Description
Accelerate your most demanding AI and HPC workloads with the Supermicro SYS-822GS-NB3RT, a high-density 8U GPU server built on the NVIDIA HGX B300 Blackwell Ultra platform. Powered by 8 NVIDIA Blackwell Ultra SXM GPUs delivering 2.3TB of HBM3e memory, dual Intel Xeon 6767P processors, and 3TB of DDR5-6400 ECC memory, this system is engineered for large-scale AI training, LLM reasoning, generative AI, scientific computing, and high-throughput inference workloads.
The SYS-822GS-NB3RT delivers exceptional GPU-to-GPU communication through 5th Generation NVLink and NVSwitch, providing 1.8 TB/s of bisection bandwidth across all eight GPUs — enabling seamless scaling for the largest model training runs. Eight integrated NVIDIA ConnectX-8 SuperNICs provide 800 Gb/s each, supporting InfiniBand XDR or dual 400 Gb/s Ethernet for high-performance AI fabric connectivity and multi-node clustering. An additional Mellanox ConnectX-6 Dx dual-port 100GbE QSFP56 NIC handles dedicated storage and management traffic, while onboard dual 10GbE Intel X710-AT2 ports and a dedicated GbE IPMI/BMC port provide comprehensive out-of-band management.
With 15.36TB of high-speed PCIe Gen5 NVMe storage across 8 hot-swap E1.S bays, dual 960GB M.2 boot drives, 6x redundant (3+3) 6.6kW Titanium-level power supplies, 2x PCIe 5.0 x16 FHHL expansion slots with support for NVIDIA BlueField-3 DPUs, the SYS-822GS-NB3RT provides a dense and scalable foundation for next-generation AI infrastructure. Backed by a 3-year onsite next-business-day warranty, this system is ready to deploy in production AI factories, neoclouds, and enterprise data centers.
