Model SYS-422GS-NBRT-LCC
Front-I/O DLC-2 system enabling up to 96 Blackwell GPUs in a single rack.
This 4U liquid-cooled Supermicro server runs an NVIDIA HGX B200 8-GPU board with direct-to-chip cold plates. Eight systems with 64 GPUs fit in a 42U rack, or twelve systems with 96 GPUs in a 52U rack.
Supermicro's direct liquid cooling captures most system heat at the source, cutting data center power by up to 40% and running at noise levels as low as 50 dB.
1.44 TB of GPU memory with NVLink and NVSwitch.
Cold plates on CPUs and GPUs; up to 40% data center power savings.
12 systems in a 52U rack, or 64 GPUs in 42U.
Up to 86 cores and 350 W per CPU.
8× x16 LP for networking plus 2× x16 FHHL.
4× 6.6 kW Titanium (2+2).
