hp ProLiant DL320 generation 2 server high-density deployment technical white paper 2 abstract This white paper is intended for use as a planning guide to expedite the concentrated deployment of several HP ProLiant DL320 Generation 2 servers. Use this white paper in conjunction with other documents for the ProLiant DL320 Generation 2 server and Compaq branded rack deployment products.
hp ProLiant DL320 generation 2 server high-density deployment technical white paper 3 IMPORTANT: In this document, derating the input power budget means using less than the maximum rated input power values for the power supply. HP strongly recommends using the installation planner to ensure that the derated power budget will satisfy all the installation requirements, including future upgrade plans.

hp ProLiant DL320 generation 2 server high-density deployment technical white paper 6 The easiest way to calculate the thermal dissipation for the entire rack is to add the input power requirements for all the servers and other units populated in a rack, and then multiply the total input power by 3.41. The “measured input power” section explains more on how adding or removing of an optional subsystem component affects the input power and thermal calculations.
