Thermal Zone Mapping: Data Center Design and Assessment Automated Visualization Tool for Thermal Metric Analysis
Keywords: Data Center, Computational Fluid Dynamics (CFD), Thermal Metrics
Thermal Zone Mapping (TZM) is a visualization tool developed to present in graphical format high-level thermal metrics used for data center assesments. This tool extracts data from computational fluid dynamic models and generates metrics which are then post-processed and visualized in two and three-dimensional data center space. Among other things, output from the tool can be used to optimize the placement of equipment in a data center, investigate failure scenarios and insure that a proper cooling solution has been achieved . Computational Fluid Dynamics (CFD) is increasingly being used to provide thermal assessments of data center environments. A typical data center service utilizes off-the-shelf CFD software tools to evaluate the thermal performance of data centers. Visualization tools available within the software that allow visualization of low-level parameters like temperature, air velocity and pressure are used to perform this evaluation. However, visualization of low-level parameters can often mask critical attributes of fluid flow and heat transfer. Much work has been done in recent years on the development of higher order metrics to assist in the evaluation of numerical results in particlar and environmental data in genreal. Two such metrics are the Supply Heat Index (SHI) and the Thermal Correlation Index (TCI). Both have been disclosed in previous publications. This presentation will describe custom software tools that have been developed to take raw data from CFD tools, automatically generate 2D and/or 3D data center geometry, calculate a given higher-level metric in 2D and/or 3D space and display the information in a format that is easily understood by the user.
