McKinsey & Company, a management consulting company, has released a report entitled "Data centers: How to cut carbon emissions and costs." The report provides a detailed overview of data center trends, complete with interesting facts: the carbon footprint of global data center operations equals that of the Netherlands or Argentina; and data center costs are rising almost four times faster than overall IT costs. A bit on the technical side, but a good read nonetheless.
From the report:
"Our work suggests that companies can double the energy efficiency of their data centers through more disciplined management, reducing both costs and greenhouse gas emissions. In particular, companies need to manage technology assets more aggressively so existing servers can work at much higher utilization levels; they also need to improve forecasting of how business demand drives application, server, and data center–facility capacity so they can curb unnecessary capital and operating spending."
The study features graphs and case studies. Unsurprisingly, the term "virtualization" is right there in the discussion of how to improve data center effectiveness. The authors also stress the importance of government regulation, strict metrics, and the role of the CIO.
