Human and management errors are the root cause of most failures and energy wastage in data centres. Learning curves for organisations and operators have been developed for several industries, such as nuclear power, space travel, chemical, aeronautical, medical. Operator depth of experience can be improved through effective training, thereby decreasing failure rates, optimising energy performance and reducing staff turnover. The main issues are management complacency, inter-team communication, air management ownership and metrics, risk awareness, energy awareness, over reliance on procedures and on humans to do the “right thing”. By addressing the human element, significant TCO reductions have been achieved.
Beth Whitehead, Sustainability Engineer at OI, describes how the energy consumption, energy mix and number of servers provide the biggest opportunity for environmental impact savings in the data centre.
Reflecting on Experience
There is always pressure at the end of a project to reduce commissioning time. However, the interdependency dimensions of any project are financial, time and quality. Each one of these dimensions affects the other dimensions.
If you shorten the programme time, then it will either cost more or the quality (of tests / commissioning) will be compromised.
If you try to reduce the cost of it (cutting corners), again the quality will be compromised and you will certainly have delays.
If you compromised the quality (why would you?) it would cost less and shorten your programme.
Bearing in mind that commissioning is proving that what has been designed will actually work in practice, in whose interest is it to compromise commissioning?
