In the data center, power and cooling costs more than the IT equipment it supports

In the data center, power and cooling costs more than the IT equipment it supports: "Historically, the cost of energy and the cost of the data center power and cooling infrastructure have not been on the radar for most Chief Financial Officers (CFO) and Chief Information Officers (CIO) and have not been considered in TCO (Total Cost of Ownership) models. As a result, almost all of the focus has been on driving down the cost of IT equipment in the data center. This was a reasonable assumption during the 90’s when server power and energy costs were substantially lower. However, as shown by the ASHRAE power trends curve in Figure 1, power density has been increasing at an alarming rate. During this same period of rapid power growth, server costs have stayed virtually flat and raw performance has increased substantially as shown in Figure 2."
