Exploring the Thermal Guidelines for Data Processing Environments
Liquid Cooling for DC's - Opportunities and Challenges
Classification: Basic/Intermediary
With the advent of increasing densities and the growing use of Artificial Intelligence and cryptocurrency mining, air cooling becomes a challenge and liquid cooling may be an answer. This presentation presents the basic concepts of liquid cooling and the challenges of implementing it.
Data Center Cooling for Dummies
As data centers become more complex and dense, understanding how heat is generated and managed in these environments is crucial. This presentation provides a clear and comprehensive overview of data center cooling basics, designed for a general audience. Topics include the primary sources of heat in data centers, such as IT equipment, power systems, cooling infrastructure, and environmental factors, and the crucial role that effective thermal management plays in maintaining reliability, performance, and energy efficiency. The session covers traditional air-cooling methods (CRAC, CRAH, fan walls), the advantages of free cooling, and the growing use of advanced liquid cooling technologies. Based on ASHRAE’s TC 9.9 guidelines and Datacom Series, the presentation raises awareness about data center cooling strategies.
