data center measurement
DESCRIPTION
Data Center Measurement - Building An ROI Baseline Establishing a baseline measurement of your data center is an important first step in developing a meaningful ROI for any data center project. The cost of energy has recently exceeded the cost of IT equipment; understanding your energy footprint in terms of power consumption and cooling demand has become an important management tool. to view the recorded webinar presentation, please visit http://www.42u.com/measurement-techniques-webinar.htmTRANSCRIPT
