Measuring the effects of a business sustainability program can
be difficult, but BnY Mellon has managed to put a number on one part of
its efforts to reduce its energy "footprint." savings of $17.8 million (January
2007-august 2013) is solely attributed to the bank's Power usage effectiveness
(Pue) program. Pue is a data center efficiency metric that equals total power
usage of a data center divided by the power used to run the it infrastructure.
efficiency improves as Pue decreases toward one, and the bank brought the
average of its three data centers from 2.9 down to 1.63 in its best month.
under Pue, BnY Mellon's data center managers shared best practices,
spoke with equipment makers, and talked with their it group about planned,
future equipment purchases to come up with energy efficient upgrades. these
varied according to data center, but included installing variable-speed drives on
server fan systems and increasing the supply-air temperature to the servers from
72 to 78 degrees. these improvements are partly the result of an initiative to
generate ideas from the bottom up that enhance sustainability at BnY Mellon's
