TL;DR: In this article, the authors developed a generalized testing methodology in which IT fans' internal and external impedance effects are collapsed into a single curve (i.e., flow curve), which can give accurate flow rate predictions of the IT equipment based on RPM logging.

TL;DR: In this article, the authors used a full physics-based CFD model to simulate/predict the measured data and showed that the model can be used to predict the real-time flow rate of servers at known RPM.

TL;DR: In this article, a facility-level DC cooling failure experiment is run and analyzed, where an airside cooling failure is introduced to the facility during two different cooling set points as well as in open and contained environments.

TL;DR: In this article, the authors report experimental and numerical testing performed to characterize the operation and reliability of the open compute (OC) storage system in contained environment from server to aisle levels.

TL;DR: In this article, the authors present a novel control scheme in which the control of the cooling system is split into two control loops to maximize efficiency, the first control loop is the cooling fluid which is driven by the temperature from the physically lower server to ensure the correct supply air temperature.
