Overview
The AS-8126GS-NB3RT is the AMD side of Supermicro’s air-cooled HGX B300 range: two EPYC 9005 processors host the eight Blackwell Ultra GPUs, which talk to each other over NVLink with NVSwitch and to the processors over PCIe 5.0. ConnectX-8 SuperNICs for the cluster fabric are part of the system, and there is room for up to two BlueField-3 DPUs alongside them. New, configured to order and supplied through Supermicro’s authorised partners. Both the configuration and the allocation are fixed by the manufacturer, and an end-user certificate has to accompany the request before the allocation is granted. Tell us the memory you plan per node, whether you want the DPUs, the fabric the cluster uses and the end user, and request a quote.
