DELL CONFIDENTIAL 1 GREEN IT SOLUTIONS

GREEN IS EVERYWHERE DELL CONFIDENTIAL 2

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.

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%) DELL CONFIDENTIAL 4 Sources: Rackspace study of 380 customers in 2007, Economist Intelligence Unit

6 POWER & COOLING SOLUTIONS

ENERGY ISSUES INHIBIT BUSINESS INNOVATION AND GROWTH  Power limitations  Cooling capabilities maxing out  Increasingly difficult to manage hot spots  Space at a premium  Power / Cooling costs greater than cost of IT equipment  Unnecessary energy use / expense  Performance demands increasing  Energy costs rising dramatically DELL CONFIDENTIAL 7

GLOBAL ELECTRICITY PRICES HAVE INCREASED 56% SINCE 2002 DELL CONFIDENTIAL 9 Energy Information Administration:

50% OF DATACENTERS WILL LACK SUFFICIENT POWER & COOLING BY 2008 Source: EPA Report to Congress on Server and Data Center Energy Efficiency; August 2, % of projected total U.S. electricity use 1.2% of total U.S. electricity use 0.8% of total U.S. electricity use

CONFLICTS BETWEEN IT AND FACILITIES AGENDAS RESULT IN INEFFICIENCIES IT DEPARTMENT  What 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 DEPARTMENT  The 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…

POWER & COOLING ACCOUNT FOR 59% OF TOTAL ENERGY CONSUMPTION DELL CONFIDENTIAL 14 –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
