portfolio called Dynamic Power Capping. Delivered only with HP ProLiant and HP BladeSystem, Dynamic Power Capping helps customers reclaim trapped power capacity by safely limiting peak power consumption without impacting system performance. This paper explores how power allocation typically works - Compaq BL10e | Dynamic Power Capping TCO and Best Practices White Paper (WW edit - Page 3
posed by increasing data center power and cooling costs. First, HP energy-efficient servers deliver maximum performance per watt, helping reduce the amount of power required to deliver IT services. Also, starting in mid-December, 2008, HP will deliver Dynamic Power Capping, a solution that allows - Compaq BL10e | Dynamic Power Capping TCO and Best Practices White Paper (WW edit - Page 4

In an HP - Compaq BL10e | Dynamic Power Capping TCO and Best Practices White Paper (WW edit - Page 5
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 - Compaq BL10e | Dynamic Power Capping TCO and Best Practices White Paper (WW edit - Page 6
Capping. 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 - Compaq BL10e | Dynamic Power Capping TCO and Best Practices White Paper (WW edit - 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 more - Compaq BL10e | Dynamic Power Capping TCO and Best Practices White Paper (WW edit - Page 8
mount servers using the ProLiant DL380 G5 server as an example. The second portion of this section described the same process for HP BladeSystem infrastructure using the ProLiant BL 460c G1 and G5 servers and the HP BladeSystem c7000 enclosure as examples. Dynamic Power Capping is part of HP Insight - Compaq BL10e | Dynamic Power Capping TCO and Best Practices White Paper (WW edit - Page 9
When using the HP Power Calculator default settings for our DL380 G5 TCO benchmark configuration (see Appendix), our configuration yields a power estimate of 450 Watts. • The HP Power Calculator output becomes the initial Dynamic Power Cap for your ProLiant rack-mount server. Based on the HP Power - Compaq BL10e | Dynamic Power Capping TCO and Best Practices White Paper (WW edit - Page 10

If the Dynamic Power Cap for the enclosure is invoked too frequently, it may have an adverse impact on server performance. In these situations, you may want to remove - Compaq BL10e | Dynamic Power Capping TCO and Best Practices White Paper (WW edit - Page 12
IT and facilities administrators accurately measure power consumption on one or more ProLiant servers or BladeSystem c7000 enclosures. With the addition of Dynamic Power Capping to Insight Control Environment, it is now possible to limit peak power usage and, using the best practices outlines in - Compaq BL10e | Dynamic Power Capping TCO and Best Practices White Paper (WW edit - Page 13
