4U
Liquid-Cooled
Rack Configuration
The new liquid-cooled 4U NVIDIA HGX B200 8-GPU system features newly developed cold plates and advanced tubing design paired with the new 250kW coolant distribution unit (CDU) more than doubling the cooling capacity of the previous generation in the same 4U form factor.
The new architecture further enhances efficiency and serviceability of the predecessor that are designed for NVIDIA HGX H100/ H200 8-GPU.l the way up to 12 systems with 96 NVIDIA GPUs in a 52U rack.
Available in 42U, 48U or 52U configuration, the rack scale design with the new vertical coolant distribution manifolds (CDM) means that horizontal manifolds no longer occupy valuable rack units. This enables 8 systems, 64 NVIDIA Blackwell GPUs in a 42U rack and all the way up to 12 systems with 96 NVIDIA GPUs in a 52U rack.
