Many companies think they are reaching the power or cooling capacity of their facility due to hot spots or other cooling issues. In most cases there is excess cooling and air volume but it is not being delivered where it is needed. Common questions we are asked,

‘What is the life expectancy of my current facility?’,
‘How soon do I need to start planning for an expansion or new data centre?’
‘Are there changes I can make to my existing facility to extend its life?’
‘What are the greatest energy saving steps I can take?’


By conducting an audit and modeling your data center we are able to provide the answers you need without incurring major capital investment. Computational Fluid Dynamics is a modeling tool we use to provide the details on the air flow management of your data centre and identify problems. Once a baseline model is created we can perform the ‘what if’ exercises to test alternative solutions and decide which one is best before a large amount of money is spent on solutions that may not work.

CFD modeling takes into account all aspects of the data centre: number of racks, equipment configurations, heat load, dimensions of the facility, attributes of the CRAC units, etc. Based on sophisticated mathematical algorithms we are able to provide you with a view of the future, answering the key questions of life expectancy, ability to handle additional load and recommendations for improved air management.

Modelling will provide a detailed analysis of the current configurations including evaluation of airflows and thermal loads in the data center, and identify if the airflow rate and/or cooling capacites are not adequate or properly configured. The analysis includes:

  • a  comprehensive cooling audit report with detailed analysis of CRAC, rack and tile airflow performance in HTML form that can be imported into a spreadsheet or powerpoint presentation and shared with others to help make critical decisions on how to set up a new data center or revamp an existing site to alleviate cooling problems
  • colour coded thermal mapping of all rack temperatures in the data center to instantly identify hot servers and verify rack inlet temperatures against ASHRAE thermal guidelines for maximum allowable temperature
  •  visual representation of room airflow patterns and temperature distribution, plenum airflow patterns and pressure distribution, and flow distribution through tiles
  • ability to run multiple scenarios of possible situations including impact of CRAC failure, increased heat load, impact of hot or cold aisle containment or room redesign.
