Dual Xeon 8570 AI server with eight H200 GPUs

This 4U rack server pairs two Intel Xeon Platinum 8570 processors, each with 56 cores at 2.10 GHz, with an NVIDIA HGX H200 platform containing eight GPUs. It ships with 3 TB of DDR5-5600 memory across 32 slots and two 960 GB M.2 NVMe SSDs for the operating system. The system targets large-scale AI training and high-performance computing workloads.

Suited for AI training clusters needing dense GPU

The eight H200 GPUs provide 141 GB of memory each for large-model training. Networking includes eight single 400 G NDR/ETH OSFP ports and one dual 200 G NDR200/ETH QSFP112 port for high-speed cluster interconnects. Buyers who need only CPU compute, fewer GPUs, or slower interconnects should consider smaller configurations.

Requires 4U rack space and high-power infrastructure

Eight 5250 W titanium-level power supplies deliver redundant power for the full GPU complement. Four hot-swap 8 cm fans cool the chassis, which operates between 10 °C and 35 °C. Eight front 2.5-inch NVMe bays and two M.2 slots remain available for additional storage expansion.

Questions about this item

What power infrastructure is required for the four 5250 W Titanium power supplies?

The system ships with four 5250 W Titanium-level power supplies; plan for matching PDU outlets and circuit capacity to support the combined draw.

Will the eight H200 GPUs share the PCIe lanes with the front 2.5-inch NVMe bays?

The eight H200 GPUs use SXM5 sockets on the HGX baseboard, while the eight front hot-swap 2.5-inch NVMe bays connect through separate CPU-attached lanes, so they do not contend for the same PCIe resources.

How can I confirm the 3 TB of DDR5-5600 is running at the rated speed after installation?

Check the BIOS memory information page or run a tool such as dmidecode; both will show each of the 32 RDIMM slots populated at 5600 MT/s when the system is configured for 1 DPC operation.
