Supermicro Liquid Cooled Servers SDLCSA Question # 6 Topic 1 Discussion

Replacing an NVMe SSD in a Supermicro system like the SYS-421GE-TNHR2-LCC, which supports Direct Liquid Cooling, follows a standard procedure for hot-swappable drives in high-performance servers. The correct sequence, as outlined in Supermicro’s general server maintenance guides (e.g., for SYS-420 series or similar DLC-enabled systems), is:

Remove failed drive/drive carrier from chassis carriage: NVMe drives are housed in carriers for easy access and hot-swap capability, a feature emphasized in Supermicro’s DLC rack-scale solutions for minimizing downtime in AI/HPC workloads.

Remove failed drive from drive carrier: The carrier is opened to extract the faulty NVMe SSD.

Insert new drive into drive carrier: The replacement NVMe SSD is secured into the carrier.

Insert new drive/drive carrier into chassis carriage: The carrier is reinserted into the chassis, ensuring proper connection.Option D accurately reflects this logical order. Option A incorrectly involves DIMMs (memory modules), B mentions a fan (unrelated to NVMe replacement), and C involves a CPU (not part of the process). Supermicro’s DLC systems prioritize modularity and serviceability, making D the verified procedure.References:Supermicro NVMe SSD replacement guides (e.g., SYS-420GP-TNAR Manual), DLC solution serviceability features.
