Guidelines for Specification of Data Center Power Density
Introduction The specification of operating power density for data centers and server rooms is a growing
challenge for IT professionals. Specifying data centers at the traditional densities of 40-80
Watts / ft2 (430 - 861 Watts / m2) will result in the inability to reliably deploy the latest
generations of IT equipment. Specifying data centers at the 600-1000 Watts / ft2 ( 6458 –
10764 Watts / m2) operating density of the latest generations of high density IT equipment will
result in data centers that stress the limits of data center power and cooling technology and
result in extraordinary capital costs as well as low electrical operating efficiencies.
The density planning problem is further exacerbated by the need to design a data cent
