and extend the life of existing data center facilities. This paper will focus on an important new component of the Thermal Logic portfolio called Dynamic Power Capping. Delivered only with HP ProLiant and HP BladeSystem, Dynamic Power Capping helps customers reclaim trapped power capacity by safely - HP BL680c | Dynamic Power Capping TCO and Best Practices White Paper (WW edition - Page 3
to deliver IT services. Also, starting in mid-December, 2008, HP will deliver Dynamic Power Capping, a solution that allows systems administrators to reclaim trapped power and cooling capacity by safely limiting the amount of power consumed by one or more ProLiant servers or HP BladeSystem c7000 - HP BL680c | Dynamic Power Capping TCO and Best Practices White Paper (WW edition - Page 4

following a successful implementation of Dynamic Power Capping. The analysis compares the number of servers that can be allocated to a typical 30Amp 3-phase circuit (208V) when budgeting power via three methods: power supply faceplate, HP Power Calculator or HP BladeSystem Sizer, and Dynamic - HP BL680c | Dynamic Power Capping TCO and Best Practices White Paper (WW edition - Page 6
Comparisons were run using the three power budgeting methods for the ProLiant DL 380 G5 server, ProLiant BL460c G1 server, and ProLiant BL460c G5 server. The difference in the number of servers budgeted using faceplate, power calculator, and Dynamic Power Capping represents the capital cost recovery - HP BL680c | Dynamic Power Capping TCO and Best Practices White Paper (WW edition - Page 7
that, for a typical BL460c G1 configuration, users can potentially increase the number of blade servers deployed per circuit from 16 servers using faceplate to 28 servers using Dynamic Power Capping at max power, an increase of nearly 75%. For the ProLiant BL460c G5 server, the results are even - HP BL680c | Dynamic Power Capping TCO and Best Practices White Paper (WW edition - Page 8

For the BL460c G1 configuration used in our TCO benchmarking (see Appendix), the BladeSystem Sizer indicates that 10 BL460 G1 servers will fit in each c7000 enclosure (20 total).
