DCBBS·DLC-2 Liquid Cooling Integration, Supporting 1,152 GPUs and 331TB HBM4 per Scalable Unit
As demand for AI acceleration computing surges, Supermicro has begun shipping NVIDIA Vera Rubin NVL72 racks. This product integrates Data Center Building Block Solution (DCBBS) and direct liquid cooling technology stack (DLC-2), and is supplied with the entire cooling system from cold plates to cooling towers pre-validated.
Supermicro announced on the 29th that it has commenced shipments of NVIDIA Vera Rubin NVL72 racks.
Charles Liang, President and CEO of Supermicro, stated, "Customers can now order scalable units and receive systems with end-to-end integration completed, ready for immediate deployment in commercial environments," and added, "Supermicro's DLC-2 technology enables us to provide an integrated solution for the NVIDIA Vera Rubin platform."
The NVIDIA Vera Rubin NVL72 rack integrates 72 NVIDIA Rubin GPUs and 36 Vera CPUs in a single liquid-cooled rack.
It consists of 18 1U computing trays and 9 sixth-generation NVLink switch trays, with scale-up bandwidth reaching 216TB/s.
Per rack, it supports 20.7TB of HBM4 memory and up to 54TB of maximum LPDDR5X memory.
Liquid cooling is a fundamental design requirement for the NVIDIA Vera Rubin platform, as air cooling alone has limitations in handling heat as AI computational density increases.
Supermicro tests and validates all racks with the complete cooling system integrated, reducing the interval between on-site deployment and operational startup.
Liquid cooling components include △cold plates △manifolds △hose kits △in-row cooling distribution units (CDU) △in-rack CDU △rear door heat exchangers △facility cooling towers.
In-row CDU supports cooling capacity of 1.8MW per CDU and is configured in N+1 redundancy.
Supermicro provides DCBBS blueprints for power scales ranging from 5MW to gigawatt-class.
On a single scalable unit basis, it supports 1,152 GPUs and 331TB of HBM4 memory across 16 computing racks, with balanced configuration of cooling, power, storage, and networking.
The entire project lifecycle from on-site facility survey and design, solution integration, L11·L12 testing, on-site deployment, and post-deployment support is managed by a single dedicated team.
Supermicro performs all stages directly, from node machine design through large-scale manufacturing of liquid-cooled racks to on-site cluster deployment based on NVIDIA reference architecture.
