Power & Thermal Budgeting - HP ProLiant DL360 Manual

hp ProLiant DL360 generation 3 server high-density deployment technical white paper
IMPORTANT: In this document, derating the input power budget means using less than the
maximum rated input power values for the power supply. Be sure the derated power budget
satisfies all the installation requirements, including future upgrade plans.
Refer to the HP ProLiant DL360 Generation 3 Server QuickSpecs for detailed specifications and
options for the ProLiant DL360 Generation 3 server.
Note: In this document, derating the input power budget means not using the maximum rated
input power values for the power supply. It is strongly recommended that the installation
planner ensures the derated power budget satisfies all the installation requirements,
including future upgrade plans.
power & thermal budgeting
accounting for server input power
All ProLiant DL360 Generation 3 power requirement discussions in this document are based on
the input power of the server, since this number has direct impact in planning for the PDU
selection and the facility power source. Use one of the following methods during the facility
power distribution planning to account for the server input power.
1. Use the maximum rated input power of the power supply: 445 W.
2. Use the Power Calculator Utility (provided in ActiveAnswers) to configure your system as it
will be used; providing all the relevant power and cooling parameters needed to plan an
installation. For more information on the Power Calculator Utility, refer to
activeanswers.compaq.com/aaconfigurator/PowerCalc/DL360Generation 3.xls
3. Use the derated input power, which can be calculated by adding the power budgets of
installed optional components from the rated input power.
4. Use the allocated input power, which can be calculated by dividing the maximum power of a
PDU by the number of servers. This calculated power should be at least 365 W to support all
the optional components initially released with the server.
The power budgets of optional components referred to in the following sections were derived
from the system input power of a set of selectively measured server configurations. The
configurations measured range from a basic low-end configuration to a fully populated high-end
configuration. Since the input power values for a ProLiant DL360 Generation 3 server in an
installation might vary depending on the software applications, the information provided in this
section should be used as a guideline only.
The server power supply is designed to support future upgrades of processors, DIMMs, and hard
disk drives. As such, the power supply output power is rated at 325 W. Considering the power
supply efficiency of 73 percent (including the Power Factor Correction), the power supply input
power is rated at 445 W. This input power value may be used in planning for the power source
implementation and facility cooling requirements. In some cases the input power requirement for
each server might be desired to be lower than 445 W. For example:
•
To minimize the number of PDUs, that is, the number of facility power feed lines, required
for each rack
