          Green is the hot topic these days, and the concept
     is having an impact on the way people think about
     datacenters. Companies around the world are
     announcing ways to save energy and reduce costs by
5   buying new hardware and services. Yet, there is little
     guidance on how you can take action to control energy
     costs. In the past, electricity has been treated as an
     overhead expense, like the cost of space. But with rising
     power costs and issues regarding reliability, supply, and
10  capacity, electricity requires its own specific strategy.
          Projects regarding performance optimization and
     cost reduction are a part of everyday best practices in
     nearly every area of business. So why not treat energy
     cost in the same way?
15      As Information Technologies (IT) pros, many of us
     make decisions about the configuration and setup of
     servers, the specifications on the equipment our
     organizations purchase, and the requirements for
     datacenter upgrades and construction. We even provide
20  early design input during application development. When
     it comes to these projects, we obviously have a golden
     opportunity to be green and influence the energy
     efficiency of any datacenter.
          The first part of any strategy is to know your current
25  energy usage. You need to know where your energy is
     used and by what specific equipment, as well as what
     usage is efficient and what is wasteful in the datacenter.
     Unfortunately, it's rare to find power-consumption
     metering in place that can break down usage to a level
30  where people can see the results of their actions. Most
     organizations typically only see a monthly power bill
     that rolls up consumption into an overall bottom line.
     This offers little incentive for saving energy since
     individuals never see the impact of their decisions, and
35  there is no way for them to prove that their changes
     have actually saved energy.
          One of the first issues people confront when
     considering a green datacenter initiative is whether they
     have executive support. For the purpose of the article, I
40  am going to assume the answer is "not yet." Executive
     support requires a serious commitment that provides
     resources and budget for your initiative. And while there
     is a lot of talk about green datacenters, the reality is
     that there is still often a lack of serious support at the
45  executive level. If you did already have such executive
     support, you would probably be running a green
     datacenter right now.
          Still, even assuming you are not getting the support
     you need, there is a great deal you can do to push your
50  green datacenter initiative forward. So how do you
     determine effective actions to take in achieving your
     goals? Fortunately, energy efficiency is not a new
     concept and there is a lot that IT pros can learn from
     other industries. [.]
55      Anyway, for whichever direction you choose,
     planning an energy efficiency program for your datacenter
     will require collaboration across groups in IT. Until
     recently, the typical approach to planning IT solutions
     has been to ignore power costs early on during the design
60  phase, focusing on the hardware and software being
     purchased, along with the labor and hosting costs of
     the solution. When power is buried in the overhead cost
     of running solutions in a datacenter, energy efficiency
     is a low priority. Exposing the actual power being
65  consumed by solutions is the first critical step in changing
     the behavior of your organization.

    The first part of any strategy is to know your current energy usage. You need to know where your energy is used and by what specific equipment, as well as what usage is efficient and what is wasteful in the datacenter. Unfortunately, it's rare to find power-consumption metering in place that can break down usage to a level where people can see the results of their actions. Most organizations typically only see a monthly power bill that rolls up consumption into an overall bottom line. This offers little incentive for saving energy since individuals never see the impact of their decisions, and there is no way for them to prove that their changes have actually saved energy.

     

    The author conveys in the 4th paragraph that there is no plausible method for gauging power consumption at data centre venues, which winds up being problematic as the only proof of how much energy was needed to run comes in the form of a singular utility bill, which does little to help track effective measures.

     

    Ha a preocupação com a falta de meios de medir energia durante as atividades cotidianas do data center, consoante o 4° parágrafo.

    Complementando!

    A - gives advice on measures to be taken by organizations and regrets that the energy-saving efforts of datacenter workers cannot be verified.

    CERTO.

    No parágrafo 4, o autor lista conselhos úteis a respeito do consumo de energia atual da empresa: 

    • know where your energy is used (l. 25): “saber onde a energia é usada
    • and by what specific equipment (l. 26)”: “por qual equipamento específico [ela é usada]”
    • what usage is efficient (l. 26-27): “o que é uso eficiente”
    • what is wasteful (l. 27)”: “o que é desperdício”

    Além disso, ele lamenta que não haja uma medição que mostre às pessoas o consumo resultante de cada uma de suas ações

    Logo, é correto afirmar que o objetivo do texto é dar conselhos sobre medidas a serem adotadas pelas empresas e lamentar que os esforços para economizar energia pelos funcionários do datacenter não possam ser verificados.

    ===

    B - warns about what is wasteful in corporate datacenters and criticizes employees for not engaging in energy-saving programs.

    ERRADO.

    No parágrafo 4, o autor relaciona alguns conselhos úteis a respeito do consumo de energia atual da empresa, dentre os quais está identificar:

    • “o que é uso eficiente” (what usage is efficient - l. 26-27);
    • “o que é desperdício” (what is wasteful - l. 27)”.

    No entanto, ao fazer isso, ele apenas ressalta que não há estímulo para que as pessoas economizem energia já que elas não veem os impactos de suas ações:

    Logo, o autor NÃO adverte sobre o que é ou não desperdício e nem faz qualquer tipo de crítica aos procedimentos dos funcionários. 

    ===

    C - encourages the use of power-consumption metering in datacenters and claims that this is the only possible way of saving energy in an office.

    ERRADO.

    No parágrafo 4, o autor lamenta que não haja uma medição que mostre às pessoas o consumo resultante de cada uma de suas ações  

    Entretanto, ao fazer isso, ele apenas constata uma realidade dos datacenters.

    ===

    D - reveals that most organizations do not stimulate the reduction in energy consumption and blames office workers for wasting energy in datacenters.

    ERRADO.

    No parágrafo 4, o autor ressalta que não há estímulo para que as pessoas economizem energia já que elas não veem os impactos de suas ações, mas não chega a atribuir essa falta de estímulo diretamente às empresas

    Além disso, ele NÃO culpa os funcionários por gastarem energia nos datacenters. 

    ===

    E - describes the importance of monthly power bills for energy-efficient programs and justifies why this strategy has been adopted by most organizations.

    ERRADO.

    No parágrafo 4, o autor afirma que algumas organizações apenas veem o consumo geral de energia na linha inferior da conta:

    Entretanto, ao fazer isso, ele apenas constata uma realidade dos datacenters e não menciona as ações de outras empresas.

    Logo, o autor NÃO descreve a importância das contas de energia elétrica para os programas de eficiência energética e e nem justifica a adoção dessas estratégias por outras empresas.
