Trends & Challenges of Green IT

According to recent reports from Gartner, Forrester,
and McKinsey, the #1 driver for Green IT is to reduce
operating expense.

"Doing the right thing for the environment" is a top
motivator
-

and the escalating cost of energy place
"Green IT" as one of the top agenda items for IT.

Local carbon taxes, regulations, LEEDS compliance and
even federal energy star ratings are emerging too…

Hidden Cost of IT


The “hidden costs” are real and can exceed server acquisition cost


Globally


these costs are often not in the IT budget


Power requirements per $1 thousand in hardware costs 4
-
6x more


Server population doubled between 2000 and 2005


and is on
track to add another 10m servers globally by 2010

Challenge Old Assumptions


Facilities management and IT strategy
are discrete functions


Teaming up results in more energy efficient
solutions


We've always done it this way


Raised floors in DC are artifacts of mainframe days


Cold aisle/hot aisle layout enabled power and
cooling delivery from overhead and is much more
energy efficient


High
-
tech problems require new
technology to solve


Explore low
-
tech options


Consider vinyl curtain for creating physical barrier
between hot and cold aisle; thus saving us more
than $1M KWh/year



Data Centers have to be really cold


Stop overcooling of systems
--

gradually moved up
from 52
ºF


Resulted in less cooling, more hours of free cooling
using outside air


The machines need to be close to
support personnel


Global NOCs work remotely just fine


Remote builds and Administration do too


Each application needs dedicated
serves and storage


Consolidation is easy and transparent


Virtualization is here


work through it and move on


Rack and data center space
management and the application level


Create shared core services


Separate only for compliance or true business
reasons


New technology takes a long time to
have a meaningful impact


High density drives and de
-
duplication have very
fast and significant impacts


NetApp FlexVol and FlexClone can have a
dramatic effect on total storage (power) required to
support complex application development

Maximize FREE cooling.
Eonomizer air handlers with
variable speed fans distribute cool
outside air in the data center and
exhaust the hot air through the
building louvers. In Sunnyvale, we
use outside air for free cooling on
average about 68% of the year.

Connecting Generations: The Sourcebook

by Claire Raines

“Millennials”


Born between 1980 and 2000, they’re a generation nearly as large as the Baby Boom


Charged with potential


Sociable, optimistic, talented, well
-
educated, collaborative, open
-
minded, influential, and
achievement
-
oriented.


Feel sought after, needed, indispensable


Arriving in the workplace with higher expectations than any generation before them


So well connected that, if an employer doesn’t match expectations, they can tell
thousands of their cohorts with one click of the mouse
