Cooling Strategies for Ultra-High Density Racks and Blade Servers


Rack power of 10 kW per rack or more can result from the deployment of high density equipment such as blade servers. This creates difficult cooling challenges in a data center environment where the industry average rack power consumption is under 2 kW. This white paper discusses:

  • A background and explanation of power density
  • Actual power density values of current and new data centers
  • Practical approaches to achieving high density
  • Logical and practical strategies for deploying high density computing.
