Thermal State Model Construction Method for Data Centers Based on Bayesian Inference from Measurements
As data centers continue to grow in scale and computational density
thermal management has become one of the critical factors affecting their energy efficiency and reliability. Building accurate thermal models is essential for implementing effective thermal management. Aiming at the modeling problem for thermal state of data centers
the construction mechanism of thermal state model for Bayesian data center based on real-time temperature measurement is proposed. First
based on the thermodynamic propagation structure of data centers
a dynamic thermal model is proposed to describe the central processing unit
server chassis
and environmental temperature
in order to characterize the thermal state of data centers over time. Then
to address the strong nonlinearity and prior defects in the thermodynamic mechanism model of data centers
a layered adaptive importance sampling technique based on Bayesian inference is developed. Simulation results demonstrate that the proposed method achieves high-accuracy modeling of thermal state models for data centers and exhibits high applicability under various prior settings.
