Data centres are the foundation on which the modern
digital world has been built.
Their importance is highlighted by the fact that there
is a scarcely a corner of our society they haven’t
touched.
Furthermore, the growing use of mobile terminal
devices and the increasing amount of available
data means that data centres will continue to
grow in size and scale for the foreseeable future.
But large-scale data centres of cloud and co-location
providers consume a huge amount of energy - in the
double-digit megawatt range. It’s not surprising,
therefore, that data centres around the world are
collectively responsible for a growing share of global
CO2 emissions.
In fact, it is predicted that the IT industry’s share of
worldwide CO2 emissions will virtually double in less
than 20 years, from 1.3% in 2002 to 2.3% in 2020
(source: The Global e-Sustainability Initiative).
Reducing greenhouse gas emissions is therefore an
imperative for the industry, and of course by increasing
energy efficiency and therefore reducing CO2 emissions,
data centre operators should be able to significantly
reduce their energy costs. Together, these twin outcomes
can provide a competitive advantage for companies with
a Green IT Policy as Google and Apple and others are
demonstrating.
Measuring the efficiency of the data centre can be done
through a series of metrics, the most important of which
include energy consumption, CO2 emissions and also
sustainable water use.
Metrics can also be helpfully employed to compare the
performance of individual components and processes
within the data centre which means that it is possible
to get an accurate measure of the solutions offered by
a variety of suppliers.
Rittal has just published a white paper Metrics in IT
and Data Centre Technology which provides a detailed
summary of the most important metrics currently
recommended for the IT infrastructures of data centres.
The White Paper, which provides the necessary formulae
and calculations behind each metric, also makes clear
that individually they would not be sufficient to build up
an accurate picture and that data centre operators need
to define an appropriate set of different parameters that
are tailored for their particular applications. By
continuously recording data, benchmarking performance,
and analysing trends, operators can identify how to ensure
their data centres function efficiently and sustainably.
