Role of CFD Analysis in Optimizing Data Centre Performance
The data center sector is undergoing a significant transformation, fueled by the rising demand for high-performance computing (HPC) and artificial intelligence (AI) applications, which is pushing computing densities to new heights.
This escalation in power density greatly amplifies the cooling demands necessary to avert overheating and potential downtime. In response to these challenges, data centers are increasingly adopting hybrid cooling systems that integrate traditional air cooling with liquid cooling, proving to be an effective approach for managing these heightened thermal loads.
Hybrid cooling solutions enable data center operators to manage these elevated temperatures without the need for complete retrofitting of current facilities, facilitating a gradual and cost-efficient method for incorporating liquid cooling tailored to specific high-heat applications.
Objective of conducting CFD analysis for Immersion cooled data center
Our Client manages a diverse portfolio of innovative IT companies operating in 70 countries across Europe, the Middle East, and Africa. They provide a range of services including managed IT services and consultancy, system integration, cloud and data center solutions, software and hardware offerings, as well as technology distribution.
Scope of this contract is to create a 3D CAD model in accordance with the requirements of computational fluid dynamics (CFD) analysis, develop an appropriate CFD mesh, and carry out a thorough CFD analysis for a hybrid-cooled data center featuring 16 close control air conditioning units (CCUs), including two backup units. The CFD analysis was performed using five distinct redundancy configurations, and a detailed CFD analysis report, encompassing observations, conclusions, and recommendations, was provided as the final output.
CFD analysis results
Maintaining efficient airflow in data center racks is crucial for ensuring optimal equipment performance and extending the lifespan of servers. Within the current data center, there are a total of 18 CCU units, with 2 of them serving as redundant units. These 16 CCU units work together to distribute the airflow across 16 rows of racks. Through CFD analysis, we have examined various combinations of CCU operation, and the results indicate that the air flow within the data center is deemed satisfactory.
CFD Results: Temperature in the data center
Through CFD analysis, we have examined various combinations of CCU operation, and the results indicate that the air flow within the data center is deemed satisfactory and maximum temperature within the data center unit is 29 Degree Celsius. Hence it was concluded that the proposed cooling design is adequate.
Conclusions drawn from CFD analysis
The results of the CFD analysis indicate that the cooling system implemented for this data centre is adequate, and there is a sufficient level of redundancy in place.
