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 Capping and setting server or blade - HP DL360 | Dynamic Power Capping TCO and Best Practices White Paper (EMEA editio - Page 4
over time Time (hrs) At the Rack Level Dynamic Power Capping operates within each HP ProLiant server. In an HP BladeSystem environment, it also functions at the enclosure level. Within individual rack-mount servers, the HP Integrated Lights-Out (iLO 2) management processor works in conjunction with - HP DL360 | Dynamic Power Capping TCO and Best Practices White Paper (EMEA editio - Page 5
power via three methods: power supply faceplate, HP Power Calculator or HP BladeSystem Sizer, and Dynamic Power 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 5 - HP DL360 | Dynamic Power Capping TCO and Best Practices White Paper (EMEA editio - Page 6
. Case 1. HP ProLiant DL380 G5 Server Comparisons of faceplate, power calculator, and SPECjbb benchmark with Dynamic Power Capping for the DL380 G5 are listed below (Table 1). By leveraging Dynamic Power Capping at 100% load, test results showed that, for a typical DL380 G5 configuration, users can - HP DL360 | Dynamic Power Capping TCO and Best Practices White Paper (EMEA editio - Page 7

Power Calculator output becomes the initial Dynamic Power Cap for your ProLiant rack-mount server. Based on the HP Power Calculator output for our ProLiant DL380 G5 configuration, we would set the initial Dynamic Power Cap at 450 Watts. • Using Insight Control Environment, observe peak power usage - HP DL360 | Dynamic Power Capping TCO and Best Practices White Paper (EMEA editio - Page 10
• First, download and apply the following updates to your HP ProLiant server (see Appendix for list of supported servers): Table 6.
