Power Capping. Delivered only with HP ProLiant and HP BladeSystem, Dynamic Power Capping helps customers reclaim trapped power capacity by safely limiting peak power for a 1 megawatt of power and cooling capacity.1 The requirement to provide continuous access to IT services with almost no downtime, - HP ProLiant BL25p | Dynamic Power Capping TCO and Best Practices White Paper (WW - 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 ProLiant BL25p | Dynamic Power Capping TCO and Best Practices White Paper (WW - 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 ProLiant BL25p | Dynamic Power Capping TCO and Best Practices White Paper (WW - Page 6
