are the days when the IT staff could assume that they had the power and cooling they required to meet the growing demand for IT services. The Hewlett-Packard Thermal Logic portfolio helps customers reduce data center power consumption, reclaim a large portion of trapped data center power and cooling - Compaq BL10e | Dynamic Power Capping TCO and Best Practices White Paper (EMEA ed - Page 3
being asked to find creative ways to reduce power consumption and better utilize existing facilities while maintaining or improving the quality of IT service delivery.

the number of servers budgeted using faceplate, power calculator, and Dynamic Power Capping represents the capital cost recovery potential of the Dynamic Power Capping solution. The SpecJBB benchmark was used to generate load for the Dynamic Power Capping portion of the TCO analysis.4 Data for the - Compaq BL10e | Dynamic Power Capping TCO and Best Practices White Paper (EMEA ed - Page 7
While customers who use faceplate as their primary means of budgeting server power will see the most dramatic increase in servers per circuit and the most dramatic decrease in power provisioning cost per server, most customers will gain the ability to reclaim trapped power capacity at some level.
