obsessive on optimizing their infrastructure - it's bold to assume they haven't looked at their COTS network gear and thought "hmmm..." 1. https://engineering.fb.com/2024/03/12/data-center-engineering/building-metas-genai-infrastructure/ https://engineering.fb.com/2024/03/12/data-center-engineerin...
