I attended the 2009 IT Roadmap Conference in Atlanta, Georgia this week and sat in on the presentation by Johna Till Johnson of Nemertes Research, entitled ‚ÄúBuilding a Resilient Dynamic Data Center.‚Äù The presentation was a summary of hundreds of hours of discussions with data center operators and enterprises with data centers.
The information was summarized and presented in the framework of trends- from old to new. Of the data centers investigated, the ages were approximately 18 years old and the youngest around eight years old.
Beginning with the older sites, this vintage data center was built favoring reliability over responsiveness to change or business agility. The rate of growth within the data center was low, HVAC and power were relatively static, and there was little network infrastructure.
