You are validating the hardware architecture for an AI solution.

The correct answer is B. The HPE ProLiant Compute DL384 Gen12 is an AI-optimized server platform built around NVIDIA Grace Hopper Superchip architecture. In this class of design, the CPU/GPU complex and high-bandwidth memory are integrated as part of the Superchip module rather than being expanded like conventional DIMM-based system memory. The HPE DL384 Gen12 data sheet describes the platform as using NVIDIA GH200 NVL2 Superchips and highlights coherent memory and memory bandwidth characteristics, which is exactly why the memory configuration is treated as tied to the Superchip selection. Option A is incorrect because the DL384 Gen12 architecture is not upgraded by freely adding more GB200 accelerators; it is based on a defined Grace Hopper Superchip platform. Option C is incorrect because EDSFF drive support is a platform/backplane architecture consideration, not simply a RAID-controller dependency. Option D is also not the governing rule for 400Gb NIC support. Reference/topics: AI server architecture, DL384 Gen12, NVIDIA GH200/NVL2, Superchip memory architecture, hardware validation.
