Diagnostic Tool V1028b Updated -

Team: Hyperscale cloud provider (US East Coast) Problem: NVMe drives in 12% of storage nodes randomly dropped from PCIe bus under high write loads. Result: The updated diagnostic tool’s PCIe link training log decoders showed a subtle voltage sag on the 3.3V auxiliary rail, only when all 16 lanes were active. The v1028b’s new "power integrity" module traced it to a motherboard voltage regulator module overtemperature. Firmware patch to the VRM controller resolved the issue globally.
