The eight-way XD685 in its NVIDIA HGX H200 configuration, the only one of the four HPE offers in both air-cooled and liquid-cooled form: 6U for air with accelerator kit S3P89A, 5U for direct liquid cooling with S4X53A. Two fifth-generation AMD EPYC processors drive it, from 32 to 96 cores and 280 to 400 W, across 24 DIMM slots with twelve channels per socket and up to 6 TB of DDR5-6400. Storage is eight EDSFF NVMe E3.S drives, or twelve with a storage controller, plus RAID-1 M.2 boot. No chassis part number is recorded because two apply depending on cooling, S4Q28A for air and S4R96A for liquid. HPE publishes no system power draw for the XD685, only twelve 3,000 W Titanium supplies with ten deployable, so nothing is summed here; the compute figures are NVIDIA's for the HGX H200 baseboard rather than an HPE claim.
