Conventional methods for specifying data center density are ambiguous and misleading.
Describing data center density using Watts / ft2 or Watts / m2 is not sufficient to determine
power or cooling compatibility with high density computing loads like blade servers.
Historically there is no clear standard way of specifying data centers to achieve predictable
behavior with high density loads. An appropriate specification for data center density
should assure compatibility with anticipated high density loads, provide unambiguous
instruction for design and installation of power and cooling equipment, prevent oversizing,
and maximize electrical efficiency. This paper describes the science and practical
application of an improved method for the specification of power and cooling infrastructure
for data centers.
