    Time for new sustainability metrics? 

    Nicolas Dube, a datacenter efficiency strategist at HP, was recently the subject of a lengthy video interview where he gave an overview of new datacenter sustainability metrics in addition to Power Usage Effectiveness (PUE). These new sustainability metrics include the following:

    • Energy Reuse Effectiveness (ERE). A metric that is focused on heat reclamation.
    • Water Usage Efficiency (WUE). A site-specific metric that covers water usage in evaporative cooling.
    • Carbon Usage Effectiveness (CUE). A metric that tracks total carbon impact. This metric also includes the amount of carbon used by the electricity supplied to the datacenter.

    Nicolas pointed out that the datacenter industry is increasingly moving towards looking at the big picture when it comes to measuring environmental impact. Hence, the new metrics he discusses do a much better job of assessing this total impact.

    Can your datacenter be green if it’s in a city? 

    Data Centre

    You might be wondering whether or not to move your datacenter out of the city to the suburbs or completely out of an urban location – especially if you are trying to lower your carbon footprint and be as green as possible. After all, there is a point in time where having a datacenter in a big urban area becomes a serious disadvantage plus there is a limit to just how green you can be when located in heavily populated areas.

    Just consider some of the following issues:

    • Construction Costs. Permits, construction and labour costs in a major urban area will inevitably cost more than they would in a non-urban area. Likewise and once your datacenter is operational, it will probably cost significantly more to hire and retain employees in a major urban area than it would in a non-urban area.
    • Space Issues. In urban areas where space is at a premium, your ability to expand will likely be limited by space constraints or the high cost of additional space. Moreover, you can probably forget about most green initiatives like having large solar panels or a small wind farm on site.
    • Power Issues. If your datacenter is in a major urban area, chances are you are paying more per kilowatt than you would otherwise pay in an area that is less urbanized. The reason for this is simple: While the power grid in an urban area is huge, your datacenter is probably putting significant stress on that grid. Moreover, your ability to expand a datacenter in an urban area may be capped because you simply will not be able to get enough electric power to power an expanded facility while options for green or renewable power might be limited.
    • Disaster Concerns. Since your datacenter is already taxing the power grid that may be operating at near capacity, just one minor hiccup like a summer heat wave or a winter storm could mean that you would need to go on backup power for a lengthy period of time. Moreover, residential households will usually have priority over businesses when it comes to having their power restored.

    In other words and if you want to have the greenest and most cost efficient datacenter as possible, it might be time to consider relocating outside the city and to a more remote location. (Hat tip: Green Data Center News.)

    Is IT’s future really in the cloud 

    Blue sky thinking in the boardroomIt’s been said that the future of IT is in software and cloud computing but it is also forgotten that cloud computing software must run on physical hardware and ultimately on physical hardware located in datacenters. In fact, Gartner’s latest datacenter forecast (Forecast: Data Centres, Worldwide, 2010-2015) has new figures to show that IT datacenter sales are heading in just one direction and that is up.

    Just consider some of the following and latest projections from Gartner:

    • Worldwide datacenter hardware spending will rise 12.7% from $87.8 billion in 2010 to hit the $98.9 billion (£62 billion) level by the end of 2011. Moreover, datacenter hardware spending is forecasted to reach $106.4 billion in 2012 and $126.2 billion in 2015.
    • Datacenter spending growth in emerging economies such as the so-called BRIC countries (Brazil, Russia, India and China) will be balanced by continued weakness in both Japan and Western Europe.
    • Datacenter storage will be the major driver for growth. In fact and despite the fact that only a quarter of datacenter hardware spending is on storage, approximately half of the spending growth will be from the storage market.
    • The largest datacenter category (those with more than 500 racks) will see its share of spending rise from 20% in 2010 to 26% in 2015. This growth will be driven by cloud computing along with a move away from internal datacenters to external datacenters.

    In other words, the future of IT might very well be in datacenters and datacenter hardware to run all of those cloud computing applications.

    The environmental benefits of moving to the cloud

    A recent study, “Cloud Computing and Sustainability: The Environmental Benefits of Moving to the Cloud,” which was commissioned by Microsoft and conducted by Accenture and WSP, has found that companies running applications in the cloud can reduce their carbon emissions by 30% or more verses running the same applications on their own infrastructures.

    HP’s Project Moonshot 

    HP has recently unveiled Project Moonshot – a green datacenter initiative that is intended to reduce datacenter energy use by up to 89% through the sharing of storage, networking, management, power and cooling systems across thousands of servers.

    Do you know how much energy your datacenter uses? 

    Google LogoGoogle has recently revealed a closely guarded secret: How much electricity its datacenters use. In fact, Google has revealed that their entire operation:

    • Generated 1.46 million metric tons of carbon dioxide and consumed a total of 2,259,998 MWh in 2010.
    • Continuously uses enough electricity to power as many as 200,000 homes.
    • Continuously draws nearly 260 million watts, or roughly a quarter of a nuclear power plant’s output, with about 12.5 million watts going to power more than a billion searches a day.
    • Drew 25% of its energy from renewable fuels in 2010 and this figure should reach the 30% level this year and 35% next year.
    • Uses less than 1% of the total amount of electricity used by datacenters globally, which in turn accounts for 1.3% of total worldwide electricity usage.

    It’s worth noting that Google had received some flak from environmentalists and Greenpeace in particular – who previously gave the company an “F” for transparency on its Cool IT leaderboard. On the other hand and as the New York Times recently noted, some analysts had speculated that Google did not want to reveal information about electricity usage because it was embarrassing or it might allow competitors to decode just how efficient (and big) the company’s datacentre operations are.

    Nevertheless, Google’s disclosures about electricity usage could put pressure on other IT companies like Amazon, Apple, Facebook, Microsoft and Yahoo to reveal just how much electricity their datacentres are using along with the amount of carbon they produce.

    Can you cool your datacenter with sea water? 

    Atos think they can, according to Data Center Knowledge, who have reported that Helsinki Energy and IT services provider Academica have teamed up to build a unique datacentre for global IT outsourcer Atos that will use cold sea water for cooling while waste heat will be piped via a heat pump to heat Helsinki buildings along with residents’ domestic hot water.
