NVIDIA GTC 2025: Hyperscaler-Inspired Scale-Out Rack Architecture

 

At NVIDIA GTC 2025, Astera Labs showcased how hyperscalers can gain smart connectivity and optionality for NVIDIA rack-scale Blackwell deployments. We showcased modular architecture with a Scorpio IO Switch Board with two NICs connected via the Aries Retimer Mezzanine Board to the GB200. In this set-up, we show how the third-party NICs can provide maximum bandwidth to saturate the Blackwell GPU.
