If you plan on using MDT 2010 to deploy Windows Server 2008 onto HP server hardware, you'll need the HP drivers for your server hardware. Here are some tips on how you can do this. Begin by downloading the latest Proliant Support Pack (PSP), then examine the BP.TXT file which has a list of the devices included in the PSP and the corresponding CP.EXE installer file for each device. Then extract the contents of the CP.EXE in order to get the INF, SYS, CAT files for each device and import the drivers into the Deployment Workbench. Usually you will want to import only boot critical network and storage drivers needed by the Windows PE installation phase. Any other HP server drivers can then be installed later using a silent HPSUM.EXE step in your task sequence.
