Cooling Audit for Identifying Potential Cooling Problems in Data Centers
The compaction of Information Technology equipment and simultaneous increases in processor power consumption are creating challenges for data center managers in ensuring adequate distribution of cool air, removal of hot air and sufficient cooling capacity. This paper provides a checklist for assessing potential problems that can adversely affect the cooling environment within a data center.

Choosing Between Room, Row, and Rack-based Cooling for Data Centers
Latest generation high density and variable density IT equipment create conditions that traditional data center cooling was never intended to address, resulting in cooling systems that are oversized, inefficient, and unpredictable. Room, row, and rack-based cooling methods have been developed to address these problems. This paper describes these improved cooling methods and provides guidance on when to use each type for most next generation data centers.

Cooling Strategies for IT Wiring Closets and Small Rooms
Cooling for IT wiring closets is rarely planned and typically only implemented after failures or overheating occur. Historically, no clear standard exists for specifying sufficient cooling to achieve predictable behavior within wiring closets. An appropriate specification for cooling IT wiring closets should assure compatibility with anticipated loads, provide unambiguous instruction for design and installation of cooling equipment, prevent oversizing, maximize electrical efficiency, and be flexible enough to work in various shapes and types of closets. This paper describes the science and practical application of an improved method for the specification of cooling for wiring closets.

Implementing Hot and Cold Air Containment in Data Centers
Containment solutions can eliminate hot spots and provide energy savings over traditional uncontained data center designs. The best containment solution for an existing facility will depend on the constraints of the facility. While ducted hot aisle containment is preferred for highest efficiency, cold aisle containment tends to be easier and more cost effective for facilities with existing raised floor air distribution. This paper investigates the constraints, reviews all available containment methods, and provides recommendations for determining the best containment approach.

Cooling Options for Rack Equipment with Side-to-Side Airflow
Equipment with side-to-side airflow presents special cooling challenges in the modern data center. Common rack enclosures and rack layouts are fundamentally incompatible with side-to-side cooling, resulting in equipment that receives supply air of excessive temperature. This paper describes the problem along with several side-effects that are not generally appreciated. Various solutions to the problem are described along with their costs and benefits.

Impact of High Density Hot Aisles on IT Personnel Work Conditions
The use of modern enclosed hot aisles to address increasing power densities in the data center has brought into question the suitability of working conditions in these hot aisle environments. In this paper, it is determined that the additional heat stress imposed by such high density IT environments is of minimal concern.

Impact of Hot and Cold Aisle Containment on Data Center Temperature and Efficiency
Both hot-air and cold-air containment can improve the predictability and efficiency of traditional data center cooling systems. While both approaches minimize the mixing of hot and cold air, there are practical differences in implementation and operation that have significant consequences on work environment conditions, PUE, and economizer mode hours. The choice of hot-aisle containment over cold-aisle containment can save 43% in annual cooling system energy cost, corresponding to a 15% reduction in annualized PUE. This paper examines both methodologies and highlights the reasons why hot-aisle containment emerges as the preferred best practice for new data centers.

The Use of Ceiling-Ducted Air Containment in Data Centers
Ducting hot IT-equipment exhaust to a drop ceiling can be an effective air management strategy, improving the reliability and energy efficiency of a data center. Typical approaches include ducting either individual racks or entire hot aisles and may be passive (ducting only) or active (include fans). This paper examines available ducting options and explains how such systems should be deployed and operated. Practical cooling limits are established and best-practice recommendations are provided.

How to Fix Hot Spots in the Data Center
Data center operators take a variety of actions to eliminate hot spots. Some of these actions result in short term fixes but may come with an energy penalty and some actions may even create more hot spots. Airflow management is an easy and cost effective way to permanently eliminate hot spots while saving energy and can avoid the capital expense of adding more cooling units. This paper describes the root cause of hot spots, recommends methods to identify them, reviews the typical actions taken, and provides the best practices to eliminate them.
