IT CAN LEAD YOUR COMPANY’S ENVIRONMENTAL INITIATIVES

“IT will be a significant part of corporations’ efforts to make their internal operations greener, given its disproportionate share of energy consumption relative to headcount or overall operating costs. As a leader of an IT organization, if you haven’t gotten the knock on your door yet from someone asking how and when IT will contribute, you will.”

“Green IT is a sterling opportunity for the IT organization to be a role model for other functional groups in the company. By greening its own operations and serving as an enabler for a broader set of green business opportunities, IT can accelerate its own transformation from a service organization into a full participant in business strategy and contributor to business results.”

"Creating the Green IT Action Plan" (Forrester Research, Inc. October 19, 2007)

IT EXECS ARE PREPARING FOR SIGNIFICANT DATA CENTER CHANGE 52% are willing to pay 5% to 10% more for green

products

51% are willing to trade 5 to 10 percent of server performance for lower carbon emissions

42% say their companies don’t monitor IT-related energy spending

12% say energy efficiency is a critical issue when buying IT equipment following reliability (63%), price (32%) and after-sales support (30%)

FACILITIES GENERALLY OWNS THE ELECTRIC BILL

DELL CONFIDENTIAL 11Source: InformationWeek Research, Green Datacenter Study, September 2007

IT receives incentives from management to

keep electric costs low

IT pays the electric bill: if IT saves on

electricity, the savings can be spent elsewhere

IT sees the bill and is

responsible for minimizing it

IT is aware of the electric bill, but

isn't responsible for managing it

The Facilities team gets the

electric bill and IT never sees it

CONFLICTS BETWEEN IT AND FACILITIES AGENDAS RESULT IN INEFFICIENCIES

IT DEPARTMENTWhat are the upcoming datacenter changes?

Consolidations and expansions New redundancy requirements Incremental power requirements

Does my IT facility (space, power and cooling capacity) fully support initiatives such as Server Consolidation, Virtualization or HPCC initiatives?

Are the existing server room/data center cooling systems adequate to support the new equipment?

Are the existing server room/data center power distribution systems adequate to support the new equipment/future growth?

What would a major business disruption cost my company per hour? What percentage is related to environmental factors?

FACILITIES DEPARTMENTThe utility company won’t let me have

any more power… I have exceeded the capacity of my

rack… I am literally running out of space… I cannot deploy any more servers until

we bring a new DC online…Power is costing more than my

equipment… I am running out of breakers…The only way I can put another server in

is if I take one out…

– A positive change in the energy usage of IT equipment has a direct affect on power and cooling requirements

– A 10% improvement at the server level nets almost 10% at the facility level

– However, efficiency improvements in cooling or power delivery are relatively independent

– 10% betterment in power delivery efficiency manifests itself as a 2.8% improvement at the facility level
