Data Center Airflow Management Basics: Comparing Containment Systems
In the past decade, many companies have become aware of the advantages of data center airflow management practices that include containment systems. It is also now well understood that as the average heat load per cabinet rises, simply arranging cabinets in a traditional open hot aisle/cold aisle configuration is not an effective approach. Industry associations have considered indirect and direct liquid cooling as possible solutions for high density applications, but using a containment system with perimeter cooling is still a very capable solution for today’s average rack densities and the anticipated densities over the next decade. Furthermore, containment systems support retrofit from hot aisle/cold aisle, economizer applications and free air cooling.
This white paper, by Chatsworth Products (CPI), examines and compares three data center containment systems and demonstrates that there are important differences to consider that distinguish one system over the others. It will help you to determine the best
containment option for your data center requirements and your business goals.
Data Center Airflow Management Basics: Economics of Containment Systems
Based on data extrapolated in the June 2016 United States Data Center Energy Usage Report1, average individual rack density for a rack full of servers will range between 4 kW and 11 kW by 2020. It is important to recognize that as rack densities exceed 4 kW, traditional hot aisle/cold aisle configurations become less effective. Hot air recirculates over and through the cabinet, causing hot spots, which is typically met with the costly oversupply of cold air.
You can reliably dissipate the heat in these racks by utilizing a containment system that effectively isolates hot air from cold air and directs hot exhaust airflow away from equipment and back to air handlers. More importantly, careful airflow management through the use of containment systems allows several cooling system adjustments that can reduce overall cooling energy costs at any rack density.
This white paper by Chatsworth Products (CPI) examines how implementing a complete containment system contributes to overall reduced cooling system energy costs in the data center and prepares your site for an anticipated increase in rack density.
Considerations for Intelligent Power Management within High-Density Deployments
As data centers deploy virtualization and consolidate equipment for more efficient computing, the average rack power density is constantly rising. While an average cabinet supported 3 - 4 kW a few years ago, today that power load is considered in low-density environments. It is certainly not uncommon to have cabinets drawing 9 - 15 kW and in several cases, even higher than that.
This paper discusses the electrical, physical and management considerations for effective cabinet-level power management within such high-density scenarios. It presents six key considerations when deploying intelligent power distribution units into high-density cabinets and also covers the management of cost and security associated with the deployment of intelligent PDUs.
Data Center Optimization: A Guide to Creating Better Efficiency and Improving Rack Heat Density in Air Cooled Facilities
The modern data center has changed. There are new demands around cloud computing, big data and infrastructure efficiency. With private cloud technologies and the rapid growth in data leading the way within many technological categories (the Internet of Things), working with the right data center optimization technologies has never been more important.
IT administrators must understand how to control their resources, align with the business and create greater levels of efficiency.
In this white paper, we explore new concepts around emerging data center demand, where energy efficiency and cooling optimization fit in and modern best practices around your data center.
How Cabinet Perforation Impacts Airflow
When choosing a cabinet door for your data center it is essential to ask yourself what level of perforation will be needed. Opinions on this subject are extensive, and some experts will tell you that for high-density heat loads of 30 kW and above, you need 80% perforation, while others will say only 64% perforation is needed. Data center technology develops at a rapid pace and every day new discoveries are uncovered, which is why there is more to this question than just a single number.
This study will give you the tools to identify what level of cabinet perforation best suits your specific application and will show that for a large cross sectional area, using a perforation of 64% does not impact airflow and there is no loss in performance even at extreme density loads of 30 kW and above.
