Monitoring gives diffi cult explanations
There is no single explanation for different levels of monitoring of energy effi ciency and carbon emission in these data centers:
» The most developed data center markets – Eastern United States, United Kingdom and West Coast United States are all in the top fi ve for monitoring energy effi ciency and the protracted twists and turns of the UK Carbon Reduction Commitment means organisations have had some time to prepare themselves for the close monitoring of carbon
» The position of China high on both lists is due to the extent of both new facility development and the deployment within these of cutting- edge technologies
» The monitoring of effi ciency bears greater relation to perceptions of energy costs than to fears of legislation. Recent carbon taxation legislation in Australia does not appear to have created urgency in that market, probably because it will be directed at heavy carbon generators.
» The bottom of both lists is dominated by developing markets – these are those where the driver of maintaining availability at all costs is strongest
Size matters
Monitoring activity increases quite simply with greater energy consumption and there is a direct correlative
monitoring, both of effi ciency and of carbon emission on a continuous basis:

The 5 kilowatt rule
This was fi rst published in April 2010 based on event based research undertaken by DCD over 4 years
Once a datacenter’s power demand per rack passes over 5kW priorities change. Levels of concern about operating and funding the datacenter will rise as will adoption of ‘whole of datacenter’ strategies. The rate of increase in power demand will lessen considerably (although moving from 6 kW/rack to 8 kW/rack is less of a seismic shift as moving to 6 from 4). Precision cooling, automation, monitoring, most technologies with
