Rack-Inlet Thermal Excursions Under Comparable IT Load
Why it is hard: A warm rack-inlet reading can reflect load, airflow distribution, containment, pressure, cooling supply, sensor placement, or transient operations. It does not directly measure component temperature or prove hardware stress.
What Grayson analyzes: A prepared file containing rack-inlet temperatures, rack IT power, cold-aisle differential pressure, CRAH supply temperature, load bands, operating-period labels, and event context.
Ask Grayson: “Compare the two excursion windows with baseline periods at the same rack-load band. Which recorded signal changes first, and how long does each deviation persist?”
Outcome: Focus inspection on the affected time windows, probes, containment, perforated tiles, obstructions, and cooling context.
