The following are some recent articles in the context of data center sustainability, that I’ve found interesting. Have a look. Growth Seen for Global Green Data Center and Building Energy Software Markets http://www.greenrealestatenews.com/idgreendatacenters.html The global green data Center market is expected to grow from $23.41 billion in 2014 to $95.66 billion by the end of…
The challenge in using green energy alternatives such as wind or solar power in data centers is power density.¬†¬† Data centers consume a lot of power with respect to their physical footprint, so they need very large solar arrays or large wind turbine farms to generate the necessary power for the facility.¬† Consequently, the amount of time required to reach the positive ROI point with the solar or wind power equipment is typically quite long.¬† This economic detail is often the inflection point for deciding whether to apply green energy alternatives in the data center plan.
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.
Microsoft Windows running on a mainframe? Could this be the greatest abomination since the Labradoodle (before you Labradoodle owners out there skewer me, I’m sorry but the Labrador Retriever is such a wonderful dog and to corrupt this fine breed with Poodle blood is a bane to me)? Anyway, this week’s Network World magazine carries…
Morgan Stanley plans to power their new data center in Scotland with a new generation of turbine generators called the Transverse Horizontal Axis Water Turbine (THAWT). The $400M data center will require 150MW of power. It will be powered initially from the utility grid but later transitioned to power generated by the underwater turbines of the THAWT device.
In the Data Center World keynote address in Orlando, Florida today, four distinguished panelists shared the results of Data Center Institute (DCI) research on the impact of the economic downturn on the data center.¬† This research was conducted over a number of months through surveys of enterprise data centers across the AFCOM membership.
There are four clear indicators that emerged from this research:
As a bit of background and at the risk of stating the obvious, let’s quickly review some basics about energy efficiency and the Data Center. It has been estimated that on average, electricity costs account for over 40% of data center operational expenses. In 2006, American data centers consumed more electricity than all the televisions in America. The cost to power a typical server now exceeds the cost to buy it, when viewed over a three-year horizon. Data Centers typically operate more than 2.5 times the cooling capacity needed to maintain the IT equipment. On average, less than 50% of the cool air in a chilled-air data center actually makes it to the IT equipment.
Those first few points are likely already well understood by the reader, or are at least consistent with other similar metrics quoted in the Green dialogue. The last one, which speaks to the challenges of efficiently cooling IT equipment, is what I’d like to talk about in more depth.
We’ve discussed the topic of data center energy management in numerous posts, and we’ve talked about a Green Data Center Maturity Model. If the topic of energy efficiency in the data center is of interest to you (and it should be) I’d like to recommend an excellent resource for you. Cisco is conducting a webinar…
