NVIDIA HGX Rubin NVL8 8-GPU Server (Supermicro SYS-222GS-R2BT-ALC)
NVIDIA HGX Rubin NVL8 8-GPU server — Supermicro SYS-222GS-R2BT-ALC in a 2U direct-liquid-cooled chassis, offered for pre-order allocation as part of an integrated rack.
8-GPU NVIDIA HGX Rubin NVL8 server on the Supermicro SYS-222GS-R2BT-ALC platform. Cisco’s published datasheet identifies this Supermicro model and describes a 2U MGX system with blind-mate power and coolant connections, delivered as part of an integrated rack. The eight-GPU NVLink domain is within the node; stacking nodes does not make the rack a single NVL72 domain. There is no air-cooled option. Supermicro offers a liquid-to-air sidecar for facilities without water loops; the server itself remains liquid-cooled. Cisco lists availability in October 2026, while this listing is a pre-order allocation inquiry. Configuration and availability confirmed at quote.
