       An Intelligent Approach
               to IT Challenges
A Giant Leap for IT and Business Capabilities
                           In many organizations, IT infrastructure has begun to constrain business efficiency
                           and growth. For the past decade, IT has rapidly added low-cost hardware to accom-

                           terms of power, cooling, and floor space, IT infrastructure is actually limiting IT from
                           investing in innovation. IDC estimates that for every dollar IT spends on hardware
                           to support new users and applications, they spend another 50 cents on power
                           and cooling for existing hardware.1
