In Supermicro systems like the SYS-421GE-TNHR2-LCC, M.2 drives are typically mounted on the motherboard for fast storage in high-performance computing (HPC) and AI workloads, often cooled indirectly by DLC systems. To access the M.2 drive, you must:
Remove the motherboard tray from the chassis: This exposes the motherboard where M.2 slots reside.
Remove the air shroud from the motherboard tray: The shroud covers components for airflow or hybrid cooling, and its removal provides access to the M.2 slot.
Option D aligns with Supermicro’s design, as seen in manuals (e.g., SYS-420GP-TNAR), where M.2 drives are motherboard-mounted. A is incorrect since M.2 drives are serviceable; B (GPU tray) and C (fan housing) don’t house M.2 drives in this context. Supermicro’s DLC solutions prioritize motherboard accessibility, making D the correct procedure.
