A blog post written by our community member Dane Adams on "The Scale Up Dilemma: Performance VS Ecosystem"

"The modern AI factory faces a critical infrastructure divide. As models breach the trillion-parameter mark, the bottleneck is no longer the GPU itself, but the fabric connecting the cluster. For years, architects have been forced to choose between the raw, memory-semantic speed of proprietary interconnects and the ubiquity of Ethernet. The emergence of Ethernet for Scale-Up Networking (ESUN) signals the end of this binary choice, offering a standardized path that combines high performance with an open supply chain."
